Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your BMW X6 xDrive 40 d we found 3 compatible batteries. This list includes 1 Start-Stop battery and 2 auxiliary batteries.

⚡ Starter or auxiliary battery

We detected an auxiliary battery among the compatible ones. The auxiliary is NOT your main car battery: it is a smaller secondary battery that powers sensitive electronics. Don't mix them up when buying. Usually what fails is the starter battery (the main one), but the auxiliary can also fail. If your vehicle shows intermittent electronic errors but starts fine, it may be the auxiliary; if cranking is weak, it is usually the starter battery.

✓ Your BMW X6 xDrive 40 d uses the Start-Stop system. Every battery shown is compatible — no conventional options to confuse you.

🔋 Technology (AGM / EFB)

✓ All Start-Stop batteries in the list are AGM — the most advanced technology. Perfect if your current battery was AGM or EFB: AGM always replaces both. Remember to register it via OBD if your car has a BMS (BMW, Audi, VAG, Mercedes…) so the alternator charges it correctly.

Frequently asked questions

Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your BMW X6 xDrive 40 d battery compartment and the positive terminal position matches.
The Bmw X6 Xdrive 40 D requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 95 Ah, 850 A (CCA), 12 V, case H8/L5, Start-Stop (EFB/AGM) technology. Browse the compatible battery list below.
The exact Ah rating for the Bmw X6 Xdrive 40 D depends on the vehicle's original electrical consumers. Compatible batteries offer 95 Ah, 850 A (CCA), 12 V, case H8/L5, Start-Stop (EFB/AGM) technology. Use our finder for a precise recommendation.
To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.
Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
In mainland Spain and Portugal delivery takes 24 working hours if you order before 6:00 pm and the battery is in stock; for the Balearic Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.

Guides

This vehicle uses an AGM or EFB Start-Stop battery: after any replacement it must be registered via OBD so the BMS applies the correct charging profile. Without this step, the battery service life could be significantly reduced; on some vehicles (BMW, Audi, VAG, Mercedes) the alternator may stop charging it altogether.
