6. Verdict: which Craftsman lawn mower battery should you choose?

The best Craftsman lawn mower battery for many riding mowers is the Mighty Max ML-U1, a 12V sealed lead-acid battery with 200 CCA. For more starting capacity, compare the MARXON 280 or 360 CCA U1 options, and consider lithium only after confirming your mower supports it.

A “Craftsman battery” can mean two different things: a 12V starter battery for a riding mower or a removable V20 pack for cordless outdoor equipment. These batteries aren't interchangeable, so identify the mower platform first.

Which Craftsman lawn mower battery is the best match?

The best match is the battery that meets your exact mower's voltage, group size, CCA requirement, dimensions and terminal polarity. The highest CCA rating isn't automatically the right choice if the case doesn't fit or the cables can't reach.

Our comparison focuses on the product details relevant to fit and starting: battery type, voltage, CCA, dimensions, polarity where stated, and whether a product is a starter battery or a V20 tool pack. The score weighs those details against the needs of a Craftsman mower owner.

Compare Craftsman replacement batteries by platform

A U1 battery is the relevant group for many riding mower starting systems, while the small 4L-BS formats apply only to equipment designed for that size. V20 batteries power a separate cordless platform.

Greenworks owners can compare replacement lawn mower batteries for their model.

These picks are ordered by score, but compatibility comes first. Use your mower manual and existing battery label to confirm the required group, voltage, CCA range, dimensions and terminal orientation.

1. Mighty Max Battery ML-U1 12V 200CCA Battery: Best for a 200 CCA U1 replacement

1

Mighty Max Battery ML-U1 12V 200CCA Battery: Best for a 200 CCA U1 replacement

9.7/10Our score

• 12V sealed lead-acid battery
• 200 CCA
• 7.62 x 5 x 7 in
• Positive terminal on left

A 12V U1 size option with 200 CCA and left-positive polarity. Check your mower's tray and cable layout against its dimensions before ordering.

See it on Amazon

Pros

• 200 CCA rating
• Spill-proof SLA/AGM design
• One-year warranty

Cons

• No wire harness or mounting accessories included

The Mighty Max ML-U1 is a straightforward candidate when your Craftsman calls for a 12V U1 battery close to its 200 CCA rating. Its case measures 7.62 x 5 x 7 inches, with positive polarity on the left and negative on the right.

The sealed lead-acid battery is rechargeable and described as spill proof. Mighty Max includes screws, but no wire harness or mounting accessories, so keep any reusable parts from your mower if the manual permits.

It carries a one-year warranty. Before buying, compare both the case measurements and the position of the mower's positive and negative cables with the battery layout.

2. MARXON U1 Riding Lawn Mower Batteries Garden: Best for a 280 CCA U1 match

2

MARXON U1 Riding Lawn Mower Batteries Garden: Best for a 280 CCA U1 match

9.6/10Our score

• 12V sealed lead-acid battery
• 280 CCA
• 7.68 x 4.92 x 6.14 in
• Positive terminal on left

This MARXON U1 battery pairs a 280 CCA rating with a compact case height. Verify the mower specifies a compatible U1 battery and polarity.

See it on Amazon

Pros

• 280 CCA
• Maintenance-free design
• 15-month warranty

Cons

• Battery and screws only

MARXON's U1 battery offers 280 CCA in a 12V sealed lead-acid case measuring 7.68 x 4.92 x 6.14 inches. Its positive terminal is on the left, and its maintenance-free design doesn't require adding acid or water.

The lower case height may help if your mower's battery tray has limited vertical clearance, but measure the available space and check the hold-down arrangement. MARXON provides a 15-month warranty.

This option is a fit candidate only when your Craftsman manual accepts a U1 battery with matching electrical requirements. Its included contents are the battery and screws.

3. MARXON U1 Riding Lawn Mower Battery: Best for a higher CCA U1 option

3

MARXON U1 Riding Lawn Mower Battery: Best for a higher CCA U1 option

9.4/10Our score

• 12V sealed lead-acid battery
• 360 CCA
• 7.68 x 4.92 x 6.14 in
• Positive terminal on left

A U1 option rated at 360 CCA, with dimensions and polarity stated for fit checks. Confirm your Craftsman model's required battery group and terminal orientation.

See it on Amazon

Pros

• 360 CCA rating
• Maintenance-free design
• 15-month warranty

Cons

• Battery and screws only

This MARXON U1 model has a 360 CCA rating and states compatibility with Craftsman 25780 and ZT7000 models, among other equipment. Its dimensions are 7.68 x 4.92 x 6.14 inches, with positive polarity on the left.

The maker describes a maintenance-free design and a 15-month warranty. As with any cross-model compatibility claim, verify your mower's exact model and battery requirements before choosing this replacement.

It uses a 12V sealed lead-acid design. The higher CCA rating can be useful only where the mower's specified battery group and electrical system support this battery.

4. WEIZE 12.8V 12Ah Lithium Battery for Lawn: Best for a lithium U1 replacement

4

WEIZE 12.8V 12Ah Lithium Battery for Lawn: Best for a lithium U1 replacement

9.3/10Our score

• 12.8V LiFePO4 battery
• 480 CCA
• BCI Group U1
• 5.84 lb stated battery weight

A Group U1 lithium option with 480 CCA and stated compatibility with Craftsman. Check your mower manual for lithium battery and charging-system suitability.

See it on Amazon

Pros

• 480 CCA rating
• Lighter than the listed lead-acid options
• Five-year warranty stated

Cons

• Requires checking lithium charging compatibility

WEIZE's BCI Group U1 LiFePO4 battery is described as compatible with Craftsman and is rated at 480 CCA. It measures 7.68 x 5.12 x 7.1 inches including the terminals, weighs about 5.8 lb according to the stated battery weight, and has positive polarity on the left.

Lithium chemistry makes charging compatibility an important check. Confirm the Craftsman mower's manual allows this battery type and that the charging system suits it before replacing a lead-acid battery.

WEIZE states a five-year warranty for this battery line. The battery is supplied on its own, so it isn't a cordless V20 pack or a complete mower kit.

5. UPLUS U1 Riding Lawn Mower Battery: Best for a 330 CCA U1 replacement

5

UPLUS U1 Riding Lawn Mower Battery: Best for a 330 CCA U1 replacement

9.2/10Our score

• 12V sealed lead-acid AGM
• 330 CCA
• 7.68 x 4.92 x 6.93 in
• Positive terminal on left

UPLUS gives a 330 CCA rating and names Craftsman among compatible brands. Match its case height and terminal direction to your mower.

See it on Amazon

Pros

• 330 CCA rating
• Maintenance-free AGM design
• 15-month warranty

Cons

• Confirm exact model compatibility before ordering

The UPLUS U1 is a 12V AGM lead-acid battery rated at 330 CCA. Its dimensions are 7.68 x 4.92 x 6.93 inches, and its positive terminal is on the left.

UPLUS names Craftsman among the compatible brands and describes the battery as maintenance free. Check your exact mower model and the vertical clearance beneath its battery cover, since this case is taller than the MARXON U1 options above.

The stated warranty is 15 months. Choose it when the mower calls for a compatible U1 battery and its dimensions and terminal position match your tray and cables.

6. Mighty Max Battery YTX4L-BS Replacement for Snapper: Best for a compact 4L-BS setup

Mighty Max Battery YTX4L-BS Replacement for Snapper: Best for a compact 4L-BS setup

8.9/10Our score

• 12V sealed lead-acid battery
• 3Ah capacity
• 50 CCA
• 4.4 x 2.9 x 3.42 in

This compact battery is described as a replacement for a Snapper walk-behind mower. Consider it for a Craftsman only if your manual specifies a matching 4L-BS size and electrical requirements.

See it on Amazon

Pros

• Compact dimensions
• Rechargeable SLA/AGM design
• One-year warranty

Cons

• Not a U1 battery

This Mighty Max battery is a 12V, 3Ah, 50 CCA SLA unit measuring 4.4 x 2.9 x 3.42 inches. It is described as a replacement for a Snapper walk-behind mower, with negative polarity on the left and positive on the right.

Its compact case is not a substitute for a U1 battery. Consider it for a Craftsman mower only if the manual or existing battery identifies the same 4L-BS format and electrical requirements.

Mighty Max includes screws and gives it a one-year warranty. The product information doesn't guarantee fit for Craftsman models, so use your mower's part number and battery label to confirm.

7. TYKOOL LFP4L-BS-STD 12V Lithium Battery: Best for a compatible small lithium setup

7

TYKOOL LFP4L-BS-STD 12V Lithium Battery: Best for a compatible small lithium setup

8.7/10Our score

• 12V lithium battery
• 140 CCA
• 3Ah capacity
• 4.44 x 2.7 x 3.34 in

A small-format lithium option described for lawn mower use. Its maker requires a qualified regulator below 15.0V and a dedicated LiFePO4 charger.

See it on Amazon

Pros

• 140 CCA rating
• Compact case
• Digital voltage readout

Cons

• Requires a compatible regulator and LiFePO4 charger

TYKOOL's LFP4L-BS-STD is a 12V lithium battery rated at 140 CCA and 3Ah, with a 4.44 x 2.7 x 3.34 inch case. It is a small-format option, not a U1 riding mower battery.

TYKOOL requires a qualified regulator with output below 15.0V and a dedicated LiFePO4 charger. It warns against using lead-acid chargers with desulfurization or pulse modes, so check your mower's charging setup before considering this battery.

The built-in display shows voltage. The maker describes the battery for lawn mower use, but doesn't specify Craftsman compatibility in the provided vehicle fit details.

8. CRAFTSMAN V20 20 in Lawn Mower: Best for a V20 mower battery platform

8

CRAFTSMAN V20 20 in Lawn Mower: Best for a V20 mower battery platform

8.4/10Our score

• Cordless 20 in push mower
• Two 5Ah V20 batteries included
• Two chargers included
• Up to 50 minutes runtime stated

This is a complete V20 push mower kit with two batteries and chargers, not a U1 starting battery. It belongs in a comparison for owners checking which Craftsman battery platform they have.

See it on Amazon

Pros

• Two batteries and chargers included
• V20 platform
• Brushless motor

Cons

• Not a replacement starting battery for a riding mower

This CRAFTSMAN kit is a cordless push mower, not a replacement starting battery for a riding mower. It includes two 5Ah V20 batteries and two chargers, and CRAFTSMAN states runtime of up to 50 minutes.

The V20 platform is for compatible CRAFTSMAN outdoor equipment and power tools. If you own this mower, shop for V20 packs and check tool compatibility rather than searching for a U1 lawn tractor battery.

Its 20 in deck and brushless motor distinguish it from the small 12V starter batteries elsewhere in this roundup. The kit also includes a grass bag, safety key and side-discharge chute.

9. CRAFTSMAN Push Mower: Best for a compact V20 push mower kit

CRAFTSMAN Push Mower: Best for a compact V20 push mower kit

8.2/10Our score

• 15 in cordless push mower
• Two 4Ah V20 batteries included
• Two chargers included
• Up to 45 minutes runtime stated

This 15 in push mower kit includes two V20 batteries and two chargers. Its removable tool batteries serve a different role from a riding mower's 12V starter battery.

See it on Amazon

Pros

• Two batteries and chargers included
• Compact 15 in mower
• Single-lever height adjustment

Cons

• Not a U1 replacement battery

This 15 in CRAFTSMAN push mower kit includes two 4Ah V20 batteries and two chargers. It is another complete cordless mower package, not a replacement battery for a Craftsman riding mower.

CRAFTSMAN states runtime of up to 45 minutes and describes the mower as 36% more compact and 29% lighter than traditional walk-behind mowers. Its single-lever height adjustment covers 1 to 3 inches.

Choose this type of kit when shopping for a cordless mower, not when replacing a riding mower's starter battery. The included V20 packs work on the V20 platform.

How do you choose a Craftsman mower battery?

Choose by the mower's specified battery group, voltage, CCA, dimensions and terminal layout. Check the manual or read the old battery label before comparing brands.

Check whether your Craftsman uses a U1 or V20 battery

A riding mower usually needs a dedicated starting battery, often in the U1 group. A cordless push mower uses removable tool batteries such as V20 packs, which are charged separately and power the mower motor.

For EGO equipment, check EGO lawn mower battery replacements against the specific tool.

Don't use the product name alone to identify the platform. If you need a walkthrough for removal and installation, see How to Change a Riding Mower Battery?.

Match dimensions and polarity

Measure the battery compartment and compare it with the replacement's length, width and total height. Also confirm positive and negative terminal placement; a battery can have the right voltage and still be unsuitable if the cables do not reach safely.

The U1 picks here have left-positive polarity, except where a product's details don't state polarity. The compact Mighty Max YTX4L-BS has the opposite layout, so confirm the exact arrangement before considering it.

Compare CCA only after confirming the group

Cold cranking amps describe starting current, but CCA doesn't tell you whether a battery physically fits or matches the mower's electrical system. Follow the manual's requirement, then compare candidates that meet it.

A 360 or 480 CCA battery isn't automatically a better choice for every mower than a 200 CCA battery. Compatibility, secure mounting and correct connections come first.

Treat lithium as a system compatibility choice

A lithium battery may differ from the lead-acid battery originally installed in the mower. Confirm the mower's charging system supports the battery chemistry and follow the battery maker's charger instructions.

The WEIZE U1 is described for Craftsman compatibility, while TYKOOL gives specific regulator and charger requirements for its smaller battery. Don't rely on voltage alone to decide whether either is suitable.

Where can you find Craftsman mower parts?

Craftsman parts availability depends on the exact model and part number. Use the mower's model number to search for the correct manual and replacement part, then verify the battery information against that manual.

Our guide to Who Sales Craftsman Lawn Mower Parts? covers places to look for model-specific parts. If you're diagnosing an engine issue at the same time, this guide on How To Replace Muffler On Craftsman Lawn Mower? covers a separate repair.

Verdict: which Craftsman lawn mower battery should you choose?

Choose the Mighty Max ML-U1 if your Craftsman calls for a 12V U1 battery near 200 CCA and its case and polarity match. Pick one of the MARXON or UPLUS U1 options only when its rating and dimensions meet your mower's requirements; consider lithium after verifying charging compatibility.

Frequently asked questions

What battery fits a Craftsman riding mower?

Many Craftsman riding mowers use a 12V U1 starting battery, but fit varies by model. Check the mower manual or the label on the old battery for group size, voltage, CCA, dimensions and terminal polarity.

Match those details before ordering, even when a replacement is described for Craftsman.

Can I use a higher CCA battery in my Craftsman mower?

A higher CCA rating can be suitable only if the replacement also matches the required voltage, battery group, dimensions and terminal layout. Follow your mower manual's requirements and don't assume that a bigger CCA number alone makes a battery compatible.

Secure fit and correct cable reach matter too.

Are Craftsman V20 mower batteries the same as riding mower batteries?

No. V20 batteries power compatible cordless tools and push mowers, while a riding mower's U1 battery is a 12V starting battery.

The CRAFTSMAN V20 mower kits here include removable tool batteries and chargers, not a replacement U1 starter battery.

Identify your mower type before shopping.

Can I replace a Craftsman lead-acid battery with lithium?

Only if the mower's charging system and battery requirements support the specific lithium battery. WEIZE describes its Group U1 LiFePO4 battery as compatible with Craftsman, while TYKOOL specifies a qualified regulator and dedicated LiFePO4 charger for its smaller battery.

Check the manual and charger instructions first.
