Why My Power Wheels Run Shortly ? ( and what to do )

It happens all too often. A short run time for power wheels means that the battery is undercharged, too old to hold full charge, or that the thermal fuse has tripped. Loose wire can be also the reason of this problem.

In this guide we’ll delve into these causes, show you how to diagnose them, and provide solutions for each scenario.

Why Does the Battery Die So Quickly?

Possible Cause 1 : You didn’t charged the battery fully

First things first, if it is the first use, ask yourself if you charged the battery like recommanded by the constructor ? A new battery should be charged for at least 18 hours before the first ride. After that, make it a habit to recharge the battery for at least 14 hours after each use. But remember, never let it charge for more than 30 hours.

So if you match with this scenario, charge the battery fully ( between 18 and 30 hours ) and the problem is solved.

Possible Cause 2: Loose Wires or Connectors

Secondly, Sometimes, the culprit is as simple as a loose wire or connector. Such minor issues can interrupt the charging process and lead to a short time run. So, you need to make sure the battery connector is snugly plugged into the charger, and that the charger is plugged into a working wall outlet ( yes, the issue does not necessirely come from the power wheels itself).

Try to do that before the next run, if the power wheels time run was ok, then that was the problem for the previous charging cycle.

Possible Cause 3: The Battery is damaged

If you’ve been charging the battery for more than 30 hours regularly, chances are you’ve damaged it, because this can reduce its ability to hold charge. Overcharging can be a silent battery killer.

On the other hand, even the most well-cared-for batteries have a shelf life. Typically, a Power Wheels battery will last between 1 to 3 years. If you notice that the battery isn’t holding a charge as it used to, it’s likely nearing the end of its lifespan.

To check the health of the battery by yourself, you can use a multimeter to measure its voltage. A fully charged 12V Power Wheels battery should read around 12.6 to 13 volts. If it’s significantly lower even after a full charge, it means that the battery is damaged and may need replacement.

Possible Cause 4: The Thermal Fuse is Tripped

Sometimes, the built-in thermal fuse may “trip” and shut down the vehicle. This can sound a bit intimidating, but it’s actually a safety feature. It happens if the vehicle is overloaded or if the driving conditions are too severe.

If this happens, tell your child to take their foot off the pedal and wait for about 25 seconds before resuming play. To avoid this issue in the future, make sure not to exceed the maximum weight capacity of the power wheels or tow anything behind the vehicle.

Well, in some case, the thermal fuse keeps tripping without reason. here, it’s time to contact the service center of the vehicle.
