7.2 Lead-Acid Battery Maintenance
Battery Maintenance Precautions
● Before maintaining batteries, insulate tools such as wrenches. Do not place
any objects on the top of batteries.
● Do not use any organic solvent to clean batteries.
● Do not remove the safety valve or ll anything into batteries.
● Do not smoke or use an open ame around batteries.
● After batteries are discharged, charge them in time to avoid aecting their
lifespan.
● Only professionals are allowed to perform the maintenance tasks.
● If batteries have not been discharged for a long time, charge them in
equalized mode at least once every three months to activate them. Each
charge should last at least 4 hours.
● Normally, discharge and charge batteries once every four to six months. Each
charge should last at least four hours.
● In high-temperature areas, discharge and charge batteries once every two
months. Each charge should last at least four hours.
● Do not overdischarge batteries. After discharging batteries, fully charge them
immediately (or within 24 hours) to avoid aecting the battery capacity.
● The maximum battery discharge duration can be set to 0 hours to 24 hours.
The default value is 16Hour. If you set the value to 0Hour, the discharge time
is not limited.
● The battery module consists of VRLA batteries. The battery service life
depends on the ambient temperature and number of charge and discharge
times. Using batteries in hot environment or deep discharge will shorten the
battery service life.
● The standard operating temperature for batteries is 25°C. Running batteries at
a temperature higher than 25°C will shorten the battery service life; running
batteries at a temperature lower than 25°C will reduce the battery capacity.
● To maintain the battery service life, ensure that the ambient temperature is
between 15°C and 25°C.
● Keep batteries away from heat sources and air vents.
