The Amp-Tech AT1245 is a compact, general-purpose 12V 4.5Ah VRLA/AGM (Absorbent Glass Mat) maintenance-free battery. Manufactured by SuperCharge, it is engineered using advanced oxygen recombination technology and specialized grid alloys to minimize gassing, lower self-discharge rates, and extend shelf life.
Featuring a durable, high-impact ABS plastic container with an anti-vibration design, this battery is built to deliver steady, reliable, low-level power output. It is commonly deployed in security systems, alarm backup panels, emergency exit lighting, UPS devices, toy ride-ons, and delicate electronic or medical instrumentation.

Core Design Advantages
-
Spill-Proof & Leak-Proof: AGM separator tech absorbs electrolyte safely, allowing safe installation in various orientations (excluding inverted).
-
Low Self-Discharge: Retains charge remarkably well during prolonged storage periods prior to initial use.
-
Vibration Dampening: Robust plate framing and structural paste layout prevent active-material shedding under physical movement or light shock.
