Can You Jump Start a Lawn Mower Battery with a Car Battery?
It is possible for you to jumpstart a lawn mower battery with a car battery. In order to do this, you can follow the steps mentioned below.
Step 1: Choose a Location
You should make sure that your lawn mower, as well as your car, are kept close to each other. This is to ensure that the jumper cables you use can connect well to the terminals of both. Since you want to minimize the distance, the best position would be to place the car right behind the mower.
It would be more convenient for you if you place both on even ground so that access to both becomes much easier.
Step 2: Prepare Your Mower
You can prepare your mower by first figuring out where the lawn mower battery is located. This might be under your seat, but if you are unsure about its location, you can easily look through your user manual to figure it out.
If there are any covers over the batter or over any other part, you should remove them so that they don’t get in the way.
Step 3: Prepare the Car
You should do this by switching the car’s engine off in the first place. You can then open up the hood and remove any covers nearby. It is important for you to turn off the engine so that you can prevent overloading as this could otherwise cause plenty of damage to the batteries and to yourself.
Step 4: Wear Safety Equipment
You must protect your own well-being as well by wearing the relevant safety equipment. Gloves, masks and some glasses to protect yourself should be enough. This is to ensure that acid from the batteries does not come into contact with your body.
This can also be a good way to protect yourself to a certain extent from electric shocks. Further, you should remember to not stand too close to the engines as well while carrying out the process.
Step 5: Clean Up the Batteries
In both your car as well as your lawn mower, you should clean up the batteries in case there are any corrosive elements on them. In order to do this, you can mix some baking soda and warm water. You can also simply use a brush, cloth or steel wool.
While doing this, it is important to ensure that you don’t end up causing scratches or further damage to the batteries.
Step 6: Check the Voltage
It is necessary to confirm that the batteries are compatible with each other. For instance, a 12-volt car battery should only be used with a 12-volt mower battery. This shouldn’t be too much of an issue as most modern lawn mowers come with this voltage setting.
If there is a difference in voltage settings, you might need to look for different methods to help you out.
Step 7: Connect the Cables
The jumper cables will come in two colors: black and red. The red one is the positive cable with should be connected to the positive terminals of both the car battery as well as the lawn mower battery.
The black cable should be connected to the negative terminal of the car battery. The other end of this cable should be placed on a metal surface that is located at a certain distance from the batteries.
Step 8: Start the Engine of the Mower
You should turn on the lawn mower’s engine so as to check whether the jumpstarting process worked successfully. Make sure to leave the engine of the car off at all times during this process.
In case the lawn mower still does not work, you should keep the cables connected for a while and then try again later.
Step 9: Disconnect the Cables
Once your mower starts working, you can then disconnect the cables in reverse order. Remove the black cable first and then move on to detaching the red cable.
Step 10: Try It Out
You should let your lawn mower run for a while so that it can get charged up again, especially if it hasn’t been in use for a long period of time.
Can You Jumpstart a Riding Lawn Mower with a Car Battery?
You can jumpstart a riding lawn mower with a car battery using the same method described above. This means that you must make all the necessary preparations, check voltage settings, connect the cables and test it out.
In case this method does not work, there are other options that you can try out. If not, you can also buy relevant equipment or call a professional to help you out.
How Long Will the Whole Process Take?
Provided that you have assembled all the necessary equipment, the subsequent steps of cleaning up, connecting cables and starting the mower’s engine should not take you longer than a few minutes.
After it starts up, however, you should let the engine run for at least half an hour to allow it to charge up again.
Frequently Asked Questions
Can You Jump Start a Lawn Mower without a Battery?
Yes, it is possible to jumpstart a lawn mower without using a car battery. There are several ways to do this:
You can use a car battery charger of compatible voltage and output settings by connecting its cables to the lawn mower battery and then connecting the charger to a power source.
You can use a trickle charger by once again connecting the red and black jumper cables of the charger. This will take a longer time but will prevent overcharging.
You can buy a portable jump starter that will only require you to connect cables to the lawn mower battery.
How Do You Jump Start a Lawnmower with a Screwdriver?
If you want to jumpstart a lawn mower with a screwdriver, there are two ways in which you can do this:
You can simply insert the screwdriver into the keyhole of the lawn mower and turn it on.
You can locate the battery and use the screwdriver to connect the positive and negative terminals. This should ideally turn the engine on. You can try a few more times if it doesn’t work right away.
Make sure you wear protective equipment for this method.
How Can You Keep Your Lawn Mower Battery Running for a Long Time?
You can keep your lawn mower battery running for a long time by undertaking regular care and maintenance of the mower. This includes cleaning up the batteries on a regular basis in order to get rid of corrosive build-ups, using a trickle charger to ensure that the charge is steady and long lasting and lastly, using your mower regularly.
If you do not possess a trickle charger, you can easily buy one. You can also make use of a regular charger if you need to use your lawn mower immediately and frequently.
While charging, you should further maintain the voltage compatibility at all times.
When Is It a Good Time to Jumpstart a Lawn Mower Battery?
You can jumpstart a lawnmower right before and after storing the lawn mower through the winter. This is to ensure that it doesn’t completely discharge.
If your battery dies out, you can use this technique as well. In case chargers don’t work or are not easily available, this can be a good method to try out.
