LAB Battery Pack ACG18BP

Lead-Acid Extended 2U Battery Packs 

With these Acumentrics lead-acid battery modules, there is never any need to check specific gravity or replace or top off water. All that is needed is a charge every six months to preserve battery life. 

Non-Spillable Battery 
The lead-acid battery module’s sealed construction eliminates electrolyte leakage from the terminals or case, ensuring safe, efficient operation in any orientation. 

Low Self-Discharge For Longer Life 
At ambient temperatures between 20°C and 25°C, the self-discharge rate of the Acumentrics lead-acid battery module is less than 3% per month. This allows storage for up to six months without significant state-of-charge loss. 

Operate in Any Orientation 
With their sealed construction and electrolyte suspension, Acumentrics’ lead-acid battery modules can be mounted in any orientation, vertically or horizontally. (However, inversion should be avoided.) 

Efficient Gas Recombination 
These battery modules incorporate a unique Absorbent Glass Mat technology that effectively recombines over 99% of the gas generated during normal usage. 

Hot and Cold Weather Operation 
Lead-acid battery modules can be used over a broad range of ambient temperatures, allowing considerable flexibility in system design and location. 

High Recovery Capability 
The Acumentrics lead-acid battery modules have excellent charge acceptance and recovery capability, even after very deep discharge.
