Now since you know that the fault is in your battery, you must be thinking about how to install a new battery to clean your yard.
Here are a few steps, just follow them to replace your old battery with a new one.
- If your battery got finished while you were using it then make sure your Lawn Mower is parked on a level surface.
Let the blades and all moving parts come to a complete halt after turning off the engine. Allow a few minutes for the lawnmower to cool.
- Now inspect your Lawn Mower and look for the battery. The battery in a Lawn Mower can be found behind the seat or under the hood.
- To protect yourself from battery acid, put on protective glasses and gloves.
- There are chances for corrosion in your lawn mower battery, especially the point that connects the battery cables to the terminals. To dissolve any corrosion prepare a baking soda mixture.
- To prepare the baking soda mixture, add 1 cup of water, 1 tsp of baking soda in a disposable cup. Thoroughly mix the contents with a spoon to dissolve the baking soda.
- Then, insert a flat-head screwdriver into the battery-stabilizing bracket, if your lawnmower has one. To release the screw, turn it counterclockwise and move the bracket to one side.
- To loosen the negative terminal, insert an adjustable wrench on it and turn it counterclockwise. The black battery line is linked to the negative terminal, which has a “-” sign on it.
In the same way, detach the positive, red battery cable. Remove each battery cable from the old battery by pulling it up and out. Now remove the old battery from the battery box and set it aside using the middle handle.
- Each battery cable should have the pointed end of a battery terminal cleaner inserted into it. To remove any rust or corrosion that is preventing the battery from performing correctly, turn the cleaner in a circle.
Each cable should be cleaned until the insides of the circles are gleaming. Now use a shop towel, wipe away any excess metal shavings.
- Fill the box with the new lawnmower battery. Add a thick layer to the new battery terminals with a forefinger dipped in petroleum jelly. The fresh battery will not corrode as a result of this.
- Use an adjustable wrench to tighten the red positive battery connection to the positive terminal. In the same way, change the black negative terminal.
- To keep the battery bracket in place, replace it and tighten the screws clockwise.
