Sealed Lead Acid (VRLA) battery MPL Power MB 120-12 12 V 120 Ah, 35.5 kg, 174×233 mm

MPL Power MB 120-12 is a sealed lead-acid (VRLA) rechargeable battery with a nominal voltage of 12 V and a rated capacity of 120 Ah. The battery uses AGM (absorbed glass mat) technology in a dry, maintenance-free construction suitable for stationary backup power applications. With compact dimensions of 174 × 233 mm (width × height) and a weight of 35.5 kg, this unit is intended for UPS systems, telecom cabinets and other installations where reliable buffer power and safe indoor operation are required.

Advantages

The VRLA AGM design eliminates the need for electrolyte refilling and routine maintenance while minimizing gas emission under normal operation, which allows installation in rooms with people. Standardized dimensions and a sealed housing simplify mounting in racks or enclosures. The battery delivers a stable 12 V output and high 120 Ah capacity for extended standby periods and controlled discharge behaviour suitable for cyclic or float applications.

Suitable for

• Uninterruptible power supply (UPS) systems
• Telecommunications racks and base stations
• Stationary energy storage and backup power for equipment
• Emergency lighting and security systems
• Industrial control panels and monitoring devices

How to use

Install the MPL Power MB 120-12 in a suitable enclosure or rack designed for sealed lead-acid batteries. Ensure terminal connections are tight and correct polarity is observed. Use an appropriate charger and charge regime compatible with VRLA/AGM batteries; follow recommended float and cycle charge voltages from the system or charger manufacturer. Allow the battery to reach room temperature before charging if it has been stored in cold conditions. Do not open the sealed housing or attempt to service the internal cells.

Usage recommendations

For optimal lifetime and safety, operate the battery within the manufacturer-recommended temperature range and avoid deep discharges when possible. Use a charger with automatic voltage regulation and temperature compensation if available, perform periodic capacity checks in backup systems, and recycle the battery according to local regulations at end of life.
