How Long Does An Electric Lawn Mower Last?

Buying a new electric lawn mower typically involves a high upfront cost (which is one of the biggest downsides to buying electric, by the way). So, naturally, you'd want to be aware of its average lifespan to make an informed decision. Generally, a decent model should last around seven years to a decade, thanks to its durable electric motor and mower deck. That being said, the battery is a quintessential part of an electric lawn mower, and it typically lasts three to five years. This means you'll have to replace it at least twice over the course of your equipment's life.

However, its exact lifespan depends on the usage, care, climatic conditions, and, more importantly, on the type used. For example, lead-acid batteries are heavy and cheap, but they usually don't last more than two to four years (or after it's charged 300 to 500 times). And that's if it's maintained really well. Lithium-ion is another popular variant. It weighs less, performs better than the lead-acid ones, and lasts for three to five years (or 500 to 800 charging cycles). You'll also find LiFePO4 (lithium iron phosphate) batteries in use, but they're restricted to a few advanced models (like the Mowrator S1 4WD Remote Control Lawn Mower). They're pricey but durable and can be used for over 10 years (as they can withstand 2,000 to 4,000 charge cycles). Having said this, it's worth acknowledging that proper care and maintenance of the appliance would also help ensure there aren't any hiccups along the way.

Your electric lawn mower has a certain life expectancy and it'll run its course one day. But that doesn't mean you can't take a few measures to extend its life by adequately maintaining its key component: the battery. Always follow the instructions in the mower's manual to charge it sufficiently. Wiping down the charging ports and contacts regularly is necessary, too. Plus, once the mowing season is over, it's important to store your device properly. To get your tool hibernation ready, simply follow a few steps: allow it to dry completely, ensure your mower holds 40 to 60% charge, and store it in a cool and dry place to protect it from extreme temperatures and sudden rainfall.

However, sometimes instead of maintenance, your device might actually need a new battery. To illustrate, if you notice that it's getting discharged within a few minutes of charging or takes absurdly long to recharge, it's a clear sign that your battery has lost its capacity to hold energy and must be replaced. Alternatively, if your device now needs to be charged several times to mow the same lawn, you might want to invest in a new battery. The most alarming indicator is a distended battery. In case you find yourself in this situation, stop using your equipment immediately and dispose of the old battery with caution (and per your county/local government rules) before installing a new battery in your lawn mower.
