charging current.
3. Battery cleaning
Use cloth soaked in water or carbonic acid water to clear battery and cover.
4. Capacity test
If batteries work properly, no need to check capacity. Check capacity only when battery capacity is in doubt.
When battery is in discharge, the cut-off voltage should not be lower than the requirement in the technical
manual.
Before capacity testing, make sure battery get fully charged for more than 48 hours under float charge, if not,
make a equalization charge for 24 hours. Let batteries rest and cool down for 8-24 hours and then conduct
capacity test.
