How long does the battery in a lawn mower last?
You just bought a great lawnmower and can’t wait to even out your grass. However, most people don’t know how long the batteries last, which can be confusing. This is smart because it can be hard and expensive to change the battery. You also want to know how long the lawnmower will run after the battery has been charged all the way up. Don’t worry; this article will explain everything about battery life and suggest ways to make it last longer.
How long does the battery in a lawn mower last?
Most lawnmower batteries last between 3 and 5 years, but they can stop working after 1 year or last up to 8 years. This depends on how well the battery can hold a charge, which gets worse over time. How long a battery lasts depends on the type of battery and how it is used.
Different kinds of batteries
Lithium-Ion batteries and Lead Acid batteries are the two types of batteries that are used today.
Modern batteries use lithium-ion batteries. When the battery needs to be recharged, charges are transferred from the positive to the negative electrode, and then the process is reversed when the battery is being drained. The typical lithium-ion battery has a life expectancy of three to five years or 500 recharges. When someone uses their mover more frequently than the average person, the 500 charging cycles are accomplished in less than three years.
The quality of the lithium-ion battery’s material affects the battery’s features, such as fast charging, extended battery life, and increased energy storage capacity. Lawnmowers, which can utilize up to 72 volts per cell, can also use lithium-Ion batteries, which provide an average of 4 volts per cell.
● Lead Acid
Despite being one of the oldest forms of batteries, lead-acid batteries do not have the ability to return to full capacity once they have been depleted. Lead-acid batteries have a useful life of one to three years, or 200 to 300 recharges. When temperatures drop below 32 degrees Fahrenheit, Lithium-Ion batteries outperform lead-acid batteries. Each cell in a lead acid battery delivers 2 volts.
When the lawnmower’s battery is fully charged, it may run for an hour.
Powered by batteries, cordless electric lawnmowers can be taken anywhere. What many people are curious about is how long their fully charged lawnmowers can go before they need to be recharged. There has been an increase in the amount of time that electric lawnmowers can run before they need to be recharged. However, the length of time a lawnmower runs varies on a variety of factors, but in normal circumstances, it should run for around an hour. You’ll need to recharge your lawnmower’s Lithium Ion batteries after using it for an hour or half an acre (depending on your pace). A full charge takes 100 minutes.
● Battery management
Several changes and developments have been made to improve the lithium-ion battery’s performance in electric lawnmowers. Lawnmowers with brushless motors have longer battery lives since a motor without a brush only exerts force on batteries for a limited amount of time.
It’s like you’re raking through a field of tall weeds, and because of the tall weeds, the motor will have to work harder. There will be less force on the motor when the dense grass is removed, which will result in a reduction in power consumption when the brushless motor is used. Brushless motors employ a good power management approach, however brushed motors don’t have it. The battery’s lifespan will be improved, and the time it takes the lawnmower to complete the 500 charging cycles will rise as a result.
It’s also critical to cease using a lawnmower as soon as you see the power is waning, which indicates that the batteries are going low. You don’t need to get into the nitty-gritty, but utilizing batteries at a lower voltage will always have a negative impact on their lifespan.
● Battery care in winters
Batteries react differently depending on the temperature. It is imperative that you give careful consideration to the location in which you store your lawnmower, particularly if it has a battery that can be removed and you intend to store it away for the winter. It is recommended that the batteries be removed from the lawnmower and that it be kept at room temperature if it is going to be stored in the garage. The life of batteries can be severely shortened by exposure to cold temperatures, which can even cause them to completely stop functioning. Therefore, if you want them to be unaffected by the chilly weather, you have to keep them inside the store where they are kept.
You should also avoid putting your batteries in an area with an abnormally high quantity of dampness. The lifespan of the battery will be shortened as a result of its absorption of moisture.
● How charging cycle will affect battery life?
As we’ve seen with lead-acid batteries, once the battery is used up, it won’t go back to its full capacity if it’s used up to about 70% of its capacity. It will never go back to 100% because the price will only go up to about 70%.
Lithium-Ion batteries are not like other types. Unlike lead-acid batteries, they can be charged to their full capacity even after being half full and then empty.
Lithium-ion batteries depend on the number of times they are charged, because they can only be charged 500 times before they run out of power. The best thing to do with lithium-ion batteries is to charge them until they reach their full capacity and then use them until they run out of power. Do this cycle over and over. This will make the battery last longer.
When lithium-ion batteries get old, it takes longer to charge them and less time to drain them. If your lawnmower is taking longer to charge than usual, this means the batteries are getting old. If it used to take 90 minutes to fully charge your lawnmower, but now it takes 120 minutes, this is because the batteries are getting old. But this change won’t happen for 2–4 years.
How to get more use out of your lawnmower’s battery
1. Always use a lawnmower with fully charged batteries.
Using a lawnmower with batteries that aren’t fully charged won’t hurt the lawnmower’s mechanical parts, but it will definitely shorten the battery’s life. It’s best to use a lawnmower with fully charged batteries.
2. Raise the height of the mower.
The taller the grass, the less water will be in the lawnmower. Less water won’t put more force on the motor, so the batteries won’t drain any faster.
3. Keep moving your lawn mower.
More often you cut the grass, the less grass there will be when you do it again. Every week, cut twice.
4. Don’t mow the lawn too early in the morning.
Moisture is the problem again, since it rains at night. The grass is usually wet in the morning, so wait until it dries. The lawnmower will still work on wet grass, but it will have to work harder and use more energy. The battery is the source of energy, so we need to protect it.
5. Don’t use the part that makes it move on its own.
Using a feature that moves itself will use more energy. Again, if you use more energy, it will put more strain on your batteries. For better battery life, you shouldn’t use the self-propelled feature very often.
6. Don’t use a blade for mulching.
With the mulching blade, grass clippings are bagged and turned into mulch. But when they’re not in mulch mode, they use more power, which means they’ll use less power and last longer.
7. Follow the directions in the book.
Most people don’t read the solution manual, but you should read every instruction in the instruction manual about batteries. The manufacturer knows the most about his or her products, so read the manual and do what it says.
8. Get good batteries
It’s not a tip to increase battery life; it’s a requirement. No matter what you do, the battery life won’t get longer if you buy duplicate batteries.
9. Good battery charger
You will need a good smart charger if you want to charge a battery or store it for the winter. If you use an old battery charger, you could overcharge the battery and hurt it. These older chargers don’t automatically stop charging when the battery is full like smart chargers do today.
Every type of battery has its own pros and cons, and sometimes one type is better than another. On the other hand, a lithium-ion battery is usually used for the lawnmower. The health of lithium-ion batteries depends on how many times they are charged. If the charging cycle is done right, the battery will last longer. Also, storing the battery correctly and using the lawnmower correctly while following some instructions will definitely make the battery last longer than the average.
We think that in the future, lawnmowers will be more advanced and use less power while making batteries last longer.
