Product Features

Maintenance-Free Design

The sealed VRLA design eliminates the need for water or electrolyte top-ups, reducing maintenance effort and risk.

Leak-Proof AGM Technology

Absorbent Glass Mat (AGM) technology holds electrolyte securely in place, allowing safe operation in multiple positions.

High Performance

Delivers high currents on demand and recovers quickly from deep discharges, making it ideal for UPS and emergency applications.

Reliable and Safe

Equipped with a low-pressure safety vent that automatically releases excess gas and reseals, preventing explosion risks.

Compact and Durable

Constructed with flame-retardant ABS plastic, the battery fits most small UPS units and is built to withstand long-term use.

Wide Operating Range

Operates reliably in temperatures from -15°C to 50°C for discharge and 0°C to 40°C for charging.
