Rolls Surrette Lead Acid Battery - 6V, 428Ah (S-550)
The Rolls Surrette S-550 deep cycle lead acid battery takes the L-16 format to new levels by improving overall capacity and service life. Though heavier than comparable L-16s, the S-550 is unsurpassed in reliability and offers 28 more amp-hours of capacity than the former S-530 it replaces. With a capacity of 428 amp-hours @ 20-hour rate (554 amp-hours @ 100-hour rate), this 6-volt flooded lead acid battery is great for demanding solar and other renewable energy applications. Connections are easy due to the thick lead alloy flag terminals for 5/16" bolts. It is packaged in a light weight structural molded container with lifting rope handles.
