Do you also need a charger?

Honest answer: only if your current one is failing. Here's how to tell.

• Just the battery (this listing) if your charger still works and the cord is in good shape. No reason to pay for one you don't need.
• Battery + charger together if your charger is several years old, has a frayed cord, won't light up, or went missing. A tired charger is the most common reason a "dead" battery never seems to come back — grab the battery and charger kit instead.
• Not sure? Send us the model number or call 1-877-775-4381. We'll tell you straight, even when the cheaper option is the right one for you.

About the Power Wheels 12V battery

This is the grey 12-volt battery that powers the bigger Power Wheels rides: the Jeep Wrangler, Mustang, Cadillac Escalade, Ford F-150, Harley-Davidson, Kawasaki Brute Force, and dozens more full-size models. If your child's ride-on uses the grey battery, this is the one you want.

On a full charge, you can expect about 45 minutes to an hour of playtime. How long you actually get comes down to the little things: how heavy the rider is, whether they're on grass or smooth pavement, and which speed setting they're using. A lighter child cruising the driveway will get the most time; a bigger kid racing across the lawn at top speed will get a little less. That's completely normal, and it doesn't mean anything is wrong with the battery.

The battery is sealed and maintenance-free, with no fluid to check, and has an internal fuse for protection during normal use. The toy is engineered to give you three to four years; most parents only get one to two, and the gap is almost always charging and storage habits rather than the battery itself.

How to install it

Four steps, no tools beyond what came with the toy.

1. Open the battery compartment on your Power Wheels. On most models it's under the hood or seat. If you're unsure, check your toy's manual.
2. Disconnect the old battery by pulling apart the connector. Do not pull on the wires.
3. Lift the old battery out. Keep it for recycling. Most auto parts stores take SLA batteries at no charge.
4. Place the new battery in the same orientation and reconnect the connector. It only fits one way, so don't force it. Give it a full charge before the first long ride.

How to make it last

Charge it after a good play session, don't leave it sitting dead for weeks, and bring it indoors over winter. Those three habits are what separate a battery that lasts one season from one that lasts several.
