📋 What we found

For your Yamaha 450 Yfm45Fx Wolverine we found 2 compatible Start-Stop batteries.

📏 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

✓ Your Yamaha 450 Yfm45Fx Wolverine 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.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — Start-Stop requires AGM or EFB)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.

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.

2 products

This engine comes with an AGM/EFB battery as standard: the car's charging system requires it even without Start-Stop. If in doubt, message us and we will confirm.
