Maintenance

● 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

system.


● 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

be replaced.


Operation and Maintenance

● 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 saltilized 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 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.


● Do charge the battery immediately after discharge.

If the battery is put aside without char ge for a long time after discharge, it will

affect the capacity and life of the battery. Because some large size PbSO4 will

create in the negative which are difficult to transfer to active Pb.


Precautions

●Do not drop any personal watch, jewelry or any other metallic objects when

servicing the batteries. Always wear insulated gloves during any battery servicing

activities.


●Do not leave any metallic tools or connectors on the top of the battery.


●Do not use any type of organic solvent to clean the battery.


Applications:

● Telecommunications

● Cable Television

● Electric Utility

● Alarm & Security system

● UPS

● Control Equipment

● Medical Equipment

● Railroad Utility

● Photovoltaic System

● Alternative Energy System

● High Power Backup Supply
