Power Wheels repair
I have a 12V Power Wheel that won't go, press the pedal and nothing. The battery shows ~12V, and I removed the motors and I'm getting 12V at the terminals when I press the pedal. Motor shows about 1.5ohm (I read that > 0.5 is "bad" but not sure if that's right). I connected a motor direct to the battery and it turned slowly a few times then stopped. I connected the motor direct to the wall charger and it pulses but never spins (I guess the charger pulses?). The motor "feels" right when I spin it manually, and I can make it show a voltage when I spin it.

Is the battery shot? Can it show good voltage but just not put out any current? It's not damaged or bulging, and it ran well on one charge and then nothing on the next.

re: Power Wheels repair
Well I think I just answered my own question. I had the battery on the charger for a while, and I took it off and it showed 13.5V. I put a motor on it, it spun a few times then stopped, and the battery now shows 11.5V. It's shot.

I guess I just don't know enough about how batteries work.

I have one of those chinese power wheels with the remote. I think about about to find some more powerful motors for it.

Batteries Plus Bulbs works on them. I took my sons in a few years ago and the pricing was fair.

You can get replacement parts on Amazon. Repaired an old one that my oldest son used for a while. Think it got left out in the rain. Popped in a new battery and bought a fresh charger and the youngest boy loves it.

re: Power Wheels repair
Yeah I bought a 3rd party battery for $45 (official brand were $75). Pretty sure that'll solve my problem.

re: Power Wheels repair
I just tweaked my daughters ATV ride on that we had bought from Big Toys Green Country.

The atv came with two 12v 7AH batteries in parallel. They weren't providing nearly enough power for the 4 electric motors and it would die within 10 minutes or so. I ordered some additional batteries on amazon. More than what I needed came, and I couldn't return them so I added them all into the car.

So now in parallel, I've got the original 2V 7AH batteries. Then I added two 12v 12AH batteries under the seats and an additional 12V 35AH battery under the hood. I also added a charging cable for my battery charger, which seems to work much better than the AC pack that was included. Now it seems to run forever and the kids are loving it.

One thing I learned about these ride on cars are that most of them have thermal fuses before the batteries to make sure that the motors dont overheat. If it gets near that point, the car shuts off for 15-20 seconds and you have to restart it. The kids driving through high grass or over tree roots would cause this to happen. I couldn't figure out for the life of me why the car kept stalling like that. Now we just run it on freshly cut grass or on the asphalt.

There are YouTube videos that show you how to move up to 24v or even 48v I think. I wasn't looking to bypass the existing car computer for increased speed (as it has the remote control feature and bluetooth connection for music). Plus the car at top speed goes 6 or 7 MPH, which is more than fast enough for my 4 year old.

I thought about Tool-Timing it, but decided against it because it's fast enough.

Though I did just watch a video for 24v conversion for the dune racer, and the kid is fricking drifting all around.

re: Power Wheels repair
You can pick up new batteries for them from Lowe’s or Home Depot for a lot less than the OEM battery and they are all made by the same people at the end of the day.
