How Long Do Electric Lawn Mowers Last?
Electric lawn mowers are rapidly becoming the go-to choice for gardeners seeking efficiency, eco-friendliness, and lower maintenance. But just how long can you expect these mowers and their batteries to serve your yard? Let’s dig into the details, covering battery lifespan, care tips, troubleshooting, and how to choose the best battery for your mower.
Electric Lawn Mower Lifespan
With proper care, electric lawn mowers typically last between 8 and 15 years. Their longevity depends on build quality, frequency of use, and, most importantly, battery maintenance. Unlike gas mowers, electric models have fewer moving parts, so you’ll spend less time and money on repairs. However, the battery is the heart of your mower, and its lifespan will often determine when you’ll need to replace or upgrade your equipment.

Types and Longevity
There are several types of batteries used in electric mowers, each with its own pros and cons:
-
Lead-Acid Batteries: Affordable and reliable, but heavier and require more maintenance. Expect 3–4 years of life with good care.
-
Lithium-Ion Batteries: Lightweight, fast-charging, and can last up to 5–10 years with proper maintenance.
-
Nickel-Cadmium (NiCd) Batteries: Less common today due to environmental concerns, but still found in some older models.
A lithium battery for lawn mower use is now the standard for most modern cordless models, prized for its durability and quick charging.
How Long Does a Lawn Tractor Battery Last?
For riding mowers and lawn tractors, battery lifespan is similar: lead-acid batteries last around 3–4 years, while lithium-ion options can stretch to 5 years or more. Regular charging and proper storage will help you reach the upper end of these ranges.
Does a Lawn Mower Battery Charge Itself?
No, a lawn mower battery does not charge itself25. For cordless models, you must remove the battery and place it in the charger after each use. Even riding mowers with alternators may not fully recharge the battery during short mowing sessions, so periodic charging with an external charger is recommended.
Can I Leave Battery in Lawn Mower?
It’s best to remove the battery from your mower if you won’t be using it for an extended period, especially during winter storage. Store the battery fully charged in a cool, dry place to prevent capacity loss. Leaving the battery in the mower can lead to slow discharge and corrosion, shortening its lifespan.
Lawn Mower Battery Drains When Not in Use
If your lawn mower battery drains when not in use, it’s often due to small parasitic draws from the mower’s electronics or natural self-discharge, especially in older or damaged batteries. Over time, all batteries lose charge, but if you notice rapid draining, check for dirty terminals or replace the battery if it’s several years old.
Symptoms of a Bad Lawn Mower Battery
Watch for these common symptoms of a failing battery:
-
The mower won’t start, or only clicks.
-
The engine cranks slowly.
-
Headlights (if equipped) are dim or flicker.
-
The battery won’t hold a charge.
-
Visible corrosion or swelling on the battery.
If you spot these signs, it’s time for troubleshooting or replacement.
Are Traveller Batteries Any Good?
The search results do not provide specific information about Traveller brand batteries, so it’s best to consult user reviews and manufacturer specs before purchasing. Always compare warranty terms and user experiences for peace of mind.
Lawn Mower Battery Size
Choosing the right lawn mower battery size is crucial. Check your mower’s manual for voltage (usually 12V, 20V, 40V, or higher for riding mowers), amp-hour (Ah) rating, and physical dimensions. Using the correct size ensures optimal performance and avoids damage to your mower.
Lithium Battery for Lawn Mower
Lithium batteries are the top choice for most modern mowers. They offer:
-
Lighter weight for easier handling.
-
Faster charging (often within an hour).
-
Longer lifespan-up to 10 years with proper care.
-
Less maintenance compared to lead-acid batteries.
These features make them ideal for both push and riding mowers.
Best Riding Mower Battery
The best riding mower battery will depend on your mower’s requirements, but lithium-ion batteries are increasingly popular due to their longevity and low maintenance. For lead-acid models, choose a reputable brand with the correct cold cranking amps (CCA) and amp-hour rating as specified by your mower’s manufacturer.
Caring for Your Mower’s Battery
Proper care can significantly extend your battery’s life and keep your mower running smoothly. Here’s how:
1. Charge After Every Use
Always recharge your battery after mowing. Avoid letting it fully discharge, as deep discharges can damage both lead-acid and lithium batteries.
2. Clean the Terminals
Inspect and clean battery terminals regularly using a baking soda and water solution to prevent corrosion, which can impede performance.
3. Store Properly
If storing your mower for weeks or months, remove the battery and store it fully charged in a cool, dry place. For lead-acid batteries, check water levels and top up with distilled water if needed.
4. Inspect for Damage
Look for signs of swelling, leaks, or corrosion. Replace the battery if you see any of these issues.
5. Avoid Extreme Temperatures
Don’t expose your battery to high heat or freezing cold, as this can reduce its lifespan and performance.
Final Thoughts
Electric lawn mowers offer years of reliable, eco-friendly service with proper care. Pay close attention to your battery-choose the right type, keep it clean, charge it regularly, and store it correctly. By following these tips, you’ll enjoy a lush, well-manicured lawn season after season, with fewer breakdowns and more time to enjoy your garden.
