Things you should know before buying a lawn mower:

Over the years, battery technology has developed to such an extent that even lawn mower engines can run without interruption over long periods, up to 2 hours for some models! Just a few years ago, battery lawn mowers would struggle running for 30 minutes straight, let alone offering the same power their diesel counterparts offer.

Newer model electric mowers with lithium-ion battery, however, are environmentally friendly, quiet, and, unlike the petrol mowers, odorless, but also offer you the freedom of cordless design.

Battery mowers for small lawns:

Light, agile, easy to use, and smart!

Once fully charged, you can easily mow small lawns or front gardens with a battery mower for up to 2 hours!. Although they don't offer as much power as gas mowers or cable mowers, their lightweight and compact size make them very light, maneuverable, and a joy to use. Even multiple lanes can be mowed effortlessly in one go without getting backaches. They also take up very little space in the tool cabinet or garage.

Also, lithium-ion batteries have become a lot stronger, and they don't have memory effects other types of cells suffer from, which causes the battery voltage to drop over time. This usually happens with different types of batteries when you repeatedly interrupt their charging and discharging cycles. Lithium-ion batteries, therefore, have a long service life and also offer weight advantages, as they weigh up to 60% less than comparable lead-acid batteries.

The only drawback is that battery charging times are usually somewhat longer, making battery mowers more suitable for occasional use. To find the right lawnmower, it is worth taking a look at our battery mower 2020 comparison tool we have created for you above.

How much does a battery lawn mower cost?

For a good battery mower you should budget at least 200 - 500 dollars. When buying a battery mower, make sure that at least one battery and a charger are included in the box. Otherwise, they have to be purchased separately.

How long do battery lawn mowers last?

Depending on the model, aH, and the number of batteries that come with your mower, you could expect it to last anywhere between 30 minutes to 2 hours.

Are battery lawn mowers any good?

If you can't live without the freedom a gas lawn mower offer, but at the same time you'd prefer your mower to be much lighter and quiter, then buying an excellent cordless battery lawn mower could be your best option. It combines the advantages of both types of lawn mower.

However, whether you should buy a battery lawn mower or not, is very much depends on the size of your lawn. Since these devices are powered by lithium-ion batteries, mowing range you get per session is somewhat limited. In average, a cordless electric lawn mower will give you a mowing time of 30-40 minutes, some models up to 2 hours with multiple batteries. Snapper XD 82V battery lawn mower for example, includes 2 lithium-ion batteries and a fast charger, which allows you to mow your lawn up to 1.3 hours by simply swapping the batteries. For most other models, you need to purchase second battery separately.

Life expectancy and replacement batteries

When purchasing cordless mowers, you should also make sure that original replacement batteries are available. With good care, Li-ion batteries can be used for three or more consecutive years before their performance gradually deteriorates. With well-known manufacturers such as WORX, which also offer many other cordless garden devices, battery can be swapped between the devices and thus be used more effectively.
