📋 What we found
For your WET JET All All Models we found 5 compatible batteries. This list includes 3 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 WET JET All All Models 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
- WET JET All All Models: depending on the equipment, it takes a conventional 19 Ah, 240 A battery (176 × 101 × 156 mm) or a 18 Ah, 250 A AGM battery (177 × 88 × 156 mm). Measure your current battery before choosing. In every case the positive terminal is on the left. We found 5 compatible batteries priced between 72,40€ — 149,20€. Check dimensions and positive terminal position before purchasing.
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your WET JET All All Models battery compartment and the positive terminal position matches.
- Yes, we detected Start-Stop compatible batteries for your WET JET All All Models. If your vehicle has Start-Stop, it needs an AGM or EFB battery. An AGM must always be replaced with AGM. An EFB can be replaced with EFB or AGM. Never install a conventional battery in a Start-Stop vehicle.
- 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.
