3CORE® AGM Battery 12V 7Ah — sealed and maintenance-free 3CORE® 12V 7Ah is a modern lead-acid battery using AGM (Absorbed Glass Mat) technology, where the electrolyte is absorbed into microscopic glass fiber mats. This ensures higher safety, lower self-discharge, and improved vibration resistance compared to conventional flooded batteries. It is fully sealed and maintenance-free. AGM Technology Sealed (no leaks) Maintenance-free Can be used in any position Easy replacement (T1, 4.75 mm) Main advantages Sealed housing — safe for indoor use, no leakage risk. Maintenance-free — no need to refill electrolyte. Flexible installation — works both vertically and horizontally. Easy replacement — standard T1 (4.75 mm) terminals. Extended lifespan — low self-discharge and high cycle durability. Vibration resistant — reliable operation even in demanding environments.

Safety: electrolyte absorbed in glass mats — no leaks, lower gas emission. Durability: lower self-discharge and longer cycle life. Strength: better tolerance to vibration and shocks. Flexibility: can be installed in any position. Maintenance-free: no electrolyte refilling needed. FAQ — Frequently Asked Questions Can I replace this battery myself? Yes. Just disconnect the old battery and connect the new one using T1 (4.75 mm) terminals. It only takes a few minutes. Is the battery suitable for indoor use? Yes, the sealed VRLA/AGM design makes it safe for indoor installations (e.g., alarm panels, UPS units). Which devices is this model most commonly used in? Security and fire systems, UPS, telecom equipment, emergency lighting, and electric bikes.
