Homelite cordless electric mowers use a 24-volt sealed battery system to power the mower. When the battery will no longer take a charge, it is time to replace the battery. Some Homelite mowers use two batteries instead of one. The batteries connect to each other with a cable. Unlike standard batteries that only have two cables connecting to the terminals, the mower battery will have several cables connecting to some terminals. It is a good idea to label the cables prior to removing them. Replacement batteries are available at Sears home improvement centers.
Remove the bolts securing the battery cover to the rear of the Homelite mower with a socket wrench. There are usually six hex-head bolts securing the battery cover. Lift the battery cover up and roll it toward the front of the mower, then rest the cover on top of the mower. There is a cable running from the battery cover to the battery that feeds the power indicator.
Place pieces of masking tape around all the cable ends connecting to the battery. Some Homelite cordless mowers use two batteries instead of one. There are cables that connect the two batteries together as well. Mark the cable positions on the masking tape with a pencil. This will help you reattach the cables correctly when installing the new batteries.
Remove the cables from the negative sides of the battery first. The negative terminals are black and have a "-" stamp near them. Remove the nuts securing the cables to the negative terminals of the battery with an open-end wrench. Disconnect the cables from the positive terminals on the battery. The positive terminals are red and have a "+" stamp near them.
Lift the battery or batteries out of the Homelite electric mower. Place the new battery or batteries in the mower. Connect the positive cables to the positive terminals on the battery. Look at the location markings on the masking tape to ensure you place the cables in their correct position. Secure the cables with the retaining nuts and bolts.
Secure the negative cables to the negative sides of the battery or batteries. Position the battery cover back over the battery compartment. Secure the cover to the mower with the retaining bolts.
