# RITAR RA batteries > Ritar RA solar gel batteries, 12V 50-250 Ah, deep cycle for off-grid solar systems. Sealed, maintenance-free, built for daily cycling. 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/batteries-ritar-ra - **Language**: en-GB ## Description **Ritar RA batteries** are 12V **solar GEL batteries**, from 50 to 250 Ah, designed for long-life off-grid photovoltaic installations. Their gelled electrolyte withstands daily **deep cycling** far better than a conventional starter battery. They are the **stationary battery for solar panels** built for country houses, water pumping, rural telecom and stand-alone systems that charge and discharge every day. Sealed, **maintenance-free** and with very low self-discharge — ideal where nobody is around to check water levels. ## Deep-cycle solar gel batteries for off-grid systems The **Ritar RA** series uses **GEL** electrolyte, which distributes the acid evenly and prevents stratification: the battery tolerates **repeated deep discharges** and slow recoveries — everyday life in an off-grid solar installation. Compared with a starter battery or a standard AGM, a **solar gel battery** keeps its capacity over many more daily working cycles. Being **sealed maintenance-free VRLA**, there is no water to top up and no special venting required — key for remote sites visited only a few times a year. ### Models in the Ritar RA series - **RA12-50** — 12V 50 Ah, for solar lighting, signalling and small loads. - **RA12-100** — 12V 100 Ah, the best-selling format for weekend solar kits. - **RA12-150** — 12V 150 Ah, for off-grid homes with moderate consumption. - **RA12-250** — 12V 250 Ah, for 24/48V banks and high daily loads. ### How to choose your solar gel battery Size the capacity from your daily consumption (Wh) and limit the routine depth of discharge: the less you discharge each cycle, the more years the bank will last. Our [battery comparison tool](/gb/comparator) lets you compare capacity, size and price across the whole RA range. ## Frequently asked questions about Ritar RA batteries ### **What is the difference between a GEL and an AGM solar battery?** GEL copes better with daily deep cycling and prolonged discharges, so it is preferred in off-grid solar installations; AGM delivers more instant power and is more common in UPS-style backup. ### **How long does a gel battery last in a solar installation?** It depends mainly on the daily depth of discharge and the temperature. With moderate discharges and properly regulated solar charging, a deep-cycle gel battery delivers far more cycles than a conventional battery. ### **Do Ritar RA batteries need maintenance?** No. They are sealed VRLA gel batteries: no water topping-up or level checks, just a charge controller correctly configured with a GEL profile. ### **Can I connect them in series for a 24 or 48V system?** Yes. Blocks of the same model, capacity and age can be wired in series to build 24 or 48V banks, as is standard in medium and large off-grid installations.
