Remove the Surface Charge

First of all, you need to remove the surface charge if you want to test the battery in your ride-on toys. It is essential to remove the surface charge because it can make a good battery like a bad or bad battery look good if you don't do that.

You can allow the battery for 4 to 12 hours to sit in a warm room to remove the surface charge around 77° F. Once the surface charge is removed, you can measure the battery charge with a hydrometer. The certain gravity should be 12.65.

Method 2- Load Test on Your Battery:

Load Test on Your Battery
If you want to know your battery's condition, you might need to perform the load test. You can use a load tester to test the battery. If it is off by 20% to 50%, that is a very significant amount and can make a huge difference in knowing if the battery is good or bad.
  • If the battery charge is 75% or higher, you can make a load test on your power wheel battery.
  • You want to apply a load equivalent to one half of the cold-cranking amps rating for 15 seconds with a battery load tester.
  • Then apply one-half of the cold cranking amps of the power wheel for 15 seconds.
  • Turn the engine over for 15 seconds and disable the ignition with a starter motor.

Voltage should not drop below 9.6 during this test. You can recharge the battery as early as possible to prevent sulfation if the battery has passed the load test. It will restore the battery to its perfect condition.

Method 3- Test Your Battery with a Power Probe:

Test Your Battery with a Power Probe
  • Remove the positive terminal cover of the battery
  • Attach the positive lead of the power probe to the positive terminal on your battery. Usually, the voltmeter's positive lead is red.
  • Connect the negative lead of the power probe to the negative battery terminal.
  • Attach the probe's point to the positive battery terminal and test the probe for voltage reading.
  • Check the power probe reading. The voltage should be between 12.4 to 12.7 volts if your battery is in good condition.

Method 4- Test Your Battery by Starting the Engine:

Test Your Battery by Starting the Engine
  • Start the engine by turning the ignition until the starter participates in and holds for 2 seconds. You can take an assistant to start the engine and test the battery voltage drop.
  • During the engine start, test the reading of the power probe, which shouldn't go below 9.6 volts.
  • A power wheel battery with a volt reading less than 9.6 volts implies that the battery is sulfated and not taking charge.

How Long Should A Good Power Wheel Battery Last?

The battery life of a car varies depending on different factors. The most significant points are how you follow the charging and battery maintenance instructions. Besides, the use of batteries has a considerable impact on knowing the life expectancy of a Power Wheels battery.

According to the Fisher-price, the average battery life of a ride-on toy car is 1-3 years.

However, depending on the manufacture and how long it remained in the shop unused, a good power wheel battery lasts for nearly 4 to 5 years.

How Long Does a Fully Charged Power Wheels Battery Last?

It would be easier for you to know how long your child can play when you get the possible answer, "How long does a fully charged Power Wheels battery last?"

Well, according to the automotive experts, the lasting period of your fully charged Power Wheels battery will depend on the two main factors, including:

  • The model of power wheel ride-on toys and
  • The riding mode or speed mode (how fast they ride the car)

Based on these two factors, a fully charged Power Wheels battery will last approximately 45 to 90 minutes.

Besides, the average time relies on different features such as the rider's weight and the road conditions that can regulate the speed modes.

Usually, a child with a Dune Racer that futures 2.5 MPH mode will last a bit longer than a 5 MPH mode vehicle.

What Causes A Battery to Be Almost Dead?

What Causes A Battery to Be Almost Dead

If your power wheel battery doesn't work accordingly, you don't need to worry that the battery is dead.

1. One of the most common reasons for making the battery to be almost dead is long time immobility. Leaving the toy cars in the garage for a long time, winter to spring, can damage the battery. However, it doesn't mean that you need to buy a new one.

What makes your battery dead if you don't use it for a couple of months? Although before garaging the car, you charge it fully, the automatic discharge ratio will increase and goes to zero within 3 to 4 months.

2. Overcharging a battery or charging a battery for a long time can cause it to be almost unresponsive.

3. Charging the battery after a long time break can also make it dead.

Power wheels batteries are meant for the optimal useful life of around three to four years, provided you employ the off-season's ideal maintenance. The actual useful life, as reported by users, is around one to two years.

Tips and Tricks to Avoid Having an Almost Dead Battery:

Let's take a look at some tips and tricks to avoid having a nearly dead battery:

  • Don't charge the battery for more than twelve to fifteen hours.
  • Before garaging the car for a long time (3 to 4 months), remove the battery.
  • Every 2-3 months, charge the battery up to 8 hours to avoid the natural discharge rate.

How to Tell If The Power Wheels Battery Is Charging Or Not?

Are you worried to know why your power wheels battery isn't charging? Firstly, you should find out if the battery or the charger itself is the issue. Here we go through how to test both battery and charger.

Things You Need:

  • Power Wheels charger
  • Power Wheels battery
  • A voltmeter and
  • 2 paperclips

Testing the Output Of Your Charger:

  • Change the voltmeter to the 20 dc power supply area.
  • Join the electrodes to the ride on toy battery charger (positive to positive and negative to negative)
  • Always, you will demand that the voltage is higher than the battery. It implies that if you have a6v battery, then it needs 7+ voltages. On the other hand, if you have a 12v battery, the voltage needs to be over 13.5.
  • Anything below these voltages can't charge your battery.

Testing the Battery:

  • Testing the power wheel battery is the same as how you test the charger. Set the electric conductor against the battery (positive to positive and negative to negative).
  • The charging will not work if the battery is under a specific lower limit.
  • The 12-volt battery needs to be at 10.5v+, and the 6 volt needs to be over 5v +. You should change the battery if the volt is lower than the given ratio.

It is a bit tricky to test the red power wheel battery because the electric conductor wouldn't fit into the slots. Firstly, you need to insert the paperclips and then keep the conductors next to them against the battery.
