Designed to power the entire interior kit (fridge, heater, water pump, USB, LED lighting) for several days off-grid, with no need to plug into a campsite hookup. ### Why this caravan battery? - **Real off-grid autonomy** no campsite hookup needed - **Lasts the whole season** handles daily discharges without capacity loss - **Powers it all at once** fridge, water pump, LED and USB without issues 🔌 Voltage 12 V ⚡ Capacity 153 Ah C20 📏 Dimensions 340×173×285 mm ⚙️ Technology AGM ⚖️ Weight 41,5 kg 🏷️ Model RITAR RA ## Description ## Leisure battery Ritar RA12-145 RA 153Ah 12V 12*V* Voltage 153*Ah* Capacity 41.50*kg* Weight For motorhomes, caravans and campers that need power off-grid, the **Ritar RA12-145** from the **RA** range provides **153 Ah** of energy with AGM technology. It replaces the original battery without adaptation in motorhomes and caravans with a 340 × 173 × 285 mm format: same 153 Ah capacity. - Sealed and gas-free: suitable for installation inside the living area. - Low self-discharge during months of storage. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Power for fridge, lighting, water pump and USB off-grid. ### What the Ritar RA12-145 is for The Ritar RA12-145 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 153 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 41.50 kg and M8 terminals. ### Will it fit your current battery tray? In terms of format, the Ritar RA12-145 measures 340 × 173 × 285 mm (length × width × height) and weighs 41.50 kg. It uses M8 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 Ritar does differently 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 RA12-145: RA range and AGM technology The **RA** is the Ritar range the RA12-145 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. ### Usage and maintenance tips 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. ### Manufacturer's warranty The Ritar RA12-145 comes with the **manufacturer's official warranty** against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered. ### When you get it and how to return it 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 this battery AGM? What is it for? Yes. The RA12-145 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 fit the RA12-145 model in my caravan? 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 RA12-145 battery last? Expected lifespan of the Ritar RA12-145 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 RA12-145 battery? Dimensions (length × width × height) are 340×173×285 mm — also written as 340x173x285 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. ### Is the RA12-145 valid for my vehicle? 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 RA12-145 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Ritar RA12-145? 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. ## Reviews - **Average rating**: 4.87 / 5 (11 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 · 2026-10-02*
