Rolls Battery Engineering and Surrette Battery Company is one of North America's leading lead-acid battery manufacturers. Established in 1935, with a production facility in Salem, Massachusetts, the nation’s only remaining independent battery manufacturer.
Rolls flooded, deep-cycle batteries feature extended standard warranties and double insulated-enveloped positive plates that eliminate the possibility of separator misalignment, cracked separators, treeing, or shorting at the bottom or sides. Each battery cell has increased liquid reserve levels resulting in fewer watering intervals. The 4000 Series is rated for a 10-year average life in cyclic applications and the 5000 Series is rated for up to 15 years. The 4000 series have rope handles, handles on 5000 series are molded into the outer case. The 5000 series are constructed in a non-breakable modular dual container. Each 2-volt cell is assembled in its own inner polypropylene container within a moisture tight, heavy-duty protective outer container eliminating damage during handling or possibility of short circuits due to water or falling metal objects. Series 4000 batteries carry a 24-month free replacement warranty (FOB factory) and include an 84-month adjustment period from date of installation. Series 5000 batteries carry a 36-month free replacement warranty (FOB factory) and include a 120-month adjustment period from date of installation (USA only).
