Lawnmower Battery 

In a perfect world, riding lawnmowers would always start when you turned the key, and they’d never run out of gas. But like everything else that has multiple working parts, it’s usually the battery that dies first.

Most riding mowers have a 12-volt battery, similar to the standard car battery only smaller, some even sport a 6-volt. The battery is responsible for creating the power needed to crank the engine. Each mower has an onboard recharging system that keeps powering the battery when in use.

Most of the lawn mower repair calls we get to our 4545 St. Johns Avenue, Jacksonville repair shop stem from a bad battery. If you are experiencing issues with your lawn mower’s battery not holding a charge, its good to have a basic understanding of the components of your lawn mower and what would be causing the battery outage.

Here are a few things to consider about the life of your battery:

  • Typically a lawnmower battery has a lifespan of about four years. When it comes near to the end of its lifespan, you’ll start to notice it doesn’t hold a charge for as long as it usually did. If you take into account how small the storage capacity is for a battery of that size, even the slightest change in the amount of power it holds could have a significant effect on its productivity. When your mower is not in use and if the battery is in good condition, it should be able to hold a charge for about three to four weeks. As the battery gets older, the hold-charge time will decrease. Often to the point where the battery will need to be replaced.
  • It’s good to understand the recharging system. The alternator and voltage regulator is responsible for recharging the battery. If at any point, one of those components fail, you would need to replace them to restore power to your battery. If those two parts are in good working order, you should aim to run your mower at full throttle to properly charge your battery. Even a slight reduction in the RPM’s will result in a reduction of the effectiveness of your on-board charging system. Resulting in the battery failing to hold a charge between mowings.
