How to Charge a Lawn Mower Battery Without a Charger?
It is likely that your lawn mower’s battery might drain out or get damaged, especially if it has been stored for a long time. In such a case, is it possible for you to charge its battery with a car battery charger? How do you go about doing that?
It is possible for you to charge a lawn mower battery with a car battery charger. You can do this by simply attaching the cables of the car battery charger to the lawn mower battery and then connecting the charger to a power outlet. Remember to use the appropriate voltage and output settings for this.
In order to do this correctly, however, there are several things that you must keep in mind to ensure good functioning as well as safety. Read on to find out the entire process.

How Can I Charge a Lawn Mower Battery with a Car Charger?
If you have a car battery charger at your disposal, you can use it to charge your lawn mower battery by following a simple process.
Having a modern battery charger will prove to be even more convenient as it will allow you to make use of helpful features that include switching to different modes, turning off by itself when the charging is complete, using various clasps and more.
You must, however, first ensure that the voltage and output levels of the car battery charger are compatible with the lawn mower battery. For instance, setting the voltage to 12 volts would be a good idea since recent lawn mowers tend to have that as their voltage.
Similarly, an output of 10 amps or lesser will be sufficient. This is to make sure that a higher output does not end up overcharging the battery. Even though using fewer amps might take longer, it will definitely improve the charging technique.
Take a look at the steps that you must follow for carrying out this task.
Step 1: Unplug the Charger
You should remember to disconnect the car battery charger from its outlet so that there are no safety issues while connecting the charger to the mower. You should also wear some protective equipment like gloves and glasses to stay safe.
Step 2: Locate the Mower’s Battery
You will need to figure out where the lawn mower’s battery is. If you are doubtful about the location, you can simply seek the information from the user guide that came along with your lawn mower.
Step 3: Connect the Charger
In order to connect the car battery charger to the mower’s battery, attach the red cable lead to the positive end of the battery and then the black cable to the negative end.
Step 4: Confirm the Voltage
Make sure you confirm that the charger’s voltage matches that of the lawn mower’s battery. Generally, this will be 12 volts. This is an important step that will help you maintain efficiency as well as safety.
Step 5: Plug the Charger In
Once you have successfully completed the aforementioned steps, you can plug your car battery charger back into the power or electrical outlet and turn the switch to the outlet on.
Step 6: Let It Charge
If you have a 10-ampere charger, you can expect a charging and waiting period of an hour until your lawn mower’s battery is fully charged. If the output is lower than 10 amps, it might increase the amount of time that it takes to complete charging to several hours at a time.
Step 7: Disconnect
You can then disconnect the charger from the battery by removing the black cable first followed by the red cable. This will conclude your process, following which you can start using your lawn mower again.
It would be a good idea to test out the mower first for a minute before using it in a full-fledged way. You should also let it run for a certain time period so that you can confirm that it is working well.
Frequently Asked Questions
Can You Charge a Lawn Mower Battery with a 12-volt Charger?
Yes, you can charge a lawn mower battery with a 12-volt charger. In fact, newer models of lawn mowers tend to have a voltage capacity of 12 volts, making a 12-volt charger ideal for this process.
You might also have a charger that lets you switch between different voltages. In such a case, you can simply change the setting to 12 volts.
Can You Recharge a Dead Lawn Mower Battery?
You can certainly recharge a dead lawn mower battery. You simply need to follow the method we highlighted above. Since the lawn mower battery was dead, it might take a bit longer to recharge fully before you can use it.
If this doesn’t work, you can try the method described in the next answer or you can simply call a professional for help.
Are There Any Other Ways to Charge a Lawn Mower Battery Using a Car?
Yes! Another way to charge a lawn mower battery using a car is by jumpstarting your lawn mower. This requires you to directly connect the battery to the battery of your car.
In order to do this, you should place the mower and car close to each other and then attach the red and black cables to the batteries (red ones to the positive terminals and black to the negative). You can then test it out by turning your lawn mower on.
If it doesn’t turn on, try to wait for a while before testing it out again. You can then disconnect the cables once it starts working (remove the black ones first followed by the red ones).
If this doesn’t work either, you can specifically invest in a lawn mower battery charger. You can also ask a professional to fix it up for you.
Using a trickle charger to make the charge last longer with a steady trickly can also be a good idea. Further, you can also buy a portable jump starter or simply use a screwdriver to get the engine going.
When Is the Best Time to Charge a Lawn Mower Battery?
Generally, you should charge a lawn mower battery right before keeping it for storage during the months of winter. This should ensure that the mower does not run out of too much battery during the cold season.
You should also do this right after winter after taking the mower out from storage. This will make it work efficiently when you use it again. If for some reason, your lawn mower runs out of battery or dies out, you will need to charge it again.
Can You Charge a Lawn Mower with a 6-volt Battery Charger?
Lawn mowers that come in newer models (usually after 1980) tend to come with a voltage setting of 12 volts. For this reason, it would be better for you to use a 12-volt charger and not a 6-volt charger.
However, if you own a functional lawn mower that is an older model, you should check the voltage setting. If it says 6 volts, then you are safe to use a 6-volt battery charger.
Are There Any Ways to Make Your Lawn Mower Battery Last Longer?
Luckily, there are several ways that you can make good use of to make your lawn mower battery last longer. Some of these include:
Using a trickle charger so that the charge is drawn out without overcharging concerns. This can also make the charge go on for a long time.
Cleaning up the batteries to prevent a build-up of rust or corrosion. You should do this on a regular basis to prevent issues.
Regularly servicing your lawn mower to fix minor issues.
Ensuring that you maintain similar voltage settings at all times while charging.
Using your mower on a regular basis or keeping it in good conditions while storing it in the winter.
