BAE batteries are a quality valve regulated lead acid (VRLA) batteries - perfect for solar power systems. Made by BAE Batterien GmbH in Germany, and available in 686 to 4710 Amp Hour capacity.

BAE Solar batteries are rated 8000 cycles @ 20% Depth of Discharge (meaning your battery remains 80% full). Due to the high cycle life requirements tubular plates are used. They are made for indoor use.
