It replaces the original battery without adaptation in motorhomes and caravans with a 195 × 130 × 180 mm format: same 35 Ah capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Power for fridge, lighting, water pump and USB off-grid. - Sealed and gas-free: suitable for installation inside the living area. - Low self-discharge during months of storage. ### What the Ritar RA12-33 is for As a leisure battery, the Ritar RA12-33 is discharged and recharged every travelling day; avoid discharges below 50% to extend its life. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 9.60 kg and M6 terminals. ### Will it fit your current battery tray? The Ritar RA12-33 is made in the 195 × 130 × 180 mm format and weighs 9.60 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 RA12-33 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. All the Ritar batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### The Ritar RA12-33: RA range and AGM technology The RA12-33 is part of the Ritar **RA** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Care and maintenance Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip. During months of storage, keep it charged with a mains charger or a small solar panel; a battery left discharged for weeks loses capacity permanently. ### Official warranty The Ritar RA12-33 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 Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the Ritar RA12-33 an AGM battery and what are the benefits of AGM? Yes. The RA12-33 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 do I change this battery step by step? 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 this page. 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 RA12-33 battery last? Expected lifespan of the Ritar RA12-33 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 dimensions of the Ritar RA12-33 battery? Dimensions (length × width × height) are 195×130×180 mm — also written as 195x130x180 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 RA12-33 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 RA12-33 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the RA12-33 model? 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 - [MK POWERED MU-1 SLD M-2](https://baterias.com/gb/battery-mk-mu-1-sld-m-2-agm-12v-35ah) ## Reviews - **Average rating**: 4.82 / 5 (31 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-30*
