Surrette Rolls 6 CS 21P 710Ah 6V Deep Cycle Battery

The Surrette Rolls 6 CS 21P (6 CS 21PS / 6 CS 21P) is a 6 Volt deep cycle battery rated at 916 Ah @ 100 hours rate. Surrette series 5000 batteries feature a reinforced dual case with a small footprint. They come with a 5-year warranty, but with proper care, you can expect a life cycle of 15 -20 years.

Rolls Surrette deep cycle batteries are extensively used in large renewable energy systems. The table below offers the Ampere hour capacity ratings based on the specific gravity of 1.280 at 25°C (77°F). For calculations, reduce capacities 5% for specific gravity of 1.265 and 10% for 1.250.

Surrette Rolls designed the series 5000 batteries for heavy-duty industrial use. They feature a reinforced plate grid, double insulated with a polyethylene and glass mat envelope to protect against positive plate breakdown. The robust construction prevents treeing, cracked or misaligned separators and eliminates shorting at the bottoms or sides of the battery.

The cells are each built into a separate polypropylene container with a thermally bonded cover to prevent acid leakage. The cells are then placed within an outer container of durable polyethylene with a removable lid. The double case construction ensures that the battery is operable and that it won’t spill, even if the outer case is damaged.

The CS and KS series of the Surrette Rolls industrial batteries allow for disassembly, where each cell can be removed independently, making it possible for each cell to be replaced without special tools. Here are some other battery models with similar specifications.
