Best Lawn Tractor Batteries

It’s the last thing you need first thing in the morning – A dead battery. This is particularly true of lawn tractor batteries, whether the tractor is tasked with plowing snow or mowing grass before a rain. The best lawn tractor batteries have sufficient strength to last through a hard job, and can maintain their charge even while not in use. Extreme cold weather tends to present a challenge, as does intermittent use. Years ago, folks would remove batteries and connect them to a trickle charger, but as machines continue to get bigger and more complex, sometimes this can be a chore as they’re buried deep within the works and removal is nearly impossible.

That said, the best lawn tractor batteries come from a variety of manufacturers and nearly all can be found online for competitive prices. When shopping around, consider the Ah factor, which represents the “ampere hour,” meaning the amount of energy charge in a battery that will allow one ampere of current to flow for one hour.

Below we look at five of the best lawn tractor batteries available today, along with some battery maintenance tips so you can get your current battery to last for many years to come.

Maintaining Lawn Tractor Batteries

NOCO Genius 5 Battery Maintainer

When it comes to maintenance of lawn tractor batteries, a little work can go a long way. One helpful tool for this is a battery maintainer. Not to be confused with the trickle charger, this machine uses a high-frequency pulse which, over time, helps dissolve some of the sulfates, which effectively restores the lead plates. Homeowners would be most interested in solar-powered maintainers for storage sheds where no outlets are available.

Other points, which every lawn tractor owner knows, include cleaning the battery of dirt and residue regularly. This is particularly important with lawn tractors which can accumulate a packing of dead grass and dust over time. Checking water levels in each cell is also helpful, and make sure the charge is maintained, particularly throughout the winter months.

Proper maintenance, paired with any of these high-quality lawn tractor batteries, can go a long way to ensuring a good operation whether on the farm, or at home.
