12V Sealed Rechargeable Deep Cycle Battery

2. Short Description

The Mercury Elite 26Ah 12V Deep Cycle Battery is a sealed, maintenance-free rechargeable battery designed for backup power, UPS systems, emergency lighting and other DC power applications.

Featuring 12V nominal voltage, 26Ah capacity and Absorbent Glass Mat (AGM) technology, this battery provides reliable energy storage in a compact, durable design.

Suitable for compatible backup power systems, telecommunications equipment and other applications requiring a 12V battery.

3. Product Description

The Mercury Elite 26Ah 12V Deep Cycle Battery is a sealed rechargeable battery designed to provide dependable backup power for electronic equipment and electrical systems.

Built with AGM (Absorbent Glass Mat) technology, the battery uses an internal electrolyte absorption system that helps prevent free-flowing liquid electrolyte under normal operating conditions.

Its 26Ah rated capacity makes it suitable for smaller backup power applications, including UPS systems, emergency lighting, telecommunications equipment and DC power systems.

The battery features a maintenance-free design, low self-discharge characteristics and a durable ABS plastic casing.

Whether used for backup power or other compatible DC applications, the Mercury Elite 26 offers a practical energy-storage solution.

Important: This is a sealed lead-acid battery, not a lithium battery. Confirm the charging requirements and compatibility with your equipment before installation.

7. Battery Energy Capacity

The battery's nominal energy capacity is:

12V × 26Ah = 312Wh

This is the nominal stored energy, not the guaranteed usable energy.

Actual usable capacity depends on discharge current, battery condition, temperature and the permitted depth of discharge.

For longer battery life, avoid frequent deep discharges and use a charger configured for sealed AGM batteries.
