Understanding the Issue
The Lawnmowers battery is mainly responsible for starting the engine alongside some battery-reliant devices inside the mower.
If the engine starts successfully, then the power required to run the electrical systems is produced by the alternator, powering the battery along the way too.
In other words, Batteries can provide, store, and receive electrical power once installed inside the lawn mower.
Since most mowers use 12-volt batteries, then our whole guide is made specifically for those mowers.
12V batteries are manufactured with 6 cells, each cell produces ~2.1V, amounting to ~12.6V, but it’s generally referred to as 12V worldwide.
Where can you find the battery? It depends on the mower’s model, but generally speaking, it can be found under the drink holder, behind the wheel, under the hood, or under the mower’s seat.
If this battery fails to start for the lack of power, then you’ll need to either refill, repair, replace, or jump the battery.
What to Check Before Trying to Jump the Lawn Mower Battery?
- Check that the battery is not leaking liquids of any sort.
- Terminals should not be damaged.
- Clean battery posts if they look dirtier than usual.
