3 Preparatory operation

DANGER(1) Provide enough insulation between the battery lead

wires and the joint part and the equipment body soas not to cause shorting. Inadequate insulation posesa potential hazard of electric shock to personnel.Oversupply of current due to shorting may result infumes, ignition or fire and could cause burns topersonnel.

CAUTION(1) Do not connect the battery directly to a power outlet

or a cigarette lighter socket of an automobilewithout using a charger. Direct connection to powersources may cause battery leakage, heating orbursting.

(2) Turn off the switch of the circuit when connecting

the battery to a charger or a load.

(3) If newly purchased batteries exhibit any irreg-ularities in initial use, such as rusting, heating orother problems, they should not be used. Continueduse of an irregular battery may lead to leakage, fireor bursting of the battery.

RECOMMENDATION(1) Always charge a newly purchased battery before use

and also charge a battery which has not been in usefor a long period. The battery gradually loses itscapacity due to self discharge during storage. If thebattery is used without being charged, its capacitymay not be fully utilized. Periods over which thebattery can be stored without charging are givenbelow in relation to storage temperatures.below 68F (20C): 9 months68F to 86F (20C to 30C): 6 months86F to 104F (30C to 40C): 3 months

4. Applications other than those specified

1. CAUTION(1) Do not use the battery for applications other than

those specified. Such use may cause battery leakage,fire or bursting.



5. Method of use

DANGER(1) Do not connect the (+) and (-) terminals of the

battery to each other with a metallic material such aswire; do not allow tools such as pipe wrenches andwrenches to touch points of different voltages on thebattery; and do not bring metallic necklaces or hairpins into contact with the battery or store themtogether with the battery. Failure to observe theseprecautions may cause the battery to overheat, emithydrogen gas, leak, ignite, or burst.

WARNING(1) Do not throw the battery in fire nor heat the battery.

The battery may burst or generate a toxic gas ifplaced in contact with fire.

(2) Do not attempt to disassemble, remodel or destroy

the battery, as it may cause battery leakage, fire orbursting, and could also create sulfuric acid spillsfrom the battery resulting in possible burns topersonnel and damage to the immediateenvironment.

CAUTION(1) Check the battery for any sign of irregularities in

appearance. If there is any damage to the batterycase/cover such as cracks, deformation the leakage,replace the battery with a new one. If the batteryappears dirty or dusty, clean it. If a battery ofirregular appearance continues to be used, decreaseof capacity, leakage of electricity, fumes, ignition orother problems may result.

(2) If any irregularity is found in areas such as the

charge voltage and discharge characteristics of thebattery, replace it.

(3) For safety, make sure to observe the following:Otherwise, leakage, fire or bursting of the batterymay occur.1) Do not charge the battery with its (+) and (-)

terminals and the (+) and (-) terminals of thecharger connected in reverse.

2) Do not apply a solder directly to the battery. Ifdirect soldering is unavoidable, please contactPanasonic in advance.

3) Avoid mixed usage of batteries differing in type,manufacturer or history of use.

4) Do not remove or damage the outer case of thebattery.

5) Do not apply a strong shock to the battery orthrow it.

(4) Do not continue to charge the battery beyond thetime specified in the instructions of use of thecharger. If the battery is not fully charged even afterbeing charged for a longer time than specified,discontinue charging and remove the battery fromthe charger. Charging for a longer time thanspecified may cause battery leakage, fire or bursting.

(5) Children should only use the battery under the

guidance of an adult who should thoroughly instructthe child on its use. During use the adult shouldcheck that the battery is used exactly as instructed.

Keep the battery beyond the reach of small children.During charging or actual use of the battery, takecaution not to allow small children to remove the batteryfrom equipment.



RECOMMENDATION(1) The recommended discharge stop voltage depends

on the size of the discharge current. The relationshipbetween the storage battery discharge current andthe ideal discharge stop voltage is described in thespecifications and catalogs.Do not continue discharging to the point where thevoltage drops below the recommended dischargestop voltage.If a storage battery that was discharged below therecommended discharge stop voltage is recharged,the storage battery will generate heat which coulddeform it or cause water droplets to form on thebattery casing due to the evaporation of moisturefrom inside the battery. Discharging below therecommended discharge stop voltage may alsoaccelerate the deterioration of the battery'sperformance characteristics.

(2) Avoid overdischarge, and charge the batteryimmediately after discharge. The instruction manualof the equipment should contain information tellingthe user not to overdischarge the battery and tocharge the battery immediately after the use of theequipment (discharge). Even if discharge of thebattery is stopped before voltage decreases to such alevel that the battery- driven equipment stops beingoperational, deterioration of the battery may beaccelerated by the so-called sulphation phenomenonif it is not recharged after use. The low voltage cut-off circuit should be designed so that it cancompletely cut off the discharge current including aweak current.

(3) If a charge method and a charge condition other thanthat described in the specification and the technicalbrochures is to be adopted, charge/dischargecharacteristics and life characteristics of the batteryshould be thoroughly checked in advance. Theadoption of adequate charge methods and adequatecharge conditions are crucial to ensure safe use ofthe battery and for fully utilizing the batterycapacity.

(4) For the cycle operation of the battery (application ofthe battery as the main source of power by repeatingcharge and discharge), adopt a charger whichoperates by controlling either the charge period orcharge quantity. Continue charging the battery forthe time specified or until the charge completionlamp, if provided, indicates completion of charge. Ifcharging is suspended before completion, theservice life of the battery may be shortened.

(5) Avoid parallel charge of batteries in cycle operation,

as this may shorten the service life of the batteriesby causing an imbalance in charge/discharge stateamong the batteries connected in parallel.

(6) During trickle or float charge of the battery, measure

the total voltage with a high-accuracy voltmeter ofClass 0.5 or so. If the voltage readout does not meetthe specified value, investigate the reason and takeproper measures. A total voltage that is lower thanthe specified value indicates insufficient chargewhich may reduce the battery capacity; a voltagehigher than specified indicates an overcharge whichmay shorten service life of the battery or causeproblems such as thermal runaway in some cases.

(7) Make sure to turn off the switch of the battery

equipment after use, otherwise excessive dischargemay cause deterioration in battery performance andshorten service life.

(8) When equipment is not used for a long period,

remove the battery from the equipment, charge itfully, and store it in a place where humidity is low.Unsatisfactory storage conditions may causedeterioration in battery performance, shorten servicelife and could cause rusting.



Maintenance and checking

1. WARNING(1) Clean the battery with a slightly damp cloth, ensure

there is no excess water on the cloth by squeezing itwell. Do not use a dry cloth or a duster, as it maycause the battery to generate static electricity,leading to possible ignition and bursting of thebattery.

(2) Replace the battery with a new one within the time

period specified in the instruction manual orequipment.

Follow the guideline which states the battery shouldbe replaced when its capacity has decreased to 50%of the initial capacity (at an ambient temperature of77F (25C) or below). In the trickle or floatapplication of the battery (application as stand-bypower) at an ambient temperature higher than 77F(25C), the period for which the battery can be usedbefore replacement is shortened by a half for every50F (10C) rise of temperature. When dischargecurrent becomes higher than 0.25 CA, the use periodbefore replacement is also shortened.

The usable period for the battery is markedlyshortened near the end of its service life (whendischarge time has decreased to 50% of the initial).This is also the period when battery problems suchas internal short, dry-up of electrolyte (increase ininternal resistance) and corrosion of the cathodegrids will occur. Replace the battery before theseconditions are reached: if the battery continues to beused under these conditions, maximum dischargecurrent will continue flowing, which may lead tothermal runaway or leakage.

CAUTION(1) Do not apply organic solvents such as paint thinner,

gasoline, kerosene and benzene or liquid detergentsto the battery. If these are brought into contact withthe battery case, it may crack, causing leakage.

RECOMMENDATION(1) Keep the terminals of the battery clean. Dirty

terminals may cause inadequate contact of thebattery to the equipment body, leading to powerfailure or charge failure.

7. Emergency measures

1. WARNING(1) The battery contains diluted sulfuric acid, a very

toxic substance. If the battery leaks and the liquidinside spills on the skin or clothing, immediatelywash it off with plenty of clean water. If the liquidsplashes into eyes, immediately flush the eyes withplenty of clean water and consult a doctor. Sulfuricacid in the eyes may cause loss of eyesight and acidon the skin will cause burns.

CAUTION(1) If any corrosion of the terminals, leakage or

deformation of the case of the battery is found, donot use the battery. If a battery which is irregular orsubstandard in any way continues to be used,leakage, fire or bursting of the battery may occur.


PRECAUTIONS ON HANDLING SEALED LEAD-ACID BATTERIES - CONTINUED

8. Storage of batteries

CAUTION(1) Store the battery in a stable position so as to keep

the terminals of the battery away from any metallicor other conductive material (including items thatmay fall or drop onto the battery).

(2) Protect the battery from rain. If the terminals of the

battery come into contact with water, they may becorroded.

(3) Keep the battery in the upright position as a general

rule, and do not apply abnormally strong vibrationsor shocks to the battery. Transportation of thebattery in an abnormal position or the application ofabnormally strong vibrations or shocks to the batterymay cause damage to the battery and the deterio-ration of characteristics.

(4) When storing the battery, remove it from the

equipment or disconnect it from the charger or theload and keep it in a place where temperature is low.Do not store the battery under direct sunlight or inhigh temperatures (140F (60C) or higher) or in ahighly humid atmosphere, because rusting,deterioration of performance and life of the batterymay occur.

RECOMMENDATION(1) During storage of the battery, charge it at least once

every six months (when ambient temperature is 77F(25C) or below). Shorten the interval of charging toa half by every 50F (10C) rise of ambienttemperature. Rate of self discharge of the batterydoubles by every 5F (10C) rise of ambienttemperature. If the battery has been stored for a longperiod in a discharged state, it may not be able toregain it's capacity even if it is recharged.

(2) If the battery is stored for a year or longer without

being charged, its service life may be shortened. (3) Store the battery after fully charging it, otherwise its

service life may be shortened. (4) Use the battery as soon as possible. The battery

gradually deteriorates during storage and thus itsdecreased capacity may be irreversible evenallowing for recharging.

9.Disposal of batteries

CAUTION(1) In countries where there are legal or voluntary

regulations on the recycling of rechargeablebatteries, please provide written information onrecycling of rechargeable batteries which is includedin equipment, packaging, instruction manuals, etc.

(2) Adopt methods and measures for equipment design

and battery mounting that will allow for easyremoval of batteries for replacement and disposal.

(3) Used batteries are recyclable. When returning usedbatteries, insulate their terminals with adhesivetapes, etc., otherwise the residual electricity in usedbatteries may cause a fire or explosion.

(4) This battery is fully recyclable and should beaccepted at any location that accepts commonautomotive starter batteries. Examples of placesthat accept these batteries are: County or municipalrecycling drop-off centers, scrap metal dealers, andretailers who sell automotive replacement lead acidstarter batteries. In North America, non-consumerscan call 1-800-SAV-LEAD for assistance inrecycling.


SEALED LEAD-ACID BATTERIES

Overview

Our sealed lead-acid battery (SLA battery) has been onthe market for more than 25 years. The SLA battery is arechargeable battery which requires no watering.Adopting lead-tin- calcium alloy as the grid alloy, it hasoutstanding characteristics against severe use conditionssuch as overcharge, overdischarge, vibration, shock andalso for various storage conditions. Our accumulation oftechnologies has enabled us to respond to marketrequirements promptly by developing compact, lightweight products and improving charging capabilities toallow for quick charging in 1 to 3 hours.

The SLA battery covers a broad range of applicationsincluding advanced equipment such as VTRs and

computers, electric tools, engine starters, UPS, and otherback-up power applications. In addition to the LC-Vseries, which provides an option for meeting the needfor a resin battery case that is flame-retardant, we havealso met the needs of the market with the Trickle LongLife Series, which has an expected trickle life of 6 yearsat 77F (25C). 1 Temperature 77F (25C), discharge rate 0.25 CA/1.75V/cell, discharge frequency every 6 months,2.275V/cell charge 2 Temperature 77F (25C), discharge rate 0.25 CA/1.75V/cell, discharge frequency every 6 months.

GENERAL INFORMATION ON SEALED LEAD-ACID BATTERIES

Construction and electrolyte

Positive plates Positive plates are plate electrodes of which a grid frameof lead-tin-calcium alloy holds porous lead dioxide asthe active material. Negative plates Negative plates are plate electrodes of which a gridframe of lead-tin-calcium alloy holds spongy lead as theactive material. Electrolyte Diluted sulfuric acid is used as the medium forconducting ions in the electrochemical reaction in thebattery. SeparatorsSeparators, which retain electrolyte and prevent shortingbetween positive and negative plates, adopt a non-wovenfabric of fine glass fibers which is chemically stable inthe diluted sulfuric acid electrolyte. Being highlyporous, separators retain electrolyte for the reaction ofactive materials in the plates.

Valve (One way valve) The valve is comprised of a one-way valve made ofmaterial such as neoprene. When gas is generated in thebattery under extreme overcharge condition due toerroneous charging, charger malfunctions or otherabnormalities, the vent valve opens to release excessivepressure in the battery and maintain the gas pressurewithin specific range (0.07 to 0.43 kPa, or 1 to 6 psi).

During ordinary use of the battery, the vent valve isclosed to shut out outside air and prevent oxygen in theair from reacting with the active material in the negativeelectrodes. Positive and negative electrode terminals Positive and negative electrode terminals may be Fastontab type, bolt fastening type, lead wire type or lead strip type, depending on the type of the battery.Sealing of the terminal is achieved by a structure whichsecures long adhesive-embedded paths and by theadoption of strong epoxy adhesives. For specificdimensions and shapes of terminals, see page 61. Battery case materials Materials of the body and cover of the battery case areABS resins, unless otherwise specified.

Electrochemical reactions on electrodes

The electrochemical reaction processes of the sealedlead-acid battery (negative electrode recombinationtype) are described below. Where "charge" is the operation of supplying therechargeable battery with direct current from an external

power source to change the active material in thenegative plates chemically, and hence to store in thebattery electric energy in the form of chemical energy."Discharge" is the operation of drawing out electricenergy from the battery to operate external equipment.

Miscellaneous uses: Integrated VTR/VCR,Tape recorders, Handy cleaners, Other portableequipment, etc.

*(Note) When any medical equipment incorporating a Panasonic SLA batteryis planned, please contact Panasonic.

Features

Leak-resistant structure A required-minimum quantity of electrolyte isimpregnated into, and retained by, the positive andnegative plates and the separators; therefore electrolytedoes not flow freely. Also, the terminal has a sealedstructure secured by long adhesive-embedded paths andby the adoption of strong epoxy adhesives which makesthe battery leak-resistant. (Note) In stand-by/back-upuses, if the battery continues to be used beyond the pointwhere discharge duration has decreased to 50% of the initial (i.e. life judgment criteria), cracking of the batterycase may occur, resulting in leakage of the electrolyte. Long service life Service life of our long-life series (LC-P, LC-X seriesand LC-TA122P(a), LC-T122P(a)) batteries isapproximately double that of the conventional (LC-T,LC-R and LC-L series) batteries (Temperature 77F(25C), discharge rate 0.25 CA/ 1.75V/cell, dischargefrequency every 6 months, 2.30V/cell charge).

Easy maintenance Unlike the conventional batteries in which electrolytecan flow freely, SLA batteries do not need the specific-gravity check of the electrolyte nor the wateringstructurally; this makes the battery function fully andmakes maintenance easy. No sulfuric acid mist or gases Unlike the conventional batteries in which electrolytecan flow freely, SLA batteries generate no sulfuric acidmist or gases under the use condition we recommend. Inuses under conditions other than recommended,however, gas generation may occur, therefore do notdesign the battery housing with a closed structure. Exceptional deep discharge recovery As seen in the figure on the next page, our SLA batteryshows exceptional rechargeablity even after deepdischarge, which is often caused by failure to turn offthe equipment switch, followed by standing (approx. 1month at room temperature is assumed).

CHARACTERISTICS

Charging Charge characteristics (constant voltage-constant currentcharging) of SLA batteries are exemplified below. Example of constant-voltage charge characteristicsby current In order to fully utilize the characteristics of SLAbatteries, constant-voltage charging is recommended.For details of charging see page 63. Discharginga) Discharge current and discharge cut-off voltageRecommended cut-off voltages for 6V and 12V batteriesconsistent with discharge rates are given in the figurebelow. With smaller discharge currents, the activematerials in the battery work effectively, thereforedischarge cut-off voltages are set to the higher side forcontrolling overdischarge. For larger discharge currents,on the contrary, cut-off voltages are set to the lowerside.(Note) Discharge cut-off voltages given arerecommended values.

Discharge current vs. Cut-off voltage

b) Discharge temperature(1) Control the ambient temperature during discharge

within the range from 5F to 122F (-15C to 50C)for the reason described below.

(2) Batteries operate on electrochemical reaction which

converts chemical energy to electric energy. Theelectrochemical reaction is reduced as thetemperature lowers, thus, available dischargecapacity is greatly reduced at temperatures as low as5F (-15C). For the high temperature side, on theother hand, the discharge temperature should notexceed 122F (50C) in order to preventdeformation of resin materials which house thebattery or deterioration of service life.

c) Effect of temperature on dischargecharacteristicsAvailable discharge capacity of the battery varieswith ambient temperature and discharge current asshown in the figure below.

CHARACTERISTICS - CONTINUED

d) Discharge currentDischarge capability of batteries is expressed by the20 hour rate (rated capacity). Select the battery forspecific equipment so that the discharge currentduring use of the equipment falls within the rangebetween 1/20 of the 20 hour rate value and 3 timesthat (1/20 CA to 3 CA): discharging beyond thisrange may result in a marked decrease of dischargecapacity or reduction in the number of times ofrepeatable discharge. When discharging the batterybeyond said range, please Panasonic in advance.(Note) With some types of SLA batteries whichhave a built-in thermostat, the thermostat may auto-matically cut off the circuit when discharge currentexceeds 4 A at the ambient temperature of 104F(40C); therefore, the maximum discharge currentvalue should be the smaller one of either 4 A or 2CA.

e) Depth of dischargeDepth of discharge is the state of discharge ofbatteries expressed by the ratio of amount ofcapacity discharged to the rated capacity.

Storagea) Storage condition

Observe the following condition when the batteryneeds to be stored.(1) Ambient temperature: 5F to 104F (-15C to

40C) (preferably below 86F (30C))(2) Relative humidity: 25 to 85%(3) Storage place free from vibration, dust, direct

sunlight, and moisture.

b) Self discharge and refresh charge During storage, batteries gradually lose theircapacity due to self discharge, therefore the capacityafter storage is lower than the initial capacity. Forthe recovery of capacity, repeat charge/dischargeseveral times for the battery in cycle use; for thebattery in trickle use, continue charging the batteryas loaded in the equipment for 48 to 72 hours.

c) Refresh charge (Auxiliary charge)

When it is unavoidable to store the battery for 3months or longer, periodically recharge the batteryat the intervals recommended in the table belowdepending on ambient temperature. Avoid storingthe battery for more than 12 months.

Below 68F (20C) 9 months

68F (20C) to 86F (30C) 6 months

d) Residual capacity after storage

The result of testing the residual capacity of thebattery which, after fully charged, has been leftstanding in the open- circuit state for a specificperiod at a specific ambient temperature is shown inthe figure below. The self discharge rate is verymuch dependent on the ambient temperature ofstorage. The higher the ambient temperature, theless the residual capacity after storage for a specificperiod. Self discharge rate almost doubles by each50F (10C) rise of storage temperature.

e) Open circuit voltage vs. residual capacityResidual capacity of the battery can be roughlyestimated by measuring the open circuit voltage asshown in the Figure.

Open circuit voltage vs. Residual capacity (77F(25C))

Temperature conditions Recommended temperature ranges for charging,discharging and storing the battery are tabulatedbelow.

Charge 32F ( 0C) ~ 104F (40C)

Discharge 5F (-15 C) ~ 122F (50C) Storage 5F (-15 C) ~ 104F (40C)

Battery lifea) Cycle life

Cycle life (number of cycles) of the battery isdependent on the depth of discharge in each cycle.The deeper the discharge is, the shorter the cycle life(smaller number of cycles), providing the samedischarge current. The cycle life (number of cycles)of the battery is also related to such factors as thetype of the battery, charge method, ambienttemperature, and rest period between charge anddischarge. Typical cycle-life characteristics of thebattery by different charge/discharge conditions areshown by the Figures.This data is typical and tested at a well-equippedlaboratory.Cycle times are different for each battery model.Cycle times are also different from this data whenusing batteries under real conditions.

BATTERY SELECTION GUIDE

Steps for selecting batteries are described below. Study of required specifications (draft)

Study the required specifications (draft) by

checking the requirements for the battery with thebattery selection criteria. Technical requirements forselecting the battery are presented below.

Technical requirements for battery selection Battery selection First, select several candidate batteries by referring tothe technical brochures and data sheets of the batteriespresently available. Then from the candidates select abattery which can meet as many of the idealrequirements as possible. In fact, however, batteryselection can be seldom made so smoothly. Practically,possible removal or easing of the requirements shouldbe considered first; then depending on the result, aproper battery should be selected from those presentlyavailable. This way of proceeding enables economicselection of the battery. Any questions at this stageshould be asked to battery engineers in depth.Sometimes, new or improved batteries which are notcarried in the brochures have become available, and anappropriate battery may be found among them. Usually,required specifications are finalized at this stage.

Request for improving or developing batteriesIf no battery which will satisfy special requirements canbe found by the above-described approach, requests forimproving or developing new batteries should be madeto our technical department, and these requests shouldbe coordinated as quickly as possible to allow enoughtime for studying: the study takes usually 6 to 12 monthsor even longer depending on the request.In this section, guidelines for selecting appropriatebatteries for specific equipment were mentioned. Iffurther information regarding the battery selection isrequired, please contact us.
