What the Ritar RA12-225B is for
The Ritar RA12-225B 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 238 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 63 kg and M8 terminals.
Will it fit your current battery tray?
The Ritar RA12-225B is made in the 522 × 240 × 240 mm format and weighs 63 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.
The Ritar RA12-225B: RA range and AGM technology
The RA is the Ritar range the RA12-225B 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.
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.
Why choose Ritar batteries
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 RA12-225B comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.
Care and maintenance
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. 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.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 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 RA12-225B model AGM? What does this technology offer?
Yes. The Ritar RA12-225B is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance.
How much energy does this battery give a caravan?
It stores about 2,856 Wh. To make it last, it should not be discharged below half, so you have about 1,428 Wh usable: for example, an average load of 50 W for about 29 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 RA12-225B model?
Length × width × height: 522x240x240 mm. Height is measured to the top of the terminals. Measure your caravan's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
