Power Wheels 12V Battery Alternative- What Is Your Best Choice?

Power Wheels toy vehicles use a 12-volt battery to turn the electric motor. At some point in time, you will need to replace the battery.

At this point, you might be considering using an alternative Power Wheels battery. Still, you must be careful to choose the correct type. 

Don’t be tempted to use a standard 12-volt car battery, as this will not last. You must choose a 12-volt deep-cycle lead-acid battery.

What To Consider When Installing An Alternative 12-volt Power Wheel Battery?

Battery Type

When choosing an alternative, you need to decide between a standard lead-acid or the newer lithium-ion phosphate version.

Lead-acid Battery

New Power Wheels toys are supplied with lead-acid batteries. There are two good reasons for this. First, lead-acid batteries can withstand being overcharged, and second, they are far cheaper than similar capacity lithium-ion batteries.

Lithium-ion Phosphate Battery

A lithium-ion battery has one major valuable characteristic on Power Wheels toys. They can be deep-cycled to below 80% of their power rating and recharged without damage.

Lithium-ion batteries are more dominant than lead-acid batteries in terms of pros and downsides.

Battery Size

Lead-acid car batteries are classified into groups, which specify the battery’s physical dimensions. Check the size of your Power Wheels battery and find the right battery group using this size to battery group chart.

Connector

The safest way to connect your new battery would be to reuse the original Power Wheels connector if possible.

However, this would need some adaptation as a standard 12-volt battery will only come with two common connection terminals. Protecting the terminals is very important as a short circuit could cause the battery to catch fire.

Fuse

Original Power Wheels batteries have an internal fuse that protects against a short circuit. Putting a fuse on one battery cable is essential to protect against short circuits.

The Power from a 12-volt battery will not electrocute you, but a battery fire may cause severe burns. Make sure you cover any exposed terminals and connections.

Original Power Wheels batteries have short running times before they need recharging again. By fitting one of the alternative batteries listed below, you could increase the toy’s running time and save some money. 

What Alternative Power Wheels 12-Volt Batteries Are Available?

3 cheap alternatives to 12V power wheel choices are lawn mower battery, tractor battery, and deep cycle car battery.

Lawn Mower Battery For Power Wheels

Batteries designed for electric power lawnmowers are ideal as replacements for your Power Wheels battery. Just make sure the battery is the same voltage, has a similar or greater Ah rating, and fits the Power Wheels battery box.

The problem with using a lawnmower battery is that you will have to adapt the connector between the battery and the Power Wheels electrical system.

Tractor Battery For Power Wheels

If you are thinking of an electric tractor battery, they will work. Make sure you are using a deep-cycle battery, not a tractor battery designed to start the engine of a standard tractor. 

The electric tractor batteries are not designed to propel the vehicle quickly, so if you use them in a Power Wheels toy, you may see a decrease in performance.

Deep Cycle Car Battery For Power Wheels

A deep-cycle car battery is ideal as an alternative Power Wheels battery. Just make sure it fits the battery box and offers the same or more excellent power rating.

The biggest issue with standard deep-cycle car batteries is their weight. It is very tempting to upgrade the capacity when you get a new battery. Still, the added weight may cause steering problems, mainly if the battery is near the front.

Why Should You Buy The Miady LiFePO4 ?
