Exide EK131 12V 13Ah 200A is an auxiliary battery: it supports the Start-Stop system and on-board electronics during stops, without draining the main battery.
Where it fits: the Exide EK131 is one of our auxiliary batteries, belongs to our Exide batteries and by capacity it sits among our 13Ah batteries.
Mostly to Mercedes-Benz Marco Polo Camper (1 orders with the vehicle identified). That those models use it does not guarantee it fits yours: check the plate, as tray and polarity vary by version.
The Exide EK131 with AGM technology is the 13 Ah, 12 V support battery for the auxiliary network of cars with advanced Start-Stop and heavy electronics. Its 150 × 90 × 145 mm and the positive terminal on the left make it the exact replacement for the 13 Ah battery fitted as standard to many vehicles with an auxiliary battery.
In short: the Exide EK131 (13 Ah, 200 A, 150 × 90 × 145 mm, positive terminal on the left). Verified equivalent alternatives: Tudor TK131 and Varta AUX14.
As an auxiliary battery, the Exide EK131 works alongside the main one; replace it when the vehicle reports a fault in the support network. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 4.50 kg.
In terms of format, the Exide EK131 measures 150 × 90 × 145 mm (length × width × height) and weighs 4.50 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Within the Exide catalogue, the Auxiliar series groups the references designed for this use. The EK131 is the 13 Ah model of that family, with the same performance as its siblings in other sizes.
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.
The auxiliary battery works alongside the main one: if a support-network fault warning appears, check both. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
The Exide EK131 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
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.

Fitting it yourself? Step-by-step guide to replacing the battery →
Yes. The Exide EK131 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. It is also required in cars with advanced Start-Stop and regenerative braking.
Yes: being AGM, the Exide EK131 is designed for Start-Stop cars. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the car manufacturer requires. It needs nothing to work, though on most modern cars registering it via OBD is advisable so the alternator adjusts its charging profile.
As a guide, you can expect the Exide EK131 to last 5 to 8 years in mild-climate car use with Start-Stop, although the real figure may be higher or lower. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count.
Its dimensions are 150×90×145 mm, also written 150x90x145 mm; the height already includes the terminals. Check the room available in your car, because a single millimetre too much can stop the clamp from closing.
On the Exide EK131, the polarity is positive on the left. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring.
The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the car manufacturer states in the owner's handbook.
See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the EK131, 13 Ah (200 A cranking).
It is the verified Varta equivalent for the EK131 tray. Compared with the EK131 it has the same Ah and cranking power. It costs 8,00 € more. Decide by price, brand preference and availability: both fit and crank the same.
The Tudor alternative that fits where the EK131 goes, with the same polarity. Compared with the EK131 it has the same Ah and cranking power. It costs 1,40 € more. A straight swap with nothing to adapt; the difference is the price and the brand you prefer.
In an AGM (Absorbent Glass Mat) battery the electrolyte is held in a glass-fibre mat: no spills, and many more charge/discharge cycles than a conventional battery. Compared with an EFB it resists tilted positions, heavy vibration and extreme temperatures better, and it is the recommended option where there is regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). The Exide EK131 has a capacity of 13 Ah.
It is not strictly necessary on most cars, because the alternator detects the change and adapts the charge. The advisable step is to register it via OBD: the charging profile is optimum from the first minute and the battery lasts longer, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). Without registration there is no starting problem: the alternator adjusts the profile within a few days. Any garage with an OBD scanner can do it in a few minutes. If you prefer to do it yourself: VCDS / Carista (VAG), Bimmercode (BMW) or iCarsoft.
