AGM Green Cell Battery 12V 14Ah

Green Cell AGM08 – AGM Battery 12V 14Ah VRLA

Maintenance-free AGM battery with 12V voltage and 14Ah capacity, designed for both cyclic and standby (buffer) applications. Absorbent Glass Mat (AGM) technology ensures leak-proof operation, safety, and versatility across various backup power systems and mobile devices.

Product Description

The Green Cell AGM08 is a maintenance-free battery based on AGM (Absorbent Glass Mat) technology, where the electrolyte is absorbed into fiberglass separators. This makes the battery completely sealed and safe to use — it can operate in any position without the risk of leakage. It is designed for both standby (buffer) operation — continuous connection to a power source as backup — and cyclic use involving frequent charge and discharge. Its projected service life exceeds 5 years in standby mode, and it offers high resistance to deep discharges. The robust casing provides resistance to mechanical shocks, and Faston 250 (F2) terminals enable easy integration with a wide range of devices.

Key Features

• AGM technology – electrolyte absorbed in fiberglass separators
• Maintenance-free operation – no need to refill electrolyte
• Sealed construction – safe operation in any position
• High resistance to vibrations and mechanical impact
• Suitable for both cyclic and standby use
• Projected service life over 5 years (standby mode)
