How to choose the right UPS battery

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.

How to compare before buying your UPS battery

Use the comparator to check capacity (Ah), voltage, technology and dimensions of each model at a glance, and pick a battery that matches the format and runtime your UPS requires.

Frequently asked questions about UPS batteries

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.
