The Rolls Surrette 4-CS-17PS is a 4 volt deep cycle battery rated at 770 Ah @ 100 hours rate. This battery is a very high capacity battery with new generation series 5000 advantages and features like: dual case, replaceable cells, small foot print and an expected life of 10 years.
The high capacity, deep cycle Industrial Flooded batteries from Rolls Surrette feature a heavy duty plate grid, double insulated with a polyethylene envelope and a glass mat to protect against positive plate breakdown, as well as prevent treeing, cracked or misaligned separators, or shorting at the bottoms or sides of the battery.
The 2VDC cells are each built into their own lightweight, polypropylene container with a thermally bonded cover to prevent acid leakage, then placed within an outer container of durable polyethylene with a removable lid, ensuring that the battery is operable and unspilled, even if the outer case is damaged.
Both the CS and KS series of the Surrette Rolls batteries allow for disassembly, where each cell can be removed independently. This makes it possible for each cell to be replaced without special tools, and creates ease for on site installation.
