⚡ Battery type for your vehicle
Does your Gilera Runner Runner 125 VX 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.

Frequently asked questions
- Gilera Runner Runner 125 VX (14 hp): depending on the equipment, it takes a conventional 9 Ah, 85 A battery (136 × 76 × 139 mm) or a 9 Ah, 85 A AGM battery (135 × 75 × 140 mm). Measure your current battery before choosing. In every case the positive terminal is on the left. We found 6 compatible batteries priced between 33,80€ — 110,60€. 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 Gilera Runner Runner 125 VX battery compartment and the positive terminal position matches.
- Yes, we detected Start-Stop compatible batteries for your Gilera Runner Runner 125 VX. 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.
- Motorcycles can use GEL, AGM, or conventional batteries. GEL batteries are ideal for occasional use. AGM batteries are the best option for heavy use or high-power motorcycles. Always check the polarity before installation.
- Polarity indicates which side has the positive (+) terminal. This is critical for motorcycles because some models have the positive terminal on the left and others on the right. Check the label on your current battery or the manufacturer's manual.
- Yes. First disconnect the negative (−) wire and then the positive (+) wire. When installing the new one, connect the positive (+) wire first and then the negative (−) wire. Always respect the correct polarity.
- 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.
- ⚠ 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.
