One of the most important parts of a lawn mower is its battery. Lawn mower batteries can last for years but how long do they really last?
A good lawn mower battery can have a lifespan of up to five years. However, there are a variety of factors that can influence a lawn mower battery’s life, including maintenance.
In this article, we find out how long the different types of lawn mower batteries can last and how you can extend the life of the battery.
How Long Does A Lawn Mower Battery Last?
As a rule of thumb, a lawn mower’s battery can last between three and five years. However, some batteries stop working after one year, while others work for much longer than five years.
Batteries in lawnmowers hold a charge, and the capacity for holding this charge decreases over time.
There are many different factors that affect how long your lawn mower’s battery lasts, including the type of battery, the storage temperature and battery maintenance.
Different lawn mower battery types have different lifespans.
Lifespan Of A Lithium-Ion Battery
Lithium-Ion batteries in a lawn mower can last for up to 5 years. This translates to 500 charging cycles.
This means the more often you charge your lithium-ion battery, the sooner your battery will stop working.
The lifespan of your lithium-ion
Lifespan Of A Lead Acid Battery
Lead-acid batteries are one of the most commonly used battery types in lawnmowers. These batters can last between 1 and 3 years, which is around 300 charging cycles.
Lead acid lawn mower batters are commonly used in cold climates where they are much more resilient to cold temperatures than lithium-ion batters.
However, cold temperatures can affect the charge-holding abilities of your lawn mower battery.
Factors That Impact The Lifespan Of A Lawn Mower Battery
While a lawn mower battery can work perfectly fine for years, there are specific factors that can affect how long your lawn mower battery lasts.
Here are the main factors influencing the lifespan of a lawn mower’s battery.
Extreme temperatures affect how long a lawn mower battery can last. If you leave the battery in your mower over the cold winter months, then the battery may freeze and discharge.
On the other hand, lawn mower batteries also shouldn’t be left out in direct sunlight or extremely hot temperatures.
Hot temperatures reduce the battery’s capacity for holding a charge which affects the product’s lifespan.
It’s best to store your lawn mower battery at a moderate temperature to ensure that it lasts for as long as possible.
How often you charge your lawn mower battery can also affect how long it lasts. You can easily overcharge a lawn mower batter which means the charging capacity reduces over time.
But overcharging your battery isn’t just bad for its working capacity, it can also increase the battery’s temperature leading to fire and, in the worst case, to an explosion.
This being said, you should also never undercharge your battery, such as leaving it uncharged in your lawn mower over time.
Generally, it’s best to store your battery at room temperature and regularly charge it, even when you don’t use the battery.
Maintenance And Storage
Another big factor that affects how long your
As most people don’t use their mowers all year round, the battery of the lawn mower should be stored outside of the lawn mower at the right temperature.
You should also ensure that your lawn mower as well as the battery is regularly cleaned. Moisture and dirt can lead to rust and corrosion which affect the batter’s lifespan long term.
How To Extend The Lifespan Of Your Lawn Mower Battery
There are a number of different things you can do to extend the life of your mower battery.
Buy A Quality Lawn Mower Battery
Cheap battery materials quickly degrade the battery which means that it doesn’t last as long as the average battery lifespan.
That’s why it’s important that you invest in a good quality battery that ensures a longer lifespan of your product.
Follow The Mower’s Instruction Manual
Most lawnmowers and mower batteries come with an instruction manual that gives advice on how to look after your mower and the battery.
Use A Good Quality Charger
In order to extend the life of your lawn mower battery, you will need a good quality smart charger.
These chargers ensure you don’t overcharge your battery as they stop charging automatically.
Only Use A Fully Charged Battery
While a battery still works in your lawn mower when it’s not fully charged, it’s not good for the battery itself.
Lawnmower manufacturers recommend using only batteries that are fully charged.
Avoid Mulching Blades
Most lawnmowers have mulching blades that help to bag the grass clippings. However, these blades use a lot of power which affects your battery.
Mulching blades also use power when they are not in use. That’s why try to avoid using the mulching blades of your mower for a better battery life.
