Rolls Surrette S12-380AGM 12V 300Ah Deep-Cycle AGM Battery

The Rolls Surrette S12-380AGM is a heavy-duty 12V 300 Ah deep-cycle battery built in a large 8D size for off-grid solar power systems. It uses advanced Nano-Carbon Active Material (NAM) on its battery plates, which helps it charge faster and run more efficiently when your solar panels do not get full sunlight.

Its heavy-duty plastic case features strong rope handles for lifting and a sealed, leak-proof design that never needs water added. With very low power loss when sitting unused and sturdy L-shaped terminals for heavy copper wires, this battery provides long-lasting backup energy for houses, cabins, and commercial power setups.
