## Frequently asked questions

### What battery does the Yamaha Aerox Aerox R 2012 use?

The Yamaha Aerox Aerox R 2012 may use different batteries depending on engine and equipment. We found 2 compatible batteries priced between 20,54€ — 98,13€. Check dimensions and positive terminal position before purchasing.

### Can I install a higher capacity battery in my Yamaha Aerox Aerox R 2012?

Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Yamaha Aerox Aerox R 2012 battery compartment and the positive terminal position matches.

### Does my Yamaha Aerox Aerox R 2012 need a Start-Stop battery?

Yes, we detected Start-Stop compatible batteries for your Yamaha Aerox Aerox R 2012. 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.

### What type of battery does my motorcycle need?

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.

### How do I know the polarity of my motorcycle battery?

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.

### Can I install my motorcycle battery myself?

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.

### How do I find the right battery for my 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.

### What warranty do the batteries have?

As they are consumable items, car batteries have a 2-year warranty, truck batteries a 1-year warranty, and all others (motorcycle batteries, cyclic batteries, etc.) a 6-month warranty. If a battery has a manufacturing defect, it will be replaced at no cost to the user.

### How long does it take for the battery to arrive?

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.

### What dimensions do the Yamaha Aerox Aerox R (2012) compatible batteries have?

Batteries compatible with the Yamaha Aerox Aerox R (2012) fall into the following categories, each with typical dimensions: Start-Stop starter battery: 114 × 71 × 86 mm (length × width × height). Conventional starter battery: 121 × 71 × 93 mm (length × width × height). Before buying, check the battery compartment size of your vehicle: a larger case will not fit even if the reference is technically compatible.

### Does your Yamaha Aerox Aerox R (2012) 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.

⚠ 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.

## Guides

### How to change the battery of the motorcycle Yamaha Aerox Aerox R

Guide to safely replace the battery of the Yamaha Aerox Aerox R. Estimated time: 10-20 minutes. Tools: 8-10 mm wrenches, 4-6 mm Allen keys or Torx depending on the model. Many bikes require removing the seat or a side panel to reach the battery. Check the manual for fully faired models or those with reverse polarity.

1. **Prepare the motorcycle** — Put the bike on the centre stand — or, failing that, the side stand — on flat, firm ground. Switch off the ignition, remove the key and wait a few minutes for the engine to cool.
2. **Locate the battery** — On most motorcycles the battery sits under the seat, behind a side panel or near the fuel tank. On cruisers and adventure bikes it may be under the tank or in a frame compartment. Check the owner's manual if you can't find it.
3. **Remove the seat or access panel** — Release the seat (usually unlocked with the ignition key) or undo the side-panel screws (4-6 mm Allen keys or Torx are common). Keep the fasteners in order so you don't lose any.
4. **Identify polarity and hold-down** — Find the positive terminal («+», red cable) and the negative («−», black cable). Warning: some motorcycles — especially classic Japanese models — use reverse polarity; always confirm the exact orientation before removing the battery. Check whether it is held by a strap, clamp or plate.
5. **Disconnect the negative terminal first** — Using an 8-10 mm wrench, loosen and disconnect the negative terminal. Move it far enough from the chassis and secure it so it can't touch accidentally while you work.
6. **Disconnect the positive terminal** — Remove the positive protective cap if present and disconnect that terminal. Move the cable aside carefully and shield the area to avoid short circuits.
7. **Remove the old battery** — Undo the strap or hold-down. Lift the battery out keeping it upright; it weighs 2-8 kg depending on type. If it is an old flooded battery, be extra careful not to spill acid.
8. **Install the new battery and connect the terminals** — Fit the new battery matching the original polarity. If it is an AGM delivered dry, follow the manufacturer's instructions to activate it with electrolyte before installing. Connect positive first, then negative, and tighten gently — don't overtorque, the screws can break.
9. **Refit panels and verify** — Reattach the panel and seat. Without holding the starter button for more than 5 seconds at a time, start the bike and check lights, indicators, horn and instrument cluster. Reset the clock and any lost settings.

### How to identify the battery polarity of the Yamaha Aerox Aerox R

Knowing your battery polarity (positive on the right or on the left) is the most important step before buying a replacement: connecting it the wrong way can damage the electronics. Estimated time: 2 minutes. Tools: eyes only — no tools required.

1. **Locate the battery** — Open the bonnet of the Yamaha Aerox Aerox R and find the battery. It is usually a rectangular block with two metal terminals (large screw heads) on top — one red or "+" and one black or "−".
2. **Identify the positive terminal** — The positive terminal (+) typically has a red cap, red sticker or cover, a raised "+" symbol on the casing, and/or a slightly larger diameter (19 mm vs 17 mm of the negative, in standard European batteries).
3. **Face the battery** — Look at the battery from the label side with the terminals near you — the edge with the terminals should face you, not the back.
4. **Determine polarity** — If the positive pole is on the RIGHT → choose a battery marked as "positive right". If it is on the LEFT → choose one marked as "positive left". (If the label of your current or new battery shows codes like 0, 1, 3 or 4: 0 and 4 are positive right; 1 and 3, positive left — 3 and 4 correspond to batteries with terminals on the narrow side.)
5. **Note the reference** — The label on top shows the reference (e.g. "A9", "TK960", "EA900"). Search for the exact model with that reference and the identified polarity — never change polarity without consulting the vehicle manufacturer.
