Rolls Surrette S12-290AGM-RE Battery

The Rolls Surrette S12-290AGM-RE (S12290AGMRE) Deep Cycle Battery features a high cycle life without the need for maintenance. The AGM technology (Absorbed Glass-Mat) keeps the electrolyte (Acid) contained in the glass mats allowing the S12-290AGM-RE (S12290AGMRE) to not expel any liquids even under severe overcharge. S12-290AGM-RE (S12290AGMRE) is a NON-Hazardous battery resulting in lower shipping costs and can also be shipped via air. AGM batteries have an extremely low internal resistance giving them a very low self-discharge rate.

The S12-290AGM-RE (S12290AGMRE) is a 12 volt battery with a capacity of 290 Amp Hrs. @ 100 Hr. rate or 260 Amp Hrs @ 20 Hr. rate. This is a BCI group size 8D battery. The terminals are M8 Flag. It is also avaiable in a dual terminal confirguration.
