Rolls Surrette S2-1275AGM-RE Battery

The Rolls Surrette S2-1275AGM-RE (S21275AGMRE) 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 S2-1275AGM-RE (S21275AGMRE) to not expel any liquids even under severe overcharge. S2-1275AGM-RE (S21275AGMRE) 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 S2-1275AGM-RE (S21275AGMRE) is a 2 volt battery with a capacity of 1275 Amp Hrs. @ 100 Hr. rate or 1150 Amp Hrs @ 20 Hr. rate. The terminals are M10 threaded inserts.

Warranty is 3 years free replacement for renewable energy applications.

For a single string of 1275 Amp Hrs. @100 Hr rate, you will need 6 of the S2-1275AGM-RE (S21275AGMRE) for a 12-volt system, 12 of the S2-1275AGM-RE (S21275AGMRE) for a 24-volt system and 24 of the S2-1275AGM-RE (S21275AGMRE) 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.

• Up to 15% Quicker & More Efficient Charging
• Enhanced PSOC Performance
• Higher Capacity (~5% additional usable capacity)
• Improved Cycle Life
