Yearly Maintenance
—
Repeat quarterly maintenance and inspection.
—
Check whether connectors are loose or not every year.
—
Make a discharge test to check with exact load every year, discharging 30-40% of rated
capacity.
6.4.
Three-year Maintenance
Make an 80% capacity test every year after three years’ operation.

Operation and Maintenance Precautions
－
Insufficient Charge
If the floating voltage is not set correctly (too low or not amend according to temperature),
the battery system will in an insufficient charge state for a long period of time. When the
electricity is out, the battery may not be able to work because the acid is satirized and the
capacity is decreased.
－
Over Charge
Please do not neglect the performance of rectify to transfer floating charge to equalization
charge. If the rectify cannot transfer charge modes because of its wrong performance or no
adjustment, the battery system is always in an equalization charge state. Thus may cause serious
problems for battery, such as water loss, life decrease, heat out of control, deformation, etc.
－
Too low or too high temperature
We have mentioned that too low temperature will affect the capacity of battery. While too
high temperature will also cause problems, such as water loss, life decrease, heat out of control,
deformation, etc.
－
Too low end voltage
The end voltage is also an important parameter for battery. The battery shall stop
discharge when reach a certain voltage (The normal end voltage is 1.80V/cell per block at 10h
rate). If the end voltage is too low, it will be difficult to recharge the battery and decrease the
charge efficiency, thus reduce the life of battery.
－
Put the battery aside after discharge
