Best Power Wheels Lithium Battery

Lithium batteries are you best option for replacing or upgrading the battery of your Power Wheels. They are rechargeable, last longer, and will naturally be installed in your Power Wheels.

The following article simplifies the lithium battery options available on the current market and presents you with our picks for the best products.

How Do Lithium Batteries Work?

Lithium batteries are highly popular for electronics. They work more efficiently than typical acid-based batteries because all the battery needs to function is lithium ions. These ions bounce around within the battery creating electricity.

These lithium ions can be recharged meaning you can get a much longer lifespan for your battery. They can also store and redistribute a larger quantity of energy, meaning they can be used for longer between charges.

Both of these key factors ensure your Power Wheels has maximum power and can be enjoyed for much longer.

Types of Lithium Batteries

The main feature that varies between the types of lithium batteries is the number of volts (or voltage). Voltage is important as it translates to the amount of power (and speed) that your Power Wheels have.

Many people modify their Power Wheels to include a battery with higher voltage to help their children get better Power Wheels performance over more difficult terrains. It is important to note that the voltage of your battery will not impact the amount or length of charge in your battery. 

There are three common types of lithium batteries:

12 Volts

This is the battery that will come standard in most Power Wheels (see also ‘The Top 5 Fastest Power Wheels To Buy‘). Generally, it will give you 1-2 hours of runtime for 8-12 hours of charge. This will be the most economical option to purchase

18 Volts

These are often used in battery-operated power tools so you may find you already have them floating around the shed. These are a great option for those who are looking to make extra use out of the batteries as you can use them without the Power Wheels.

When considering upgrading to an 18V battery it can help to buy name-brand products as these will have the biggest range of battery-operated tools for you to take full advantage of your purchase.

24 Volts

This is the largest lithium battery you will be able to fit your Power Wheels. It will provide you with twice the amount of power and speed that the original battery would.

You should consider the age and maturity of your children before installing this battery as it will allow them to drive quite quickly and may not be appropriate for some younger children.

If you are looking for a longer charge on your battery look into options with higher ‘amps’. It is also worth investing good money for a high-quality battery as this will limit the number of replacements that you will need to do in the future.

How to Choose the Right Battery for You.

Choosing the right lithium for you depends on what you want to get out of the product. There are all kinds of lithium batteries to suit a variety of budgets and needs so having an idea of what you are looking for can be very helpful. 

Price: generally speaking, the lower the voltage the lower the price of the product. If you are looking to save the most money invested in a high-quality, low-voltage battery. 

12V batteries should cost around $80-$100.

18 V batteries should cost around $90-$300. 

24 V batteries should cost around $200-$1000.

Power and speed: if you are looking to get better performance in terms of power and speed consider upgrading to an 18V or 24V battery. 18V would be the best option in terms of value for money and ensuring your child does not have too much power to handle.

Charge: if you are looking for longer use between charges look into batteries with more amps (AH).

Tips to Care For Your Power Wheels Lithium Battery.

Keep It Dry

The battery is not waterproof and its casing is not water-resistant. It is good practice to keep your Power Wheels out of the rain, snow, or puddles in general as has many unprotected electrical components. Alternatively, you can work towards modifying your Power Wheels to be waterproof. 

Don’t Leave Your Charger on for Extended Periods of Time

This will overload and potentially damage your battery. Lithium batteries will generally take between 8-12 hours to charge (check manufacturer recommendations for more specific indications). It is best to take the batteries off charge as soon as you believe that the battery is fully charged. This will help increase the life span of your battery over time.

Don’t Let the Battery Get Too Cold

When batteries are exposed to extreme or prolonged cold, they tend to lose their charge quickly. The cold can permanently damage your battery leading to less enjoyment and more frequent replacements.

To avoid damage from the cold, try to store your Power Wheels battery somewhere dry and warm (preferably indoors). You can also invest money in insulation for your battery including thermal cases and auto blankets. Insulating your battery would be an excellent idea if you are playing to modify your Power Wheels to be used over the winter.

Do Run the Battery Until Absolutely Flat

If you can avoid running the battery until completely flat you will see a dramatic improvement in the longevity of your battery. Running the Power Wheels until the battery is completely flat can dramatically decrease its ability to store charge over time.

Try to Charge the Battery in Increments

Charging the battery by say 20-30% at a time can dramatically improve the longevity of the product and your battery life each use.

Use a Charger That Comes From the Manufacturer as the Battery

The manufacturer of the battery is the best person to purchase your charger from. While you can use any chargers it is not advisable and will not be as effective in the long run. 

Be Mindful of How You Store Your Batteries Over Long Periods of Time

  • If you are planning to store your lithium battery for an extended period of time, do not store it fully charged. It is best practice to try and store it around 40-50% charged.
  • Store it in a dry, warm place. Water and low temperatures can damage your battery.
  • Charge and use it every month or so. This will stop your battery from becoming stagnant and losing charge.


Investing money in a good and reputable lithium battery is definitely the way to go to get the most out of your Power Wheels. Before you begin the buying process it can really help to look into all of the available options and weigh up what is most important as the market is saturated in products that will be right for you no matter what you choose to prioritize.
