Its 229 × 138 × 235 mm make it the exact replacement for the 58 Ah battery fitted as standard to many motorhomes and caravans. - Direct replacement for the original leisure battery. - Recharges from the alternator, a solar panel or a mains charger. - Withstands daily discharges throughout the season. - AGM: faster recharging and better cycle resistance than a conventional battery. ### Will it fit your current battery tray? In terms of format, the Ritar RA12-55A measures 229 × 138 × 235 mm (length × width × height) and weighs 15.50 kg. It uses M6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Ritar RA12-55A is for The Ritar RA12-55A is designed for motorhomes, caravans and campers that need power off-grid: it powers fridge, lights, pump and chargers for several days off-grid. Its 58 Ah capacity sets the available autonomy. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 15.50 kg and M6 terminals. ### The Ritar RA12-55A: RA range and AGM technology The **RA** is the Ritar range the RA12-55A belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### What Ritar does differently Ritar is one of the world's largest VRLA battery manufacturers. Its RA, RT, RL, HR and FT series equip UPS, telecoms and solar systems worldwide with very consistent quality. All the Ritar batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Ritar RA12-55A comes with the **manufacturer's official warranty** against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered. ### How to make it last longer Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### When you get it and how to return it Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is the Ritar RA12-55A an AGM battery and what are the benefits of AGM? Yes. The RA12-55A from Ritar uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for caravans with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How much energy does this battery give a caravan? It stores about 696 Wh. To make it last, it should not be discharged below half, so you have about 348 Wh usable: for example, an average load of 50 W for about 7 hours. ### Can it be charged with solar panels? Yes, with a charge controller (PWM or MPPT) set for AGM. It can also be charged by the vehicle alternator (ideally with a DC-DC charger) and by the 230 V charger when you are on hook-up at the campsite. ### What are the measurements of the RA12-55A model? Dimensions (length × width × height) are 229×138×235 mm — also written as 229x138x235 mm — following the European DIN standard. Always measure the space in your caravan before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-31*
