Surette (Rolls in the USA) are very good batteries (perhaps the best wet batteries out there) with longer than average life (and higher than average prices to match) and you shouldn't be in a hurry to replace them unless you are sure they have been damaged.
Ken H. Established in 1935, Surrette Battery Company Limited is proud to be one of North America’s leading lead-acid battery producers and Canada’s only remaining independent battery manufacturer. Located in Springhill, Nova Scotia, we produce a wide range of Rolls-branded premium deep cycle batteries for use in Renewable Energy, Marine, Motive Power and Railroad applications.
