● 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
terminal, container and lid.
Measure and record the total voltage and floating current of the
● 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
need to be equalization charged. If the problem is still existing
above-mentioned measures, the batteries need yearly maintenance or
three years’ maintenance. If all methods are ineffective, please
● 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,
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
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
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
While too high temperature will also cause problems, such as water
decrease, heat out of control, deformation, etc.
● Too low end voltage
The end voltage is also an important parameter for battery. The
stop discharging when reach a certain voltage (The normal end
1.8Vwith 10-hour rate). If the end voltage is too low, it will be
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
servicing the batteries. Always wear in sulated gloves during any
●Please terminate all switches between the battery, load or charger
