Rolls Surrette S-550 battery, 6V, 428Ah/20h capacity, lead acid
These flooded deep cycle batteries feature double insulated positive plates. The first layer utilizes a thick woven glass mat, which then is sealed in a non-destructible micro porous polyethylene envelope. The protective envelope reduces the possibility of separator misalignment, cracked separators, or shorting at the bottom or sides. This also allows the sediment chamber to be eliminated, creating more space for liquid at the top of the battery, thus lengthening periods between watering.
Series 4000 batteries carry a 24 month free replacement warranty and include an 84 month adjustment period from date of installation.
