Can You Use a 12v Battery in 6v Power Wheels?

As a youngster, there was nothing more exhilarating than cruising around on our power wheels. But now that you’re all grown up, maybe you want to relive those glory days by dusting off your old power wheels and taking them for a spin. Just be sure to check the voltage first most power wheels use 6v batteries, but some models require 12v batteries. So before you go out and buy a new battery, make sure to double-check your power wheels’ specs.

Can you use a 12v battery in 6v power wheels? What about the other way around? In this article, we’ll explore the difference between 12v and 6v batteries, and whether or not you can use them interchangeably in your power wheels. Keep reading to learn more.

Battery Basics: 6v vs 12v:

Batteries come in all shapes and sizes, and each one has a different voltage rating. 6v batteries are typically used in power wheels, while 12v batteries are more commonly found in cars and other larger vehicles. So what’s the difference between these two types of batteries?

Well, for one, 12v batteries tend to have a higher capacity than 6v batteries. This means they can store more energy, which can be helpful for powering larger vehicles or devices. 12v batteries also tend to be more durable than 6v batteries, and they’re better able to withstand harsher conditions.

However, 12v batteries are also more expensive than 6v batteries. For this reason, some power wheels models use 6v batteries, which are cheaper and lighter than their 12v equivalents.

How To Connect A 12v Battery To A 6v Power Wheel:

Now that you know the difference between 12v and 6v batteries, let’s take a look at how you can connect them to your power wheels.

If you want to use a 12v battery in a 6v power wheel, you’ll need to purchase a 12v to 6v converter. This device will reduce the voltage of your 12v battery to 6v. Connect the converter’s two leads to your 12v battery, and then plug them into the corresponding ports on your power wheels vehicle.

However, keep in mind that even if you use a converter with a 12v battery, its capacity will still only be equivalent to that of a 6v battery. Most power wheel manufacturers recommend replacing a 6v battery with one of the same voltage. So if your power wheels vehicle originally used a 6v battery, make sure to use another 6v battery with your 12v converter.

If you’d rather run your power wheels on a 12v battery, you don’t need any equipment just plug and play.

Why Does it Matter What Type of Battery You Use in Your Power Wheels Vehicle?

Though you can technically use a 12v battery in your power wheels, the vehicle’s specs might not be designed for that type of voltage. A 6v battery is less powerful than a 12v one – but this also means it requires less amperage to charge and uses fewer materials to manufacture. A weaker battery has an impact on your vehicle’s performance, so it’s important to use a battery that is appropriate for your power wheels.

In the end, it’s up to you whether you want to use a 12v or 6v battery in your power wheels vehicle. Just be sure to read your vehicle’s specs carefully before making a purchase, and consult with an expert if you have any questions.

Can You Use a 12v Battery in 6v Power Wheels?

If your power wheel requires a 12v battery, you can’t simply swap it out for a 6v model. Doing so would weaken and possibly damage the motor, which is why we recommend using the correct voltage of the battery for your power wheels.

However, if your power wheels use a 6v battery, you can always upgrade to a 12v version. This isn’t recommended for children, as the additional voltage could be dangerous for inexperienced drivers. Plus, if your power wheels model doesn’t actually require a 12v battery (most of them don’t), then using one may disable it permanently.

Swapping out batteries can be a ton of fun, but make sure to double-check the voltage before you buy any batteries. This way you can ensure your power wheels are ready for some serious cruising.

Problems With Using A 12v Battery In 6v Power Wheels:

Using a 12v battery in a power wheel that only uses 6v batteries will cause damage to the electronics and your children may be at risk. Please take our word for it, if you are skeptical then please feel free to do some research before trying this. The main problem is that not all power wheels are made the same (the internal wiring), so if you try this with a power wheel that is not recommended to do so, you could be looking at some serious damage. If in doubt, please consult a professional or the manufacturer of your vehicle before making any changes.

What are the Alternatives for Power Wheels Batteries?

If you are looking for alternatives in power wheels batteries then the only way to go is with rechargeable power wheel batteries. You can purchase a rechargeable battery pack that will easily replace your current 6v or 12v battery, which will save you time and money in the long run. They are also much safer than regular power wheel batteries, no more worrying about your child swallowing batteries. Please see DIYElectricCar’s tutorial on how to build a rechargeable power wheels battery pack here.

If you are looking for replacements then it is recommended to either use the same voltage or purchase one of the same volts as what you already have. Using anything else could damage your vehicle permanently so please do not try this without consulting a professional first.

Conclusion paragraph: In short, the answer is yes. A 12v battery can be used in a 6-volt power wheels vehicle with no problems. There are some safety precautions to take into consideration before proceeding though- for instance, you need to ensure that your charger is set at 6 volts and not have it on its highest setting which would cause overheating of the battery.
