How to Stop a Battery From Being Drained on Lawn Mower While Not in Use
- 1). Double-check the ignition and light switches (if equipped). The batteries in lawn mowers are similar to car batteries; if something is left on, the battery will drain down quickly because the alternator isn't operating to keep the battery charged.
- 2). Store the lawn mower in a garage or shed during winter. Extreme cold can reduce the power of your battery, increasing the chances of its draining down.
- 3). Disconnect the battery when the lawn mower is not in use. If the battery is connected, a small amount of energy is being used; this can quickly drain your battery if you use your lawn mower infrequently. Remove the negative (-) battery cable first, and then remove the positive (+) battery cable.
- 4). Clean the battery terminals if they are corroded or dirty. Unhook the cables and use a wire brush to scrub the battery terminals until they are clean. Do not use solvents or liquid to clean your battery terminals. Wipe the terminals with a dry cloth when you are finished.
