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 6:00 pm 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 14 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 much energy does this battery give a caravan?
It stores about 1,836 Wh. To make it last, it should not be discharged below half, so you have about 918 Wh usable: for example, an average load of 50 W for about 18 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 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.
Ritar RA12-145 or Ritar RA12-134: which one to choose?
It has the same dimensions, voltage and technology as the RA12-145, although it is not a manufacturer-approved equivalent. Compared with the RA12-145 it has 11 Ah less. It costs 42,75 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
