Always dispose of a replaced battery in an ecologically 
responsible manner. Dispose of used BBUs at authorized 
battery disposal sites only. 

 

Do not use nor leave the BBU near a heat source. Heat can melt 
the insulation and damage other safety features of battery cells, 
possibly will cause acid leak and result in flames or explosion. 

 

Do not immerse the BBU in water nor allow it to get wet. Its 
protective features can be damaged. Abnormal chemical 
reactions may occur, possibly cause functional defects, acid 
leak, and other hazardous results. 

 

Do not disassemble or modify the BBU. If disassembled, the 
BBU could leak acid, overheat, emit smoke, burst and/or ignite. 

 

Do not pierce the BBU with a sharp object, strike it with a 
hammer, step on it, or throw it. These actions could damage or 
deform it and internal short-circuiting can occur, possibly cause 
functional defects, acid leak, and other hazardous results. 

 

If a BBU leaks, gives off a bad odor, generates heat, becomes 
discolored or deformed, or in any way appears abnormal during 
use, recharging or storage, immediately remove it from the 
subsystem and stop using it. If this is discovered when you first 
use the BBU, return it to your subsystem vendor. 

 

 

Replacing a Faulty BBU 

 

*Single controller models, must power down the system if BBU was 
purchased as an option accessory.. 

To replace the BBU, please follow these steps: 

Step 1.

 

Remove the faulty BBU from the chassis

. The BBU module is 

located within the controller canister. Loosen the retention screws 
underneath the levers and pull out the controller. Loosen the captive 
screw at the end of BBU to remove the faulty. 

 

Remove the screws from the controller faceplate and push down on the 
levers
