VOLTAGE AGM Long Life Battery 12V 18Ah VEL12-18

The VOLTAGE VEL12-18 is a high-quality AGM (Absorbent Glass Mat) VRLA battery designed for long-life applications. With a nominal voltage of 12V and a capacity of 18Ah (C20), this maintenance-free battery offers exceptional reliability and a design life of up to 15 years. It is ideal for use in UPS systems, alarm systems, emergency lighting, telecommunications, solar power, and medical equipment.

Advantages

This battery features AGM technology, which ensures low internal resistance, high discharge rates, and excellent cycle stability. The immobilized electrolyte makes it spill-proof and safe for use in various orientations. With a self-discharge rate of less than 3% per month, it retains charge longer when not in use.
