Sealed Lead Acid Battery Green Cell AGM31

Green Cell AGM31 is a 12 V sealed lead-acid (VRLA) battery with 120 Ah capacity, built for marine and leisure applications as well as general standby and deep-cycle use. The battery uses AGM (absorbed glass mat) technology: the electrolyte is absorbed into a fiberglass separator which prevents leakage and allows operation in different orientations. The sealed design eliminates regular maintenance and reduces the risk of acid spills compared with conventional flooded lead-acid batteries.

Advantages

The AGM31 provides a maintenance-free sealed construction and improved safety due to immobilised electrolyte. AGM technology enables better resistance to vibration and allows installation in non-vertical positions. With a compact footprint (175 x 410 x 230 mm) and a robust 33.5 kg build, the battery suits applications that require reliable, long-lasting power without regular servicing.

Suitable for

• Marine boats and yachts (house batteries)
• Leisure vehicles and camper vans
• Standby power for small UPS systems and telecom equipment
• Deep-cycle applications requiring long discharge/charge cycles
