What battery does the Kawasaki 80 KFX 80 use?

The Kawasaki 80 KFX 80 may use different batteries depending on engine and equipment. We found 6 compatible batteries priced between 22,20€ — 43,95€. Check dimensions and positive terminal position before purchasing.

Can I install a higher capacity battery in my Kawasaki 80 KFX 80?

Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Kawasaki 80 KFX 80 battery compartment and the positive terminal position matches.

Does my Kawasaki 80 KFX 80 need a Start-Stop battery?

Yes, we detected Start-Stop compatible batteries for your Kawasaki 80 KFX 80. 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.

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 Kawasaki 80 KFX 80 compatible batteries have?

Batteries compatible with the Kawasaki 80 KFX 80 have the following dimensions: 113–115 × 70–71 × 105–106 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.

📋 What we found

For your Kawasaki 80 KFX 80 we found 6 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. If in doubt, choose the one with higher capacity: provided the size fits, it gives more headroom for cold starts and accessories.

⚡ Battery type for your vehicle

✓ Your Kawasaki 80 KFX 80 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.

📊 View AGM vs EFB vs Conventional — full comparison

Here are the key differences between the three starter battery technologies. AGM is the most advanced technology (and the priciest); EFB is the middle ground for basic Start-Stop; conventional (also called flooded lead-acid) is the classic choice for non-Start-Stop cars.

	AGM	EFB	Conventional
Charge cycles	Up to 3× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard)	~2× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard)	Designed for start + alternator, not for repeated cycles
Expected life	5-7 years under average use	4-5 years under average use	3-4 years under average use
Start-Stop compatible	✓ Yes, even advanced systems (regenerative braking)	✓ Yes, basic and mid-range Start-Stop	✗ No — degrades within months
Cold start	Excellent (higher CCA)	Very good	Adequate
Relative price	€€€ (highest)	€€ (mid)	€ (lowest)
Recommended for	Premium cars with advanced Start-Stop, many electrical accessories, heavy urban use	Mid-range Start-Stop cars, mixed city/motorway use	Non-Start-Stop cars, standard use, tight budget
Replacement rule	Replaces AGM and EFB; NEVER use EFB where AGM was original	Replaces EFB and conventional; does NOT replace AGM	Only conventional; not suitable for Start-Stop

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 Battery

Battery for start-stop vehicles. Also a strong choice for more cycles, better charge recovery and longer service life.

: Motorcycles can use GEL, AGM or conventional batteries. GEL is ideal for occasional use as it holds its charge well. AGM is the best choice for intensive use or high-powered bikes. Always verify the polarity before installing.
: Polarity indicates which side the positive terminal (+) is on. For motorcycles this is critical as some models have the positive on the left and others on the right. Check the label on your current battery or the owner's manual.
: Yes. First disconnect the negative cable (−), then the positive (+). When fitting the new battery, connect the positive (+) first, then the negative (−). Always respect the correct polarity.
: Batteries compatible with the Kawasaki 80 KFX 80 have the following dimensions: 113–115 × 70–71 × 105–106 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.
