The BlueStorm DS-Gel is a 12 V digital-screen intelligent gel storage battery from the Gel Energy Storage Deep Cycle series. It is a maintenance-free gel (VRLA) design carrying a built-in digital screen that shows real-time battery status and is built for repeated deep-discharge cycling in solar and energy-storage systems. The datasheet covers three 12 V capacities that share the same charging, temperature, and storage behaviour and differ mainly in capacity, size, and weight.

Key features

• The built-in digital screen shows real-time battery status.
• Maintenance-free gel (VRLA) electrolyte, deep-cycle rated
• Solar / energy-storage deep-cycle design for repeated discharge
• Capacity range of 100 / 150 / 210 Ah at the 10-hour rate (12 V)
• Low self-discharge: 65% residual capacity after 12 months storage (25°C)
• Certified to UL, CE, ISO 9001, ISO 14001 and OHSAS 18001
