Method 1: Charging Power Wheels Battery With Power Supply

Here’s what you’ll need:

  • Power supply
  • Lead-based battery
  • Two alligator clips
  • Battery holder
  • Wire cutting tools

Step 1. Cut and remove output wires

Begin by cutting and removing output wires. Connect the green wire with the black wire to switch.

Step 2. Hook the battery to the power supply

Using two alligator clips, connect the battery holder to the supply. It will help adjust the positive and negative terminals. Make sure that the leads, battery holder, and cell link are solid and secure.

Step 3. Adjust the voltage and current

Set the charge voltage and the current limit. You should know that a 13.8V, 2A is needed to charge a 12V power wheels battery while a 6V, 2A power output is required for a 6V battery.

Step 4. Check the battery

While charging, don’t forget to monitor the temperature, current, and voltage. The room temperature should be moderate and the place well-ventilated. Check if the charge is complete, then disconnect the power supply, and test the battery on the power wheels.

Method 2: Charging Power Wheels Battery With Solar Panels

Here’s what you’ll need:

  • Battery
  • Screwdriver
  • Charge controller
  • MC4 connectors

Step 1. Set up charge controller

Install the charge controller on a non-conductive material like PVC panel or wood. Next, run the panel to the controller and fix the positive and negative terminal to the battery.

Step 2. Slip the terminals

Insert the terminals inside the outlet of the charge controller. Then, fasten the screws and position the cables.

Step 3. Join the cables

Connect the outer wires with the MC4 connectors and the charge connectors with the terminals. Slip them into the outlet and fasten them with screws.

Step 4. Connect the wires

Attach the control wires to the solar panel and set up the positive and negative connectors. Split the MC4 connections into place. Test the output on the connectors to check if it is working.

The charging time varies depending on the battery size, wattage of the solar panel, and weather. When the output is dropping, the battery is close to being fully charged.

Connect the step-down converter module to the adapter wires. Make sure to tighten the screw terminals. Afterwards, hook the alligator clip.

Step 3. Plug in the adapter

Plug the adapter, then connect the two alligator clips over the multimeter.

Step 4. Check the voltage and current

Set the necessary series of voltage and current you see on the multimeter.


  • Short-circuiting the battery’s supply terminal can cause an explosion, and it doesn’t work anyway.
  • Always check safety precautions in the instruction manual of the power wheels before trying any of the above methods.
  • Don’t leave the battery charging overnight, as it can lead to overcharging and cause damage.
  • Using a high current to reduce the charging time is not good for the battery. Instead, opt for a source and voltage that is suitable for the power wheels to keep the battery in mint condition.

Frequently Asked Questions About Power Wheel Battery and Charger


Did that method not work for you? There could be other issues that you are not aware of. Check this FAQ section, and you might find the solution to the problem you are having with the power wheel battery or charger.

1. Why won’t the battery charge?

Are the connectors adequately attached? Try unplugging the battery and inspecting it. If it still doesn’t work and the battery is covered by a warranty, reach out to the retail outlet or manufacturer for assistance.

Another reason could be the condition of the batteries. When a battery has been put for over two years of use, it is highly likely to reach its expiry date. A replacement battery is needed in this case.

2. How to tell if the battery is charging?

The first charge of a battery should be at least eight hours. Then, locate the positive and negative prongs of the battery to monitor the voltage reading. Use a digital voltmeter and turn the dial to the voltage DC portion. You will see a symbol that indicates the battery is charging. That way, you will get an accurate reading for any 12V application.

3. Is it safe to charge power wheels without the charger that came with it?

Using alternative methods in charging a power wheel battery is safe when you do it a few times. Always remember to keep a close eye on the battery when you are charging it using other methods. Disconnect the battery when it’s full and never overcharge it.

These emergency methods can be a good substitute that you can rely on without a charger. However, it is still better to purchase a replacement charger as soon as possible to preserve the battery life.

6. How to tell if the battery charger is not working?

There is a specific charging time that indicates when the battery is full and ready to use. A faulty charger doesn’t deliver a full charge within the given time. If the charge runs out faster than the said running time, it is another sign that the charger or the battery might be defective. When the battery doesn’t charge, it is a dead giveaway that you need a new battery charger.

Replacement should be done as soon as possible. If you keep using a defective charger, it can damage the power wheel’s battery.
