UPS battery Extralink AGM 12V 7.2Ah (7Ah) Sealed Lead Acid VRLA, maintenance-free, black

Extralink AGM 12V 7.2Ah (listed 7Ah) sealed lead‑acid (VRLA) battery in a compact, maintenance‑free black housing. Designed as a single replacement or spare battery for UPS units, emergency lighting, small telecom equipment and other devices requiring a reliable 12 V rechargeable source. The valve‑regulated construction prevents gas release under normal conditions, enabling safe, leak‑free operation and flexible installation without special ventilation requirements.

Advantages

The battery uses AGM (Absorbent Glass Mat) VRLA technology that keeps the electrolyte immobilized for minimal maintenance and reduced leakage risk. Its sealed design allows installation in multiple orientations and limits corrosion in the installation area. With a nominal 12 V output and practical 7–7.2 Ah capacity it offers a compact backup solution for low‑to‑moderate power draw applications. The black, robust housing provides mechanical protection suitable for rack, cabinet or standalone placement.

Suitable for

• Uninterruptible power supplies (UPS) for home or small office
• Emergency lighting and alarm systems
• Small telecom and network devices (modems, routers, VOIP gateways)
• Portable instruments and backup power modules

How to use

Install the battery according to the UPS or device manufacturer's instructions, observing correct polarity and secure terminal connections. Charge the battery before first use using a compatible 12 V battery charger or the device's built‑in charging circuit. For long‑term storage, keep the battery at a partial charge (around 40–60%) and recharge periodically to prevent deep discharge. Do not open, puncture or expose the sealed unit to flames or high temperatures.

Usage recommendations

For reliable performance, pair the Extralink 12 V 7.2Ah battery with devices designed for VRLA/AGM batteries, maintain proper charging voltage and avoid deep discharges. Replace batteries in UPS systems in matched sets when required and dispose of the battery at an appropriate recycling facility at end of life.
