Maintenance

To ensure the performance of battery, the battery should be correctly inspected and maintained. The maintenance methods are recommended as follows.

Monthly Maintenance

■ Keep the battery space clean.

■ Measure and record the ambient temperature of the battery-room and battery container

temperature.

■ Check battery cleanliness, terminal damage and heating track, container and lid damage

and over heating track.

■ Check battery and battery rack connection, spring mat and bolts connected tight or not,

input terminal heating or not, connected terminal between layer heating or not.

■ Check the container sealing, leakage/potential leakage or not in terminal, valve and

container position.

■ Check charge temperature compensation function in normal or not, parameters setting

correct or not, equalizing charge voltage, floating charge voltage period and other parameters reasonable setting or not.

■ Measure and record the total voltage and floating current of the battery system.

Quarterly Maintenance

■ Repeat every item of monthly inspection.

■Measure and record the floating voltage of each on-line battery. After temperature

emendation, if more two batteries with a voltage of lower than 2.18V, the battery system needs equalizing charge. If the problem is not solved, go on annually maintenance even three yearly maintenance items. All the above methods fail, please contact our after-sale service center.

Annually Maintenance

■ Repeat every item of quarterly maintenance and inspection.

■ Check whether the battery beyond service expiry or not.

■ Perform a discharge test to check the exact load every year, discharge 30%-40% of the

rated capacity.

Maintenance notes

■ Please use insulated tools when operation and maintenance, any metal objects to be put on top of the battery shall be strictly prohibited;

■ Please do not use any organic solvent to clean batteries;

■ Please do not take down safety valve or add any substance into battery;

■ Please do not smoke or set out fire near batteries;

■ Please keep battery fully charged within 24 hours after discharge, avoid capacity affected;  Check whether safety valve twisted tightly or not, but please do not take down it;

■ Stored battery performance could be in degeneration, please put the battery in operation

early;

■ Only professionals shall be allowed to maintain the battery.
