Rolls Surrette S-550 battery, 6V, capacity 428Ah / 20h, lead-acid

These lead-acid deep cycle batteries feature positive plates with double insulation. The first insulating layer is made of a woven fiberglass cloth; layer which will be finally sealed inside an envelope in microporous polyethylene almost indestructible. This wrap helps prevent separator misalignment, separator cracking, watery tree formation, and bottom and side shorts. It also eliminates the presence of a sediment chamber and therefore leaves more space for the liquid, thus reducing the frequency of refills.
