Its 159 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 40.50 kg and M8 terminals. ### The Ritar RA12-150A: RA range and AGM technology Within the Ritar catalogue, the **RA** series groups the references designed for this use. The RA12-150A is the 159 Ah model of that family, with the same performance as its siblings in other sizes. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Size, terminals and hold-down of the Ritar RA12-150A The Ritar RA12-150A is made in the 483 × 170 × 240 mm format and weighs 40.50 kg. It uses M8 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### 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. We guarantee that every Ritar arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Manufacturer's warranty The Ritar RA12-150A 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, it is AGM. In an AGM battery such as the RA12-150A, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### How much energy does this battery give a caravan? It stores about 1,908 Wh. To make it last, it should not be discharged below half, so you have about 954 Wh usable: for example, an average load of 50 W for about 19 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 RA12-150A model? It measures 483×170×240 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Ritar RA12-150A or Ritar EV12-150: which one to choose? Same case and same technology as the RA12-150A: an alternative by size, not an official equivalent. Compared with the RA12-150A it has 9 Ah less. It costs 66,12 € 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
