Berkey Battery Adapter Case

The Berkey Battery Adapter case is the power source for Berkey Light LED systems or for stainless steel systems that have a Berkey LED base.

The adapter case comes complete with on-off switch for backup power for your Berkey LED system. Using the Berkey Battery Adapter case, the low energy LED's can operate for 8 hours per night or approximately two weeks on a single set of four AA alkaline batteries. Amazing,  two weeks worth of emergency light for the price of one set of small AA batteries.
