Before battery maintenance, get the tools, such as handles, insulated. Do not place metal
tools on exposed battery terminals.
Never use any organic solvent to clean batteries.
Never try to remove the safety valve or fill anything into batteries.
Never smoke or use fire around batteries.
After battery discharge, charge batteries to ensure a required battery capacity.
Only professionals are allowed to perform maintenance tasks.
If batteries have not been discharged for a long time, discharge and 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 4 hours.
In high-temperature areas, discharge and charge batteries once every two months. Each
charge should last at least 4 hours.
Do not overdischarge batteries. After discharging batteries, fully charge them within 24
hours.
Ensure that the battery discharge duration is 999 minutes at most and 0 minute by default.
If you set the value to 0 minute, the discharge time is not limited.
