Rolls Surrette S12-55AGM-RE Battery

The Rolls Surrette S12-55AGM-RE (S1255AGMRE) 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 S12-55AGM-RE (S1255AGMRE) to not expel any liquids even under severe overcharge. S12-55AGM-RE (S1255AGMRE) 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 S12-55AGM-RE (S1255AGMRE) is a 12 volt battery with a capacity of 58 Amp Hrs @ 20 Hr. rate. This is a BCI group size 22NF battery. The terminals are M6 threaded inserts.

Warranty is 3 years free replacement for renewabe energy applications.

For a single string of 58 Amp Hrs. @20 Hr rate, you will need 1 of the S12-55AGM-RE (S1255AGMRE) for a 12-volt system, 2 of the S12-55AGM-RE (S1255AGMRE) for a 24-volt system and 4 of the S12-55AGM-RE (S1255AGMRE) for a 48-volt system. Each additional string will multiply the Amp Hrs.

This product contains Rolls ADVANCED NAM carbon additive.

The addition of Advanced NAM carbon additive in Rolls premium heavy-duty negative plate structure increases overall charge acceptance, offering improvements of 10-15% in charge efficiency, requiring shorter charge times and improved performance in conditions of partial state of charge (PSOC) common experienced in off-grid solar applications.
