A lawn mower is an indispensable garden tool every homeowner should have, and you need a lawn mower battery to keep it running. This device works wonders in trimming stubborn hedges in your garden. While this tool is sturdy, there are times when your lawn mower stops working due to weak battery. While gas and oil mowers are very easy to work with, replacing a lawn mower battery is another thing. To begin, it is important that you take note that each battery is only specific to a particular type or model. Follow the steps below to do this project on your own.
Tools and Materials
- Lawn mower battery (as specified by the brand of the machine)
- Lawn mower’s manual
- Screw drivers
- Socket and ratchet set
- Baking soda
- Wire brush
- Working gloves
Step 1 - Turn Off the Lawn Mower
Before you pry loose the lawn mower battery, it is important that you first turn off the lawn mower. Moreover, you also need to wear the right gear such as a pair of working gloves to protect yourself, particularly your fingers.
Step 2 - Locate the Battery
The battery of lawn mowers are located either under the hood or under the mower’s seat but just to save time when it comes to locating your lawn mower battery, you can always refer to the lawn mower’s manual that is included when you first purchased the device. Once you have located the battery, look for the release latch so that you can easily access the battery and then remove the strap or anything that holds the battery in place so that you can take it out.
Step 3 - Clean the Battery Connectors
Once you have removed the strap, you will still not be able to remove the battery just yet due to the battery cables that are screwed onto it. These battery connectors are usually corroded so in order to bring back the efficiency of the battery, use a baking soda paste and carefully dab it to the corroded part. Let it sit for several minutes before you scrub the terminals with a wire brush to remove the rusts. Once done, dry it off with a clean rag. Now while doing this procedure, make sure that you do not mix the baking soda with the battery cells; otherwise, it will render the battery ineffective. Once the rusts have been removed, carefully remove the battery by prying the cable loose with a screwdriver.
Step 4 - Replace the Old Battery with a New One
After the battery has been removed from the holder, rinse the battery holder from any debris and corrosion. Use the baking soda paste for this purpose. Let the battery holder dry before you place a new battery back into the holder. Once the battery holder has been in place, use the socket and ratchet set to firmly hold it in place before you attach the strap that secures it in place.
