Best Power Wheels Replacement Batteries (2026): 6V, 12V and 24V Ride-On Batteries
Affiliate disclosure: RiderMojo may earn a commission from qualifying purchases, including as an Amazon Associate, at no extra cost to you.
When a Power Wheels or other kids’ ride-on starts crawling, dies after ten minutes or won’t take a charge, the battery is usually to blame. Ride-on batteries are mostly sealed lead-acid, and they wear out, especially after a winter of sitting uncharged. The good news is that a replacement is one of the cheapest fixes in the toy box, as long as you get the right voltage, connector and size.
This guide covers eight replacement batteries for 6V, 12V and 24V ride-ons, including official Fisher-Price Power Wheels and Peg Perego batteries, longer-running upgrades, and universal options for the Amazon-brand ride-ons that use a red 2-pin plug. Every listing was live and available on Amazon when we checked on November 3, 2026.
How we picked: We did not hands-on test these specific batteries for this article. We compared each Amazon listing’s voltage, capacity, connector, compatible part numbers, dimensions and warranty, confirmed each listing was live and available, and favored batteries that clearly state which vehicles they fit. Run-time claims are the manufacturers’ and will vary with the vehicle, the rider and the terrain.
From the RiderMojo garage: Batteries are the heart of everything we cover, from our son’s first Razor E100 to the 72V Eahora M1PS and the EVs our founder drove for years of rideshare work. Kids’ ride-ons follow the same rules as bigger EVs: match the voltage, treat the battery well, and it lasts longer.

Short answer: If you own a Fisher-Price Power Wheels with the all-gray 12V battery, the official Power Wheels 12V or the Impact Battery 12Ah is the safe, drop-in choice. If you want more ride time, the Impact 15Ah upgrade also covers the gray-with-orange-top system. For most Amazon-brand ride-ons with a red 2-pin plug, look at the SafeAMP 9.5Ah after measuring your old battery.
First: Identify the Battery You Have
Before you order, pull the old battery and check four things:
- Voltage: printed on the battery and usually on the vehicle (6V, 12V or 24V). Never install a higher voltage than the vehicle is built for.
- Color and part number (Power Wheels): High-Tech Battery Solutions, a battery retailer, notes that gray Power Wheels batteries are 12V while red and blue ones are 6V. The 12V gray batteries come in two styles, all-gray and gray with an orange top, and not every replacement fits both.
- Connector: Fisher-Price and Peg Perego use their own plugs. Many Amazon-brand ride-ons use a small red 2-pin connector, and some 24V UTVs use an Anderson-style plug.
- Size: Measure length, width and height. A higher-capacity battery is often physically bigger and may not fit the compartment.
Watch: High-Tech Battery Solutions walks through how to tell whether the problem is the battery, the charger or the vehicle, so you don’t buy a battery you don’t need.
1. Power Wheels 12-Volt Rechargeable Battery (Official, Gray) — Best OEM 12V
This is the official Fisher-Price Power Wheels 12V gray battery. The listing says it fits any Power Wheels vehicle that requires a 12V, 12Ah battery. It’s a sealed lead-acid design and works with the charger that came with your vehicle. A charger is not included.
Fisher-Price’s instructions are specific: charge at least 18 hours (but no more than 30) before first use, recharge for at least 14 hours after each use, and fully charge the battery before storage and at least once a month. Following those rules is the best way to avoid early battery failure.
Key specs

2. Impact Battery 12V 12Ah All-Gray Replacement — Best Gray 12V Alternative
Impact Battery describes itself as an authorized Power Wheels service center, and this 12V 12Ah battery is built to replace the all-gray Power Wheels battery (part numbers 00801-0638, 00801-1869 and 1001175653). It is not a replacement for the gray battery with the orange top.
The battery has an internal self-resetting fuse and a non-spillable sealed design. Impact says the 12Ah battery outperforms the older 9.5Ah version by about 25%, and it backs the battery with a 6-month manufacturer warranty.
Key specs
- 12V, 12Ah sealed lead-acid (AGM)
- Replaces 00801-0638, 00801-1869, 1001175653 (all-gray only)
- Internal self-resetting fuse
- Weight: about 10 lb
- Warranty: 6 months
Pros
- Clear part-number compatibility
- Sold by an authorized Power Wheels service center
- 6-month warranty
Cons
- Doesn’t fit gray/orange-top systems
- Same weight and charge times as OEM lead-acid
Best for: Power Wheels owners with an all-gray 12V battery who want a warrantied replacement.
3. Impact Battery 12V 15Ah Upgrade — Longest-Running 12V
If your kids always run the battery flat, this 15Ah upgrade is the most capacity you can drop into a 12V Power Wheels without rewiring. Impact says it lasts over 50% longer than the original 9.5Ah battery and up to 25% longer than the 12Ah version.
It’s also one of the few replacements listed for both 12V Power Wheels styles, all-gray and gray with orange top, covering part numbers 1001175653, 1101506087, 00801-0638, 00801-1869, 00801-1661 and 00801-1776. Like the 12Ah version, it has an internal self-resetting fuse and is non-spillable, and Impact backs it with a full 1-year warranty.
Key specs
- 12V, 15Ah sealed lead-acid
- Fits all-gray and gray/orange-top 12V Power Wheels systems
- Internal self-resetting fuse; non-spillable
- Dimensions: 5.25 x 4.25 x 5.51 inches; about 10.2 lb
- Warranty: 1 year
Pros
- Most run time of the 12V picks
- Covers both 12V Power Wheels battery styles
- Longest warranty among the 12V lead-acid picks
Cons
- Bigger battery takes longer to recharge

Best for: Families whose kids want longer rides from a 12V Power Wheels.
4. Peg Perego Official 12-Volt Battery — Best for Peg Perego Ride-Ons
Peg Perego ride-ons, including the licensed John Deere tractors and Gators, Polaris and Case IH models, use their own battery and plug. This is Peg Perego’s official 12V replacement (model IAKB0501), and the company warns that non-official batteries could damage the vehicle and may cause issues not covered by the warranty.
Peg Perego calls it an all-season, heavy-duty battery and notes that it needs no separate fuse. Many families buy a second one so kids can swap in a charged battery and keep riding.
Key specs
- 12V, 12Ah lead-acid
- Official Peg Perego part (IAKB0501)
- Fits John Deere, Polaris, Case IH and New Holland Peg Perego ride-ons
- No fuse needed
- Warranty: 6 months
Pros
- Factory fit and plug for Peg Perego vehicles
- Protects your vehicle warranty
- Good as a swap-in spare
Cons
- Stock was low when we checked
- Only for Peg Perego vehicles
Best for: Owners of Peg Perego John Deere, Polaris or Case IH ride-ons.
5. Mighty Max 12V 7Ah Drop-In Kit with Harness — Budget Fix for Gray Power Wheels
Mighty Max’s kit pairs a standard ML7-12F2 12V 7Ah sealed lead-acid battery with a complete wire harness that plugs into a 12V Power Wheels. It also includes four 40-amp fuses. Mighty Max says it’s compatible with all gray 12V Power Wheels batteries, but not orange-top batteries.
The upside is that the battery itself is a common size, so future replacements are easy to find and you can keep the harness. The trade-off is capacity: 7Ah is a little over half the 12Ah of the official battery, so expect shorter rides.
Key specs
- 12V 7Ah SLA battery (ML7-12F2) plus wire harness
- Includes four 40A fuses
- Compatible with gray 12V Power Wheels (not orange-top)
- Battery weight: about 5 lb
- Warranty: 1 year
Pros
- Lighter than 12Ah batteries
- Standard battery size is cheap to replace later
- 1-year warranty and spare fuses
Cons
- Noticeably less run time than 12–15Ah options
- Doesn’t fit orange-top systems
Best for: Budget-minded parents who want a quick fix for a gray 12V Power Wheels.
6. SafeAMP 12V 9.5Ah Battery with Red 2-Pin Connector — Best for Amazon-Brand Ride-Ons
Many of the ride-on cars sold on Amazon, like the remote-control models in our guide to Power Wheels with remote control, use a small 12V battery with a red 2-pin connector. SafeAMP’s 9.5Ah battery comes with that harness and a replaceable 40-amp fuse, and it offers more capacity than the 7Ah batteries many of those cars ship with.
SafeAMP is upfront that fit matters. The battery measures 5.9 x 2.5 x 3.9 inches, and it works only with the red 2-pin connector shown in its photos. Compare your plug and measure your battery compartment before ordering.
Key specs
- 12V, 9.5Ah sealed lead-acid
- Red 2-pin connector harness with replaceable 40A fuse
- Dimensions: 5.9 x 2.5 x 3.9 inches
- Warranty: 6 months
Pros
- More capacity than common 7Ah batteries
- Plug-and-play harness and fuse included
- Clear fit warnings
Cons
- Only for the red 2-pin connector
- Won’t fit every battery compartment
Best for: Owners of Amazon-brand 12V ride-ons with a red 2-pin battery plug.
7. Power Wheels 6-Volt Rechargeable Battery (Official) — Best for 6V Toddler Models
Smaller toddler Power Wheels run on 6V. This official Fisher-Price battery is for Power Wheels vehicles that require a 6V, 9.5Ah lead-acid battery. As with the 12V, there’s no charger in the box, so use the one that came with the vehicle.
The charging rules match the 12V battery: at least 18 hours (no more than 30) before first use, at least 14 hours after each use, and a full charge before storage. Check your old battery’s color and connector first, since Power Wheels has used more than one 6V battery style over the years.
Key specs
- 6V, 9.5Ah lead-acid
- Official Fisher-Price Power Wheels part (model 74522)
- Dimensions: 5.87 x 5.91 x 7 inches; about 5.1 lb
- Charger not included
Pros
- Factory part for 6V Power Wheels
- Simple drop-in replacement
Cons
- Not universal across every 6V battery style
- Long charge times
Best for: Parents of toddlers with a 6V Power Wheels.
8. Tnvodejo 24V 8Ah Lithium Battery — Best 24V Upgrade
Most 24V ride-on UTVs, such as the Dynacraft Realtree UTV, ship with a heavy lead-acid battery. Tnvodejo’s 24V 8Ah lithium pack is listed as a direct replacement for 12FM7 lead-acid batteries and weighs only 4.63 lb. It comes with an Anderson plug, and Tnvodejo claims 2–3 hours of play per charge.
A built-in 30A battery management system (BMS) protects against overcharging, over-discharging, overcurrent, short circuits and overheating. The battery is designed for 24V motors from 0 to 600W, shouldn’t be wired in series or parallel, and has a 1-year warranty. Check your battery’s dimensions and connector before buying.
Key specs
- 24V, 8Ah lithium-ion with 30A BMS
- Replaces 12FM7 24V lead-acid batteries
- Dimensions: 3.9 x 4.2 x 9.4 inches; 4.63 lb
- Anderson plug; charge-status light
- For 24V motors up to 600W
- Warranty: 1 year
Pros
- Far lighter than lead-acid
- Built-in BMS protection
- Low self-discharge for winter storage
Cons
- Fit and connector vary across 24V ride-ons
- Confirm you have a lithium-compatible charger before switching
Best for: Owners of 24V UTVs and ride-ons who want a lighter, longer-running battery.
Prefer to stay with lead-acid? Tnvodejo also sells a 24V 7Ah sealed lead-acid replacement (12FM7 type, about 11 lb, 7.8 x 4.1 x 5 inches) for 24V ride-ons. Check price on Amazon
Buyer’s Guide: How to Choose a Ride-On Replacement Battery
1. Never change the voltage
A 6V car needs a 6V battery, a 12V car needs a 12V battery, and so on. Putting a higher-voltage battery in a ride-on can overheat motors and wiring. Upgrading to a higher-voltage system is a modification, not a battery swap.
2. More amp-hours means longer rides
Capacity (Ah) is the “gas tank.” Going from 7Ah to 9.5Ah, 12Ah or 15Ah at the same voltage generally adds run time, as long as the bigger battery fits and uses the right connector.
3. Match the connector and the compartment
Fisher-Price, Peg Perego and many Amazon brands all use different plugs. Avoid cutting and splicing wires unless you know what you’re doing. A battery with the correct harness, like the Mighty Max kit or the SafeAMP, is safer and easier.
4. Lead-acid or lithium?
Sealed lead-acid batteries are cheaper and match the original equipment in most ride-ons. Lithium packs are much lighter, hold their charge better in storage and often run longer, but they need a compatible charger and a battery management system. Don’t charge a lithium battery with an old lead-acid charger unless the battery maker says it’s OK.
5. Don’t forget the charger
If the battery won’t charge, the charger may be the real problem. A replacement 12V charger for Power Wheels gray and orange-top batteries, like this 12V 1A charger with a red/green status light, is much cheaper than a new battery. Confirm the connector matches first.
6. A word on drill-battery conversions
You’ll find lots of videos about running Power Wheels on 18V or 20V power-tool batteries. These conversions add speed and power, but they change the vehicle’s design, can damage motors and switches, and usually void the warranty. For a child’s toy, we recommend sticking with a battery made for the vehicle.
Watch: High-Tech Battery Solutions’ parent’s guide covers finding the right Power Wheels battery, charging it correctly and knowing when it’s time to replace it.
Power Wheels Battery FAQ
How long does a Power Wheels battery last?
It depends on use, storage and charging habits. Lead-acid ride-on batteries wear out faster if they sit discharged. Fisher-Price says to fully charge the battery before storage and at least once a month to prevent early failure.
How long should I charge a Power Wheels battery?
For official Fisher-Price batteries, charge at least 18 hours (no more than 30) before first use, then at least 14 hours (no more than 30) after each use. Other brands have their own instructions, so follow the manual that came with your battery.
Can I put a bigger battery in my Power Wheels?
You can usually use a higher-capacity battery at the same voltage, such as the Impact 15Ah in place of a 12Ah, if it fits and has the right connector. Don’t install a higher-voltage battery.
What’s the difference between the gray and the gray/orange-top Power Wheels battery?
They are two different 12V battery systems. Some replacements, like the Impact 12Ah and the Mighty Max kit, fit only the all-gray style. The Impact 15Ah lists compatibility with both.
Can I use a car battery in a Power Wheels?
No. Car batteries are far heavier, are made for engine starting rather than toy use, and don’t fit or connect safely. Use a sealed battery made for ride-on toys.
How do I dispose of an old ride-on battery?
Don’t throw lead-acid batteries in the trash. Many battery and auto-parts retailers take them back, and Call2Recycle accepts small sealed lead-acid and lithium-ion batteries at participating drop-off sites.
Final Thoughts
The right replacement battery brings a “dead” ride-on back to life for a fraction of the cost of a new one. For Fisher-Price Power Wheels, choose the official 12V or the Impact 12Ah for a straight swap, or the Impact 15Ah for longer rides. Peg Perego owners should stick with the official Peg Perego 12V. The Mighty Max kit is a budget fix, the SafeAMP suits Amazon-brand cars with a red 2-pin plug, the official 6V covers toddler models, and the Tnvodejo 24V lithium is a lighter upgrade for 24V UTVs.
Check your old battery’s voltage, connector, part number and size, then check current pricing on Amazon.
