Everything has a lifespan, and everything wears and tears with time. Even a lawn mower battery.
The gardener’s primary concern is about how long a lawnmower battery can last. We think batteries run for years as they’re costly, but it has nothing to do with being costly. Rather, how much it has been used and for how long.
Like any other device, a battery dies too when it has supplied you with all the power that you need.
Meaning? You might need a new lawnmower batter. But how long does a lawn mower battery last?
The most probable reason you are here reading this article is that you meet the same concern. By the end, you must be cleared-headed of all the enigma you had before.
Though the option for battery replacement is available in the market, you should avoid it because it will be a churn to your bank account if you keep changing the battery.
It is why gardeners and people, in general, are most likely to buy a battery that has a long lifespan. Thus, it is advisable to stop changing the battery very frequently.
Instead, invest your time in a little extra research before buying the battery of lawnmowers and try to grab the best deal.
With progress, we will discuss with you the maximum life span of the best quality lawnmower, the different types present in the market, and what you should do from your side to ensure the long lifespan of lawnmowers.
Let’s go and have a look.
How Long Do Lawn Mower Batteries Last?
You cannot specifically find out the battery life of a lawnmower. Some batteries have recorded a perfect lifespan of eight years, and there are also a few batteries that last no longer than a year.
But on average, the total lifespan of the best kind of battery is around 3 to 5 years.
Nonetheless, the battery’s lifespan is influenced by the battery’s kind, charge-holding capacity, and usage habits. Also, over time, charging potential holding drops.
Lead-acid batteries have an intriguing fact: if the user provides regular maintenance and monitoring, their lifespan can be increased to 12 years.
In contemporary times, many lawnmowers have voltage regulators added to them to perform the role of a functional charging system and help improve battery life.
But other factors also intervene here. The voltage regulators affect a fully-charged battery’s performance, function, and life.
A typical lawnmower battery can operate for an hour before needing to be recharged. However, alternators and regulators could cause it to rise slightly.
A charged battery’s operational time depends on several variables.
Additionally, the lithium-ion batteries used in lawnmowers take about 100 minutes to charge fully.

Types of Lawnmower Battery Present in the Market
The kind of battery you use impacts the battery’s life span. However, two kinds of lawnmower batteries are present here, which are very prominent: Lithium-ion and Lead-acid batteries.
1. Lithium-Ion Battery
Lithium battery is a very new-of-a-kind concept introduced for lawnmower batteries. The idea behind how it works is that when the battery is being charged, charges are transferred from positive electrodes to negative ones, and during use, the process is reversed. A lithium-ion battery can last up to 5 years, but if it is not maintained correctly, it can only last three years.
But it is preferable to measure the battery’s life cycle in terms of its charging cycle. If you use the battery for more than its average lifespan, standard 500 charging cycles will most likely be accomplished in less than three years.
Another factor that affects the life span of the lithium battery cycle is the material that has gone into the making process.
It is very much tested and verified that the battery made of standard battery material gets you the leverage of extended battery life, quick and effective charging, and enhanced energy storage.
Typically, lithium-ion batteries output four volts per cell. However, a lawnmower can require up to 72 volts for each cell or even more; thus, this average limit is exceeded.

2. Lead-Acid Battery
One of the many lawn batteries introduced earlier was the lead acid battery. Lead-acid batteries were among the first to be used in lawnmowers. Due to its inability to attain its maximum capacity after being fully drained, it is rarely widely used.
Lead-acid batteries have a lifespan of roughly 300 charging cycles, or 1 to 3 years. These batteries are used when the temperature is this low or at this level. When compared to lithium-ion batteries, they can deliver more impressive results. Additionally, each cell in a lead-acid battery produces 2 volts.
Tips to Increase the Battery Life of a Lawn Mower
Here are some tips on how you can increase the battery life of your lawnmower and run it for a few more years.
1. Always use the Lawnmower When the Battery is Fully Charged
If you use the lawnmower without it being 100% charged, it might not affect the mechanical component of the mower, but it will for sure affect the battery life of the mower.
Therefore, we recommend you use the battery once it is fully charged.
2. Elevate the Height of the Mower
The higher the grass will be, the lesser the moisture consumption by the lawnmower. The lesser will be the moisture in the lawnmower; the lesser will be the extra force on the mower.
Thus, the battery life span will not be compromised if you elevate the height of the lawn mower.

3. Move Your Lawnmower Time and Again
The longer you cut the grass, the more constrained it will be when trimmed again. Cut the grass twice a week.
4. Avoid, If Possible, Using the Lawnmower Early in the Morning
Again here, the actor behind it is the moisture. Because in winter, there is due of night covering the grass early morning, the grass is moist in the early morning.
Though the lawnmower will still operate over wet grass, it will work harder and need more energy. The battery we need to maintain is the source of this energy. Thus there is a chance of endangering the life of the battery.
5. Do Not Use the Self-Propelled Feature
The energy needed to operate self-propelled features is very high. Again, higher energy demands will result in higher battery loads. For improved battery timing, the self-propelled feature shouldn’t be used frequently.
6. Use the Mulching Blade Rarely
With a mulching blade, you can mulch grass clippings. But, when you don’t use it in the mulching mode, it will extract much energy that affects the battery’s life span.
7. Follow the Instruction Manual
The majority of people throw the instruction manual comes with the battery. But, it is not advisable. One must give a straightforward read to this instruction chart.
Why? Because the manufacturer knows the most about the product. So read and follow the manual.
8. Buy a Quality Battery
It is not a suggestion, but a must, to extend battery life; if you get duplicate batteries, there is nothing you can do to extend battery life.
9. Purchase a Good Quality Charger
You will need the best smart charger for winter storage or battery charging. You run the danger of overcharging and harming the battery when using an old battery charger.
Compared to contemporary smart chargers, these outdated chargers don’t automatically cease charging when the battery is full.
FAQ’s
Yes, you can charge the lawn mower battery using the automobile charger if you need to. There is no harm in it.
The battery of the mower charge itself when the engine is working. So, the battery charges itself, provided the engine is working.
It is around 3 to 4 years.
While most riding lawnmowers use 12V batteries, some models, especially smaller ones, use 6V batteries.
You can use a multimeter to determine whether or not your lawnmower battery is dead. For this, connect the multimeter to a battery. You need to replace the battery if it reads less than 12 volts. The reading should be below or equal to 12 volts for a healthy battery.
Conclusion
Worried about – how long do lawn mower batteries last? Do not.
Every lawnmower battery has pros and cons; one can be good in one factor, and another can be best in another. But, the lawnmower’s standard battery is considered the lithium-ion battery.
Since the life span of the lithium-ion battery depends upon the charging cycle, thus with the proper implementation of the battery charging, you can very quickly help the battery sustain a long life.
Besides the proper charging, if you follow the instructions given by our end in the tips section, you will not have to worry about the battery life of the lawnmower and can focus entirely on maintaining the good health of your lawn.
