How Long Does a Lawn Mower Battery Last – 6 Different Ways to Increase Life

Are you looking to purchase a lawnmower to level grass but facing confusion due to its battery lifespan? If it’s a yes, you can easily eliminate this dilemma by gaining required knowledge about batteries of lawnmowers. Although a battery replacement option is available, individuals usually do not prefer it because of high cost. Due to this reason, everyone is most likely to buy a lawnmower whose battery can last for a longer period and provide satisfying results. Here is detailed information about how long do lawn mower batteries last, different types of batteries available, and essential tips to increase their lifespan.

Types of Lawn Mower Batteries

The battery type has a crucial role in affecting the life of a lawnmower battery. There are two categories of batteries used in lawnmowers these days: Lithium-ion battery and Lead-acid battery.

Lithium-Ion Batteries

Lithium-ion battery is a modern age concept in lawnmower batteries. The principle behind its working involves transfer of charges from positive electrodes to negative ones while charging and gets reversed while the battery is in use. It is found that the life of a lithium-ion battery lasts up to 5 years, but it can reduce to 3 years if the battery is not maintained properly. However, it is better to analyze the battery’s life in terms of charging cycles. If use of lawnmower exceeds average use, then standard 500 charging cycles will be accomplished in less than three years.

The life of a lithium-ion battery also depends on the material used to make the battery. It is observed that premium quality material furnishes benefits like extended battery life, quick charging, and enhanced energy storage. Lithium-Ion batteries typically generate four volts per cell. But this average limit exceeds as a lawnmower can use around 72 volts for each cell or even higher power.

Lead Acid Batteries

Lead-acid battery, one of earliest forms of battery used in lawnmowers. It is not broadly utilized because it is unable to reach maximum capacity after getting completely discharged. The lifespan of lead-acid batteries is around 1 to 3 years or 300 charging cycles. These batteries utilized when temperature stands below 32 Fahrenheit or at this level. They can provide more impressive results than lithium-ion batteries. Further, lead-acid batteries produce 2 volts for each cell.

How Long Do Lawn Mower Batteries Last?

There is no way to predict the exact lifespan of a lawnmower battery. In some situations, the battery can work perfectly for up to 8 years, whereas in others, its life can end within a year. On average, a lawnmower battery lasts for around 3 to 5 years. However, the battery’s lifespan depends on the type of battery, its charge holding limit, and your usage patterns. Moreover, charging holding potential diminishes with time. An interesting fact with lead-acid batteries is that their life can be extended to 12 years if the user ensures routine checking and proper maintenance.

Nowadays, several lawn mowers come with voltage regulators to perform the role of a functional charging system and help in improving battery life. However, this aspect also affects performance and life of a fully-charged battery. Under normal circumstances, a lawnmower battery can work for an hour before it needs a recharge. But it can increase a little bit with alternators and regulators. But the operating time of a charged battery depends on multiple factors. Further, the charging time of lithium ion batteries installed in lawn mowers is approx. 100 minutes.

Tips to Increase Battery Life of a Lawn Mower

Managing a lawnmower battery is essential to achieve desired results without incurring any extra cost. If not maintained properly, its life can end within a few years. So, here are effective and simple tips that you can use to enhance your lawnmower’s battery life and performance.

1. Use Fully Recharged Lawnmower

If you use your lawnmower before charging it to maximum level, then it can become a factor that will reduce its battery’s life. Although it will not lead to problems in the mechanical components of the lawnmower, it can develop troubles with the battery. Therefore, it is always recommended that you start using your lawnmower after completely recharging the battery.

2. Raise Height of the Mower

You can raise the mower’s height while dealing with taller grasses. It will reduce moisture content in equipment. The absence of high moisture levels doesn’t put immense force on the motor, and drainage of the battery will be reduced. It diminishes the need to recharge again and again.

3. Avoid Using Self-Propelled Feature

For reducing load on batteries, it is better to prevent usage of self-propelled features. This feature consumes more power and increases existing load on batteries. You can use it occasionally, but frequent application of this feature must be avoided.

4. Purchase Premium Quality Batteries and Charger

It is a step that you can take before using a lawnmower. Buying duplicate batteries can decrease a product’s life to a great extent. Apart from batteries, you have to buy a quality charger. An old charger can increase risk of damage to batteries and often leads to overcharging. New-age smart chargers automatically stop charging when the battery gets fully charged. This technique extends the average life of lawnmower batteries.

5. Follow Instructions from Guide Manual

This can be one of most effective solutions in extending life of batteries. Reading every instruction from the manual and then implementing it while working will be beneficial for the lawn mower and its batteries.

6. Don’t Use a Lawnmower in the Early Morning

The moisture aspect affects the battery’s performance and plays a huge role in diminishing the actual lifespan of the battery. The grass remains wet in the early morning, and water particles remain present at top. Therefore, it is suggested that you wait for grass to dry out to retain the actual performance of equipment. A lawn mower can work on wet grass, but you have to put in extra effort, and the device also consumes extra energy. Due to this reason, it is essential to protect the energy source of the mower, i.e., the battery.

Does a Gas Lawn Mower Last Longer than an Electric Mower?

The run time and battery life of gas lawn mowers and electronic mowers differ, and it is crucial to understand them to obtain better results in the long run. For gas mowers, it gets tough to analyze the runtime they will generate with a tank full of gas. The actual running time depends on the speed at which you operate the mower and grass density you wish to cut. However, it has been found that the runtime of a gas lawnmower exceeds that of an electric mower when provided with similar energy.

Usually push or electric lawn mower battery life is for two hours on a single charge. On other hand, if you prefer a plug-in electric mower, there is no issue with runtime as it keeps working continuously. In simple words, as long as you provide the mower with electricity, it will continue to cut the grass of your lawn.

Gas lawn mowers depend entirely on the capacity of their fuel tanks. Usually, a gas-powered mower has a gas tank with a 1-gallon capacity. You can refill the tank whenever you want. First, however, it is necessary to add oil to the tank. It facilitates smooth working of engine parts and contributes to efficient performance of the motor.

FAQs

1. What is riding lawn mower battery life?

The average life of a riding lawn mower is 4 years.

2. What type of battery is a lawn mower battery?

Generally, most of the lawn mowers work with 12V batteries and small ones use 6V batteries. Refer the above section regarding types of batteries for detailed info.

Conclusion

Lawnmower batteries’ lifespan depends on usage requirements and type of batteries installed in the lawn mower. Normally, lawnmowers use lithium-ion batteries, and their health is affected by charging cycles. However, the right implementation of charging cycle, reasonable usage, and proper storage contribute to increased lifespan of batteries beyond average lifetime. Moreover, following manual instructions and applying some tips can furnish optimum results in your lawn for a longer period.
