## Summary description

Sealed AGM rechargeable battery Voltage VE12-120 with 12V nominal voltage and 120Ah capacity. Maintenance-free lead‑acid design suited for stationary power, backup systems, solar storage, and telecom applications. Provides long service life of approximately 6–9 years and stable performance in cyclic and standby use. Suitable for UPS, alarm systems and DC power installations.

## Long description

The Voltage VE12-120 is a sealed AGM rechargeable battery with a nominal voltage of 12 V and a rated capacity of 120 Ah. Designed as a maintenance-free lead‑acid unit, it delivers stable performance for both cyclic and standby applications. The construction uses absorbed glass mat (AGM) technology to minimise self-discharge and eliminate the need for regular electrolyte checks. With an expected service life of approximately 6–9 years, this battery is intended for stationary power, backup systems and DC installations where reliable energy storage and predictable discharge behaviour are required.
Advantages
The sealed AGM design provides leak-free operation and reduced off-gassing compared with flooded batteries, enabling installation in confined indoor environments. High rated capacity and low self-discharge offer consistent backup runtime for UPS, alarm and telecom equipment. The battery is maintenance-free, requiring no topping-up of electrolyte, and its lead‑acid chemistry supports both cyclic and standby regimes with predictable ageing over the stated service life.
Suitable for
Uninterruptible power supplies (UPS) for servers and network equipment
Stationary backup systems for residential and commercial premises
Solar energy storage in small to medium installations
Alarm and security systems
Telecom and DC power cabinets

How to use
Install the battery in a well-ventilated, dry location and secure it in the battery compartment or rack according to the equipment manufacturer’s instructions. Observe correct polarity when connecting to inverters, chargers or UPS devices. Use a compatible charger or charging profile for sealed AGM lead‑acid batteries; avoid overcharging and prolonged deep discharge to maximise service life. Periodically inspect terminals and connections for corrosion and ensure tight, clean contacts. Follow local regulations for battery handling and disposal.
Usage recommendations
For optimal longevity, charge the battery shortly after discharge and maintain float charge within manufacturer-recommended voltage ranges for AGM batteries. Prevent sustained temperatures above recommended operating limits and avoid repeated deep cycling without appropriate reconditioning. Store the battery at a partial state of charge if not in use and recharge every few months to limit capacity loss.
