## Description

**AGM Long Life battery**: long-life stand-by AGM for uninterruptible power supplies (UPS), with a 10-12 year float service life. 12V, from 7 to 200 Ah, covering everything from small office UPS units to larger critical installations.
It's the balanced choice when you need more longevity than a standard AGM without the cost of a premium pure lead range, ideal for UPS, alarms, emergency lighting, telecoms and other continuous float-duty installations where replacement costs matter.

## AGM Long Life: more years of service in your UPS

AGM Long Life is specifically designed for continuous float duty, the typical regime of a UPS: the battery stays fully charged and only delivers energy during a power cut. Its construction reaches 10 to 12 years of service life under these conditions, compared with the typical 3-5 years of a general-purpose AGM.

### AGM Long Life models and applications

- **LL12-7** (7 Ah) — desktop UPS and office equipment.
- **LL12-50** (50 Ah) — server room UPS and electrical panels.
- **LL12-100** (100 Ah) — medium-power critical installations.
- **LL12-200** (200 Ah) — high-power UPS and telecommunications.

### How to choose your AGM Long Life

Work out the capacity (Ah) based on the autonomy you need during a power cut and your UPS's power rating; every reference shares the same long-life stand-by technology. Compare models with our [battery comparator](/gb/comparator).

## Frequently asked questions about the AGM Long Life battery
