# RITAR RL batteries > Ritar RL Long Life AGM batteries, 12V 7-150 Ah, 10-12 year float service life. For UPS and critical installations. Maintenance-free VRLA. 24h delivery. **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [Ritar batteries](https://baterias.com/gb/batteries-ritar) - **Canonical URL**: https://baterias.com/gb/ritar-rl-batteries - **Language**: en-GB ## Description **Ritar RL batteries** are 12V **Long Life AGM batteries**, from 7 to 150 Ah, with a design life of **10-12 years in float service**. This is Ritar's long-life series: the same sealed VRLA technology, but built to last roughly twice as long as a standard stand-by AGM. They are intended for **UPS systems and critical installations** where replacing batteries is expensive or awkward: data centres, plant rooms, telecoms and security systems. A **long-life stationary battery** means fewer replacements, fewer maintenance visits and less risk of backup failure. ## Long Life AGM batteries: up to 10-12 years of float service The **Ritar RL** (Long Life) series uses grids and materials sized to resist corrosion over more years of float service. The result is a **design life of 10-12 years**, versus the much shorter replacement cycles of a conventional stand-by AGM. In installations with many batteries, stretching each replacement translates directly into lower cost and less downtime. Like any **sealed VRLA AGM battery**, it runs maintenance-free, with no water topping-up and low self-discharge, ready to sit on float next to the electronics it protects. ### Models in the Ritar RL series - **RL12-7** — 12V 7 Ah, for compact UPS units, alarms and security equipment. - **RL12-50** — 12V 50 Ah, for mid-size UPS and comms cabinets. - **RL12-100** — 12V 100 Ah, the usual block in 48V backup strings. - **RL12-150** — 12V 150 Ah, for long runtimes in critical installations. ### How to choose your long-life AGM battery Keep the capacity (Ah), dimensions and number of blocks your equipment requires, and weigh the cost per year of service, not just the purchase price. Our [battery comparison tool](/gb/comparator) lets you compare capacity, size and price across the whole RL range. ## Frequently asked questions about Ritar RL batteries ### **How long does a Ritar RL battery last?** Its design life is 10-12 years in float service. Real-world life depends on ambient temperature and discharge regime: sustained heat and frequent deep cycles shorten it. ### **What is the difference between the RL and RT series?** Both are sealed VRLA AGM batteries, but the RT is the standard stand-by range while the RL is the Long Life version, with a 10-12 year float design life that cuts down the number of replacements. ### **When is a long-life battery worth the extra cost?** Whenever replacing the battery is expensive: remote sites, large strings, data centres or critical equipment. Over the life of the installation, fewer replacements usually means a lower total cost. ### **Do they need maintenance?** No. They are valve-regulated sealed VRLA batteries: just keep the recommended float voltage and avoid continuously high temperatures.
