self-discharge, the batteries should be supplemental charged as storage period shown 
in following table. The equalization charge method should be adopted. 

Storage temperature

months 

 

During storage, if the open circuit voltage is lower than 2.10V/Cell, the batteries 
should be supplementary charged before use. The equalization charge method should 
be adopted. 

 

All batteries, which are ready to store, should be fully charged before storage. It’s 
suggested record the storage time in the periodic maintenance record and record the 
time when another necessary supplementary charge should be made.   

The quality certificates of EosG batteries record the latest charge time of the batteries, 

next charge time can be calculated according to this charge time.

 

 

6. Maintenance     

In order to assure service life, the batteries should be correctly inspected and maintained. 

The maintenance methods of EosG batteries are recommended as follows:

 

z

 

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. 

 

z

 

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 still exists after adopting above-mentioned measures, the batteries 
need yearly maintenance or even three years’ maintenance. If all methods are ineffective, 
please contact us

 

z

 

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.

 

Make a capacity test every three years and every year after six years’ operation. If the 

capacity of the battery decreases to lower than 80% of rated capacity, the battery should be
