Before battery maintenance, 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 fill anything into a battery.
Do not smoke or use an open flame around batteries.
After battery discharge, charge the battery in time to maintain a good service
life.
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 (within 24 hours) to avoid affecting 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
