VRLA Battery

Dongjin valve-regulated lead-acid battery (VRLA battery) is also called sealed lead-acid (SLA) or maintenance free battery. There are 2 types of VRLA batteries from Dongjin Group: absorbent glass mat (AGM) and gel cell. The gel batteries and AGM batteries of VRLA can be mounted in any orientation, and do not require constant maintenance. A VRLA battery utilizes a one-way, pressure-relief valve system to achieve a "recombination" technology.

Our development team combines the market's demand with design optimization, precision component selection, and state-of-the-art manufacturing process to produce the most cost-effective battery solution for today's various energy-related systems. Dongjin VRLA (Gel and AGM) products have the reputation of being the high-quality VRLA batteries.
