What the Ritar RA12-120S is for
The Ritar RA12-120S 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 116 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 29 kg and M8 terminals.
Size, terminals and hold-down of the Ritar RA12-120S
It has external dimensions of 328 × 172 × 222 mm and weighs 29 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 RA12-120S: RA range and AGM technology
Within the Ritar catalogue, the RA series groups the references designed for this use. The RA12-120S is the 116 Ah model of that family, with the same performance as its siblings in other sizes.
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.
Ritar: the maker behind the RA12-120S
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Manufacturer's warranty
The Ritar RA12-120S 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
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. Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip.

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe.

Frequently asked questions
Is the Ritar RA12-120S an AGM battery and what are the benefits of AGM?
Yes. The Ritar RA12-120S 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 1,392 Wh. To make it last, it should not be discharged below half, so you have about 696 Wh usable: for example, an average load of 50 W for about 14 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 RA12-120S model?
The Ritar RA12-120S takes up 328×172×222 mm (length, width and height, terminals included). Before buying, measure the space in your caravan: one extra millimetre can stop the hold-down clamp from closing.
Ritar RA12-120S or Ritar RA12-100A: which one to choose?
Same case and same technology as the RA12-120S: an alternative by size, not an official equivalent. Compared with the RA12-120S it has 10 Ah less. It costs €173.45 less. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
