The use and maintenance of the Maintenance Free Battery
storage battery pack is constituted by many single battery in series, which provide power for the vehicle. The right use of
the battery will expand its service and driving mileage of the vehicle.
Discharging for the battery:
A. Avoid discharging more than 80% of the rated capacity to expand the service and the discharging should be stopped
when the last light in the indicator gauge blinks. The single batterys voltage should be 12V and the voltage of thebatteries ending should be no less than 10V after the discharging finished, and then the battery should be charged
immediately.
B. If the accumulator discharges too much, then it will need more time to recharge. And the battery will discharge in a low
voltage in the next discharge process. If the circulation continues, the battery will get invalid.
C. After a deep discharging, the battery should get charged as soon as possible and should not be leaved uncharged mor
than one day. In addition, an discharging which is more than 80% of the rated capacity will shorten the service.
Charging for the battery:
A. The battery should not be in a working condition and should get cool down before charging.
B. Only the matching charger is available. Also, the charger and the battery pack should be in the same type.
C. The parking braking should be pulled up and the direction switch should be in the neutral position before and during the
charging, switch it off and pull out the key.
D. Connect the output plug and the charging jack first, then connect an A.C. power
E. When the charging indicator off, the battery gets fully charged.
F. Pull out the Charger plug, then pull out the battery connector when the charging finished.
Charging for the batteries long-stalled and occasionally used: A. A self discharge happens when the battery is not in use and which will lower the charging capacity, cause the
vulcanization and reduce the service of a battery as time goes by.
B. Get the battery fully charged per month and put it in a dry and cool place if the battery is not used frequently.
C. A long-stalled battery should be recharged, the density and the level of the bath solution should be checked when its
get in use again.
