Rolls Battery has been manufacturing deep cycle batteries in Nova Scotia, Canada since 1959. Before moving into their current location, they began manufacturing batteries in 1935. That’s over 80 years of experience in the deep cycle battery market. Their batteries are used in a wide range of industries including railroad, marine, industrial & commercial, motive, and renewable energy. The Rolls Surrette line of batteries is becoming well known in the solar field. With uncompromised quality and craftsmanship, long life, durability, and overall great performance, our customers could not be happier with their investment.
The Rolls batteries can be used for both off-grid and grid-tie systems with battery backup. When using the batteries for off-grid installations, be sure your system is properly designed to bring the battery bank to a full charge within the limited number of sunlight hours for your region. If the batteries are not fully charged on a regular basis, you run the risk of discharging the battery bank beyond the 50% limit. This is what leads to warped plates and reduced amp-hour capacity.
The S-550 fits into the popular L-16 group size and is a part of the Surrette 4000 series. It comes with rope handles and a high density polypropylene container. There is a total of 17 plates per cell, and a total of 3 cells. The separator thickness is 0.061 inches (2 mm), has glass mat insulation of 0.02 inches (1 mm), and reserve electrolyte of 2.25 inches (57 mm) above the lead plates. The total capacity of the battery is 428 amp-hours at the standard 20 hour rate. If you plan to use the battery in motive or marine applications, the cold cranking amps (CCA) is 1315, and the marine cranking amps (MCA) is 1645. The total reserve capacity at 25 Amps is 931 minutes.
