Notes for Battery Disposal and Battery Replacement 

1)  Before disposing of batteries, remove conductive jewelry such as necklace, wrist watches and 

rings. 

2)  If it is necessary to replace any connection cables, please purchase the original materials from 

the authorized distributors or service centers, so as to avoid overheat or spark resulting in fire 
due to insufficient capacity. 

3)  Do not dispose of batteries or battery packs in a fire, they may explode. 

4)  Do not open or mutilate batteries, released electrolyte is highly poisonous and harmful to the 

skin and eyes. 

5)  Do not short the positive and negative of the battery electrode, otherwise, it may result in 

electric shock or fire. 

6)  Make sure that there is no voltage before touching the batteries. The battery circuit is not 

isolated from the input potential circuit. There may be hazardous voltage between the battery 
terminals and the ground. 

7)  Even though the input breaker is disconnected, the components inside the UPS are still 

connected with the batteries, and there are potential hazardous voltages. Therefore, before any 
maintenance and repairs work is carried out, switch off the breaker of the battery pack or 
disconnect the jumper wire of connecting between the batteries. 

8)  Batteries contain hazardous voltage and current. Battery maintenance such as the battery 

replacement must be carried out by qualified personnel who are knowledgeable about batteries. 
No other persons should handle the batteries.
