Voltage Long Life AGM Battery 12V 45Ah VEL12-45 (15-Year Design Life)

The Voltage Long Life AGM Battery VEL12-45 is a high-performance, maintenance-free power solution designed for critical standby and cyclic applications. With a nominal voltage of 12V and a capacity of 45Ah (C20), this VRLA battery delivers reliable energy storage for UPS systems, telecommunications, solar power, emergency lighting, security systems, medical equipment, and more. Its advanced AGM technology ensures sealed construction, low self-discharge, and a design life of 15 years at 20°C, making it an ideal choice for long-term backup power.

Advantages

This battery offers exceptional longevity and reliability. The AGM construction immobilizes the electrolyte in a glass mat, providing spill-proof operation and allowing installation in any position except inverted. It features explosion-proof pressure relief valves for safety, and its low self-discharge rate (approx. 3% per month at 20°C) ensures readiness even after extended storage. The battery is also compatible with float and cyclic charging, with recommended voltages of 13.5-13.8V (float) and 14.4-14.7V (cycle) at 25°C.

Suitable for

• UPS (Uninterruptible Power Supplies)
