How to Test Power Wheels Batteries

Power Wheels batteries are the life force behind these popular ride-on toys for kids. They provide the energy needed for the vehicle to move and perform. 

But, like all batteries, they have a limited lifespan, and it’s important to test them regularly to ensure they’re still working properly. 

In this guide, we’ll show you how to test Power Wheels batteries and give you some tips to extend their lifespan.

Materials Needed:

  • A multimeter
  • Power Wheels vehicle
  • Charger (if necessary)

Step 1: Prepare the Power Wheels Vehicle

Before testing the batteries, it’s important to make sure the vehicle is safe. Remove the key, disconnect the battery, and place the vehicle on a flat surface. This will help ensure that the vehicle doesn’t accidentally start while you’re testing the batteries.

Step 2: Check the Voltage of the Batteries

The first step in testing the batteries is to check the voltage. To do this, you’ll need a multimeter. Connect the multimeter to the batteries and turn it on. A healthy voltage reading should be between 12.4 and 12.7 volts for a 12-volt battery. If the reading is lower than 12.4 volts, it’s time to replace the batteries.

Step 3: Check the Current Draw of the Vehicle

Next, you’ll need to check the current draw of the vehicle. This will help you determine if there’s an issue with the wiring or a component that’s draining the batteries. 

Connect the multimeter to the positive and negative terminals of the batteries, and set it to the “Amps” setting. Then, turn on the vehicle and observe the reading. 

A healthy current draw should be between 0 and 2 amps. If the reading is higher, it could indicate a problem with the vehicle that needs to be addressed.

Step 4: Charge the Batteries if Necessary

If the voltage of the batteries is low, it’s time to charge them. Make sure to use a charger specifically designed for Power Wheels batteries. Follow the manufacturer’s instructions for charging the batteries, and don’t overcharge them.

Types of Chargers for Power Wheels Batteries

  • Wall-Plug Charger: The simplest and most common type of charger for Power Wheels batteries, the wall-plug charger is easy to use and convenient. Simply plug the charger into an electrical outlet, and connect it to the batteries. Wall-plug chargers are typically the most affordable option, but they may not be as fast or efficient as other types of chargers.
  • Smart Charger: A more advanced type of charger, the smart charger is designed to automatically adjust the charging rate based on the needs of the batteries. This helps to extend the lifespan of the batteries, as it prevents overcharging and undercharging. Smart chargers are more expensive than wall-plug chargers, but they offer more convenience and peace of mind.

Testing a Battery

There are several factors to consider when testing a Power Wheels battery, including the type of battery, the brand, and the application.

Batteries By Type

Lead-Acid Batteries: The most common type of battery used in Power Wheels vehicles, lead-acid batteries are relatively affordable and widely available. They offer good performance and reliability, but they have a limited lifespan and can be heavy.

Lithium-Ion Batteries: A newer type of battery, lithium-ion batteries are lighter and more efficient than lead-acid batteries. They also have a longer lifespan and are less likely to leak. However, they can be more expensive than lead-acid batteries, and they may require a different type of charger.

Batteries By Brand

Different brands of Power Wheels batteries offer varying levels of performance, reliability, and value. Some popular brands include Duracell, Energizer, and Power Wheels.

Batteries By Application

The type of Power Wheels vehicle you have will also affect the type of battery you need. For example, a small ride-on car may only require a 6-volt battery, while a larger, more advanced vehicle may require a 12-volt battery

It’s important to check the specifications of your Power Wheels vehicle before selecting a battery, as using an incorrect battery can cause damage to the vehicle or the battery itself.

Tips & Tricks:

  • Store the Power Wheels vehicle in a cool, dry place when not in use.
  • Avoid overcharging the batteries, as this can damage them.
  • Don’t discharge the batteries too much, as this can also damage them.
  • Clean the battery terminals and connections regularly to ensure a good electrical connection.

How often should I test my Power Wheels batteries?

It’s recommended to test your Power Wheels batteries every 3 to 6 months, or whenever you notice a decrease in performance.

Can I use a regular car battery charger to charge my Power Wheels batteries?

No, it’s important to use a charger specifically designed for Power Wheels batteries. Using a regular car battery charger can damage the batteries and void the warranty.

What’s the difference between a 12-volt and 6-volt Power Wheels battery?

The main difference is the amount of voltage that each battery provides. A 12-volt battery provides more power, while a 6-volt battery provides less. The appropriate battery for your Power Wheels vehicle will depend on the model and specifications.


Testing your Power Wheels batteries is an important part of maintaining your child’s ride-on toy. By following the steps outlined in this guide, you can ensure that your batteries are working properly and extend their lifespan. Remember to always handle the batteries and vehicle safety, and if you’re unsure about any aspect of testing, consult the manufacturer.
