Deep Cycle Lawn Mower Battery

You can’t use any lawn mower battery on Power Wheels because some cannot handle the toy cars’ demand. It would be best if you had a deep cycle lawn mower battery that can withstand being charged repeatedly during the lifespan of the toy. 

A deep cycle lawn mower can be recharged hundreds of times before it goes bad. Additionally, it can discharge 20-50 percent of its energy to fuel Power Wheels on various terrains.

A deep cycle lawn mower battery is a close fit to the deep cycle battery for power wheels from the manufacturer. 

Voltage

You need to ensure that the lawnmower battery’s voltage is the same as that of the Power Wheels. Meaning, a 12V lawn mower battery should go to the 12V Power Wheels toy cars for kids. 

Likewise, a 6V lawn mower battery is compatible with 6V power wheels. It is a different process to upgrade a power wheels battery from 6V to 12V. 

The voltage of a battery is essential because the wiring and motor for Power Wheels depend on it. A higher voltage than intended for the toy cars can lead to malfunction because it isn’t equipped for that much power. 

If you feel the vehicle could use more power you can also do a motor upgrade on a Power Wheels.

Battery Size

Sometimes you will find that a lawnmower battery can fit into space where the power wheels battery goes in place. However, most of the time, parents have to make adjustments to the space to accommodate a lawnmower battery. 

You need to take the battery’s measurements in the car and the lawnmower battery to know how much space you need. 

You can use a power saw to cut through the battery and create more space in the vehicle’s hood. The goal is to ensure that the hood locks appropriately once the new battery is in place.

You can find a battery box for the new battery after making the necessary adjustments. 

Connectors 

A lawnmower battery isn’t connected the same way as Power Wheels batteries. Most power wheels use connectors to attach the battery to the wiring system.

You will need connectors or crocodile clips to hook up the battery terminals to the toy vehicle. 

You can find connectors and crocodile clips at the local store. Just make sure that you get the right wiring size that can carry the current without burning out.

Power Wheels 12 Volt Battery Conversion

You will need a power saw, a screwdriver, wire strippers, and some pliers to convert power wheels to a lawnmower battery. 

Ensure that you do the conversion in a location that has ample space for moving around the car. The batteries in most Power Wheels are at the front, but some are back.

So the following steps for the conversion process. 

  • Pop up the hood of the car and remove the battery of the toy vehicle. Store the battery for appropriate disposal at a later time. 
  • Take the battery container of the lawnmower battery and outline the hood to create adequate space for it. Most lawnmower batteries are usually larger than those of Power Wheels ride-on kid’s cars. 
  • Cut out more space in the battery area using the power saw. Take time to fit the battery to see whether it has adequate room and the hood can close correctly. Make the small segments’ adjustments to avoid creating an extra-large space that can hold the battery in place. 
  • Once the battery can fit it properly, it’s time to connect the battery to the car’s system. Mark the negative and positive wires in a manner that is easy to identify. Cut out the plug on the Power Wheels and dispose of it.
  • You have to strip about two inches of insulation off the positive and negative terminal to hook them up to the connectors. Ensure the battery’s positive terminal is connected to the positive wire and vice versa for the negative terminal. 

Once you are done with the conversion, it is time to test the vehicle and see how the new battery performs. Have one of your kids take the toy vehicle for a spin around the yard or the neighborhood. 

Ensure that they try it out on different landscapes like slopes, hills, grass, gravel, rough roads, and tarmac. It will work seamlessly and have enough power to go over all the landscapes above.
