What battery does the Claas Challenger 45 use?

The Claas Challenger 45 may use different batteries depending on engine and equipment. We found 6 compatible batteries priced between 100,70€ — 494,50€. Check dimensions and positive terminal position before purchasing.

Can I install a higher capacity battery in my Claas Challenger 45?

Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Claas Challenger 45 battery compartment and the positive terminal position matches.

What battery does my tractor or agricultural machinery need?

Diesel agricultural machinery requires high-capacity (Ah) batteries with high cold cranking amps (CCA). Diesel engines are more difficult to start in winter. We recommend AGM batteries for heavy-duty use.

Why is CCA important in agricultural batteries?

Cold Cranking Amps (CCA) measures the current the battery can deliver to start the engine at -18°C. In diesel agricultural machinery, insufficient CCA means the engine won't start in winter. Always choose a CCA equal to or higher than the original rating.

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 capacity (Ah) should the Claas Challenger 45 battery have?

Batteries compatible with the Claas Challenger 45 have a capacity of 85 Ah. When choosing, respect your vehicle's original capacity: a lower capacity can cause cold-weather starts or accessory issues; a higher capacity fits if dimensions match and extends autonomy.

📋 What we found

For your Claas Challenger 45 we found 6 compatible conventional (non Start-Stop) batteries.

⚡ Battery type for your vehicle

✓ Your Claas Challenger 45 does not need a Start-Stop battery. The conventional ones shown fit your vehicle and are the most affordable option. If you want a higher-quality, longer-lasting battery, you can also fit an EFB or AGM as an upgrade — they are fully compatible and last more years.

📊 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

⭐ Our recommendation

Our recommendation

For your Claas Challenger 45 we recommend the VARTA H17 (PLOMO/ACIDO, 105 Ah). It also offers the highest capacity (Ah) and the highest cranking power (CCA) on the list — more headroom in cold starts and with many consumers. Varta is the world's leading manufacturer of starter batteries and supplies first-equipment (OEM) batteries to the major European car makers.

Rated 4.8/5 by 60 verified customers.

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.
