You can help protect your battery by covering its terminals. You don’t want to leave your battery somewhere super humid or wet.Ĭleanliness matters too. Making sure that your battery is clean and dry are the two most important things that come to mind. However, there are a couple of other things to consider. Monitoring charge during this time is key, and so is putting the battery somewhere with the right temperature. Since most people don’t mow all year round, the battery should be stored properly when not in use. Knowing how (and how not) to store a battery requires you to know about both charging and temperature. Keeping your lawn mower battery at a moderate temperature will help it live longer. Sure, a lot of people know about restoring a lawn mower battery, but you can only do that process so many times. If your battery is always sitting out in the sun its electrolyte solution could be evaporating and its capacity could be lowered. By very hot, I mean over 100 degrees Fahrenheit. Lawn mower batteries also don’t like very hot temperatures. If you leave your lawn mower battery in your mower over the winter it’s really easy for it to become discharged and could possibly freeze. Speaking of winter, extreme temperatures can hurt batteries.

Allowing a battery to sit in a discharged state will also negatively affect its lifespan.īeing sure to keep a full charge on your lawn mower battery (even in the winter when it isn’t being used) is really important. Just like overcharging causes problems, so does leaving a battery undercharged. Using a trickle charger or battery maintainer really helps extend the lifespan of batteries. Overcharging is really bad for batteries and can even be a fire or explosion hazard. This occurs when using a battery charger that supplies a lot of voltage at a time, or doesn’t shut off when the battery reaches a full charge. I find that a lot of people ask if you can overcharge a lawn mower battery. Here are some of the biggest things that will affect how long a lawn mower battery can last: Charging You can get away with using your lawn mower battery a ton, but you should be sure to avoid common battery care mistakes. I know that I’ve said that your lawn mower battery will last for years and years, but that is really dependent on how well it is cared for. Factors That Impact How Long a Lawn Mower Battery Lasts The catch here is that they need to be taken care of correctly. Usually 3 to 4 years for lead-acid batteries, and up to 5 years for most lithium-ion mower batteries. When all is said and done, lead-acid batteries in riding mowers and lithium-ion batteries in either push or riding mowers can last pretty close to the same amount of time. Gas-powered push mowers don’t use a battery, they typically use a magneto to get started instead. These batteries are what actually supply all of the power to the mower, turn the blades, and get the grass cut.Ĭordless electric push mowers use lithium-ion batteries as well. Riding mowers with electric motors use lithium-ion batteries. Some older models use 6-volt batteries but it isn’t as common. Nowadays, this will almost always be a 12-volt battery. Gas-powered riding mowers use lead-acid batteries to get the engine started.
The first question to answer when it comes to riding mower batteries is, are we talking about a riding mower with a gas or electric motor? I’ve noticed that a lot of people want to know how battery life expectancy changes depending on the type of lawn mower. Differentiating Between Riding Mower and Push Mower BatteriesĪnother good way to provide some clarity about battery life is to talk about how long does a riding lawn mower battery last versus how long does a push lawn mower battery last. Most battery-powered mowers have lithium-ion batteries that can typically be expected to function for up to 5 years or 500 charging cycles. With proper care, a lead-acid lawn mower battery should last about 3 to 4 years. If your lawn mower has a battery, it will either use a 6 or 12-volt lead-acid battery or a lithium-ion battery. 4.2 How long does a 12-volt lawn mower battery last?
