# Batteries for UPS / UPS > Stationary AGM and OPzV batteries for APC, Eaton, Riello, Salicru, Cyberpower, Schneider UPS. Q-battery, Ritar, MK Battery. 8-12 year float life. **Category:** [Start](https://baterias.com/gb/beginning?id=2) → [Batteries](https://baterias.com/gb/batteries?id=3) → [Stationary Batteries](https://baterias.com/gb/stationary-batteries?id=95) - **Canonical URL**: https://baterias.com/gb/batteries-for-sai-ups?id=96 - **Language**: en-GB ## Description **UPS batteries** for servers, telecom racks, alarm and security systems, medical equipment, fire panels and machinery that cannot tolerate even a brief outage. **Sealed stationary AGM** with long float life (10-12 years) or **OPzV gel** for harsh environments. ## 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. ### Leading UPS brands - Q-battery - [Ritar RT](/gb/batteries-ritar) - [MK Battery](/gb/batteries-mk) - Cyclon (stationary) ### How to compare before buying your UPS battery Use the [comparator](/gb/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.
