Sealed **maintenance-free VRLA** technology, mountable in any usual working position and ready for years on float. ## Stand-by AGM batteries for UPS, alarms and emergency systems The **Ritar RT** series is the general-purpose stand-by range: **sealed VRLA AGM batteries** that stay charged on float and deliver their energy when the mains fails. These are the batteries you find inside a **home or office UPS**, an alarm panel, an **emergency lighting** unit, an automatic gate or a kids' electric ride-on. Being sealed and valve-regulated they release no liquids and require no maintenance, so they can work inside closed enclosures right next to the electronics. ### Models in the Ritar RT series - **RT1213** — 12V 1.3 Ah, for compact electronics and security systems. - **RT1270** — 12V 7 Ah, the universal replacement for home UPS and alarm panels. - **RT12170** — 12V 17 Ah, for longer-runtime UPS, mobility and emergency units. - **RT12100** — 12V 100 Ah, for higher-capacity stationary backup. ### How to choose your replacement AGM battery Copy the data from the installed battery: voltage (12V), capacity (Ah), dimensions and terminal type, then pick the equivalent RT model. Our [battery comparison tool](/gb/comparator) lets you check size, capacity and price across the whole RT range on one screen. ## Frequently asked questions about Ritar RT batteries ### **Which battery does a home UPS take?** Most home and office UPS units use one or two 12V 7-9 Ah AGM batteries, such as the Ritar RT1270. Before buying, check the capacity, dimensions and terminal type of the original battery. ### **Are Ritar RT batteries suitable for an alarm panel?** Yes. They are stand-by batteries designed to sit on float and power the panel during a mains outage. The 1.3 to 17 Ah formats cover most alarm panels and sounders. ### **How long does a UPS battery last and when should I replace it?** It depends on temperature and the number of discharges: sustained heat is what ages it most. When the runtime drops noticeably or the UPS reports a battery fault, it is time to replace it. ### **What is the difference between the RT and RL series?** Both are sealed stand-by VRLA AGM batteries; the RT is the standard range while the RL is the Long Life version, with a 10-12 year float design life for installations where replacement is costly.
