It measures 260 × 169 × 235 mm, the format sought by anyone replacing a 85 Ah battery in motorhomes and caravans. - Low self-discharge during months of storage. - Sealed and gas-free: suitable for installation inside the living area. - Power for fridge, lighting, water pump and USB off-grid. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### What the Ritar RA12-80S is for With 85 Ah, the Ritar RA12-80S is the habitation battery for motorhomes, caravans and campers that need power off-grid. It recharges from the alternator, a solar panel or a mains charger. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 22 kg and M6 terminals. ### The Ritar RA12-80S: RA range and AGM technology Within the Ritar catalogue, the **RA** series groups the references designed for this use. The RA12-80S is the 85 Ah model of that family, with the same performance as its siblings in other sizes. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Will it fit your current battery tray? The Ritar RA12-80S is made in the 260 × 169 × 235 mm format and weighs 22 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. ### Ritar: the maker behind the RA12-80S With more than twenty years making sealed lead batteries, Ritar offers general-purpose, long-life, high-rate and front-terminal ranges for every stationary application. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### How to make it last longer Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip. ### Warranty and coverage The Ritar RA12-80S comes with the **manufacturer's official warranty** against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered. ### Shipping, delivery and returns Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 RA12-80S model AGM? What does this technology offer? Yes. The RA12-80S 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 is the Ritar RA12-80S battery installed in the vehicle? In most caravans it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On caravans with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Ritar RA12-80S battery last? Expected lifespan of the Ritar RA12-80S is 5 to 8 years in mild-climate caravan use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the RA12-80S model? Dimensions (length × width × height) are 260×169×235 mm — also written as 260x169x235 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. ### Will the Ritar RA12-80S battery fit my caravan? Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The RA12-80S typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop caravans. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [RITAR RA12-70S](https://baterias.com/gb/battery-ritar-ra12-70s-12v-75ah-ra-agm) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-15*
