How long does a UPS battery last?

8-12 years on float charge at 25 °C. That's far longer than a cranking battery, because it stays at 100% charge and only discharges during actual outages.

Why does heat shorten UPS battery life?

Above 30 °C, service life halves for every extra 8-10 °C (the Arrhenius rule), so a well-ventilated or air-conditioned technical room significantly extends battery life.

Is it compatible with my APC, Eaton, Riello or Salicru UPS?

Yes. Most of these manufacturers use standard 12 V batteries of 7, 9, 12, 18, 26, 40, 65 or 100 Ah; just match the physical format and the minimum capacity stated by your UPS maker.

What's the difference between stationary AGM and OPzS/OPzV for a UPS?

Stationary AGM covers home and rack UPS units (7-150 Ah); data centres and industrial installations of 200-1,500 Ah use 2 V OPzS/OPzV cells wired in series.

How to choose the right UPS battery

UPS batteries float-charge: 100% topped up permanently, energy only delivered on outages. Stationary AGM is designed for that role — sulphates very slowly, 8-12 years float at 25 °C. Above 30 °C, life halves every 8-10 °C (Arrhenius rule).

Typical capacities by UPS size

UPS / application	Typical capacity	Battery voltage	Technology
Small home UPS	7-9 Ah	12 V	Stationary AGM
Rack 1-3 kVA	12-100 Ah	12 V	Stationary AGM
5-10 kVA UPS	50-150 Ah	12 V series	Stationary AGM
Data centre / industrial	200-1,500 Ah	2 V cells in series	OPzS / OPzV

UPS brand compatibility

Compatible with APC, Eaton, Riello, Salicru, Cyberpower, Schneider Electric, Vertiv, Liebert, MGE, Powerware, Tripp Lite. Most use standard 12 V formats of 7, 9, 12, 18, 26, 40, 65 or 100 Ah; simply match the physical format and the minimum capacity required by your UPS manufacturer.
