Battery analysis for your BMW 1 120 d
Quick answer Depending on the equipment, your car uses one of these two main batteries. The most common option is AGM 80 Ah (315×175×190 mm): we recommend VARTA A6. Other units use Lead-acid 80 Ah (315×175×175 mm): VARTA F17. Before buying, check the Ah on your current battery's label or measure its length.

📋 What we found
For your BMW 1 120 d we found 4 compatible batteries. This list includes 2 Start-Stop batteries and 2 conventional batteries (non Start-Stop).
📏 Battery size
The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.
⚡ Battery type for your vehicle
Does your BMW 1 120 d have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.
How do I know if my car has Start-Stop?
What happens if I fit a conventional battery in a Start-Stop car?
🔋 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.

Start-Stop & high energy demand batteries
AGM or EFB battery for start-stop vehicles and for cars with high energy demand (many electrical consumers, frequent starts). More charge cycles, better charge recovery and longer service life.
Does your car have Start-Stop?
Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.
There are no batteries of that type for this engine. Try "Show all" or message us.

Frequently asked questions
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your BMW 1 120 d battery compartment and the positive terminal position matches.
- The Bmw 1 120 D requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 80-95 Ah, 740-850 A (CCA), 12 V, case T7/LB4, conventional flooded and Start-Stop (EFB/AGM) technology. Browse the compatible battery list below.
- The exact Ah rating for the Bmw 1 120 D depends on the vehicle's original electrical consumers. Compatible batteries offer 80-95 Ah, 740-850 A (CCA), 12 V, case T7/LB4, conventional flooded and Start-Stop (EFB/AGM) technology. Use our finder for a precise recommendation.
- With normal use, a battery for the Bmw 1 120 D lasts 3–5 years. A healthy alternator and avoiding deep discharges significantly extend battery life.
- 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.
- ⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop. 💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better. 💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.
