● In order to assure service life, the batteries should be correctly inspected and
maintained. The maintenance methods of GEL batteries are recommended as follows:
● Monthly Maintenance
Implement the under-mentioned inspection every month:
Keep the battery-room clean.
Measure and record the ambient temperature of the battery-room.
Check each battery’s cleanness; check damage and overheating trace of the
terminal, container and lid.
Measure and record the total voltage and floating current of the battery
● Quarterly Maintenance
Repeat monthly inspection.
Measure and record floating voltage of every on-line battery. If more than two
cells’ voltage is less than 2.18V after temperature adjustment, the batteries
need to be equalization charged. If the problem is still existing after adopting
above-mentioned measures, the batteries need yearly maintenance or even
three years’ maintenance. If all methods are ineffective, please contact us.
● 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.
● Three-year Maintenance
Operation manual for OPzV series
Make a capacity test every year after three years’ operation. If the capacity of
the battery decreases to lower than 80% of rated capacity, the battery should
Operation and Maintenance
● 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 discharging when reach a certain voltage (The normal end voltage is
1.8Vwith 10-hour 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 operation and maintenance must co mply with the manual. Please set up
the parameter according to the manual when charging.
●Do not drop any personal watch, jewelry or any other metallic objects when
servicing the batteries. Always wear in sulated gloves during any battery servicing
●Please terminate all switches between the battery, load or charger before making
