How To Maintain Li-ion Battery Lawn Mowers


Your garden or lawn needs to be taken care of properly to avoid the overgrowth of grasses that will make it look ugly and untidy. What other way can you keep your garden or lawn in shape other than making use of a lawn mower to level the grass and make them look attractive. The importance of these lawn mowers cannot be overemphasized especially during summer when our grasses get used more than during the rest of the year so it’s important to look after it, and these lawn mowers can help you get your lawns ready for the summer with ease.

There are lawn mowers that run on petrol while others are battery powered. One of the major setbacks that come with using petrol engines is the number of components. From spark plugs and carburetors to changing of oil yearly, there can be a lot to maintain. With a battery powered mower there are fewer moving parts it is easier to maintain and lesser time is spent on maintaining it.
One other setback that comes with using a petrol lawnmower is the noise. The sound of a lawnmower from a neighboring house in the morning can be a very annoying sound. As the battery mower runs off an electric motor it’s much quieter when being operated, that would be much less annoying to your sleeping neighbors.

Another benefit is that most batteries powered mowers are lightweight and easy to handle. Another great advantage of cordless battery lawnmowers is that will give you the opportunity to move further without you getting worried about the cable getting tangled in bushes or the fear of mowing over the line.

Types of battery

Battery selection must be put into consideration because when it comes to lawnmowers the type of battery you use goes a long way. The battle of batteries will be between the Nickel-Cadmium (NiCd) batteries and the (Lithium-Ion) Li-Ion batteries. (For the purpose of this article we will be focusing on the Li-Ion batteries) both lawnmowers have pros and cons as it mostly comes down to longevity vs power. NiCd batteries can handle strenuous conditions without failing and they are the cheaper option.

The main setback of these batteries, however, is that they need to be fully discharged before recharging otherwise they can lose their power density thereby causing then not to run as long as they used to when they were purchased new. The power output also gradually decreases as the battery runs out, which can cause a decline in the performance of your machine. Li-Ion batteries, on the other hand, can have a very high power density (around double the power of NiCd) and a higher power output which means that it provides a better cut your mower.
These batteries also need very little or no maintenance, which is helpful if you are going to have a mower for a long period of time. Their lithium-Ion batteries are very quick to charge and provide about 20 and 40 minutes of hassle-free mowing, which is plenty long enough for the average garden. The main problem with the Li-Ion batteries is they can deteriorate in charge capacity after a few years.


Almost all cordless hand tools nowadays use Li-ion batteries. If taken care of properly, they can very durable and convenient to use. The general performance of a battery is measured in terms of capacity, a leading health indicator. Internal resistance and self-discharge also play roles, but these are less important in predicting the end of battery life with Li-ion. The ionic movement of the positive and negative electrodes serves as the base of operations for the lithium-ion battery. In other words, such a mechanism should work forever, but cycling, elevated temperature and aging decrease the performance over time. The following are different ways you can maintain your Li-ion battery lean mowers to make them last longer:

There’s is nothing worse than having the batteries in your new mower last for just a few months because they were not properly maintained from the beginning. So when you get a brand new mower, always make sure that the batteries are fully charged. Failure to ensure that they are fully charged the first time can affect its performance because if you just go out and mow your lawn right away, they might not last as long as they should.
After each day’s use, you should recharge your batteries. Leaving the battery for days before recharging is not advisable. The charger that comes with your electric riding mower is designed to charge up the battery, bring the battery to its peak charge and then maintain that charge. Endeavor to charge after each day use as failure to that will greatly shorten the battery life.

If possible avoid draining your batteries over 80 percent. Full usage till it gets to 0% will destroy the batteries quickly. If this is done often the batteries may only last a year.
Avoid using a charger other than the one that came with your electric riding mower. If your charger develops a fault or spoils purchase the exact replacement. Never try to replace the charger with a similar charger
Note that your electric riding mower uses an automatic battery charger that constantly monitors the charging process, and stops the charging process once the batteries are fully recharged. For this reason, only a battery charger that is being recommended by the manufacturer of your mower should be used. Cycling alone does not cover it Environmental conditions also govern the longevity of lithium-ion batteries.
The worst case scenario is keeping a fully charged battery at high temperatures. Battery packs do not die suddenly, but the duration gradually shortens as the capacity fades. I recommended that batteries be stored in a cool, dry place, but not below 32F, and charged every one to two weeks, ensuring that they remain fully charged so as to prevent deterioration. They are very reliable.
