Home › Car batteries › Batteries by brand › Mercedes-Benz › A-Class The Mercedes A-Class battery is 12 V and, on the W177 (from 2018), is AGM as standard, around 60-80 Ah and 680-800 A depending on the engine : AGM on the A 180, A 200, A 220 and A 250 petrol and on the A 180 d and A 200 d diesel, all with Start-Stop, plus a 12 V auxiliary battery on the A 250e plug-in hybrid, which does not start the engine. The battery sits in the engine bay and, since it has a sensor on the terminal, the new one must be registered in the ECU .

Today, with no appointment Send us your number plate on WhatsApp and we’ll tell you the exact battery for your Mercedes A-Class and the price in minutes. Call now WhatsApp The Mercedes A-Class is one of the most common premium compacts on Málaga's roads, and plenty pass through the workshop: from the everyday A 180 petrol to the A 250e plug-in and the odd AMG. They all share one important thing: the W177 comes with AGM from the factory and a battery sensor on the terminal, so fitting the battery and closing the bonnet isn't enough — it has to be registered with the ECU so the car charges it correctly. We do it on the spot, without an appointment , at C/ La Orotava, 100, 29006 Málaga , and the registration is included. Which battery does the Mercedes A-Class take?

How to find out which one your A-Class needs Between engines and trim levels there are far too many combinations to guess. Give us the number plate on WhatsApp or at the shop and we'll tell you the Ah, CCA, technology, polarity and exact dimensions. A tip: on the W177 the battery is in the engine bay and has a sensor on the negative terminal ; if you see it, your A-Class manages charging actively and needs AGM plus registration of the new battery. As it's AGM as standard, you can move up to a higher-capacity AGM, but never down from AGM to EFB or a conventional battery .

Request a quote Signs the A-Class battery needs replacing - Slow cranking from cold, especially first thing in the morning in Málaga. - Start-Stop doesn't engage , or it does and the engine restarts by itself seconds later: the classic first warning on the W177. - Dashboard messages such as "Vehicle battery: consult workshop", or electrical glitches that come and go. - A recently replaced battery that was never registered with the ECU : the car keeps treating it as the old one, charges it badly and it lasts half as long. - On the A 250e plug-in , the car won't reach "READY" or even power up despite the high-voltage battery being charged: almost always the 12 V auxiliary. - More than 4 years old. In Málaga an AGM lasts 5-7 years on average and the coastal heat shortens that margin.
