Battery-powered lawn mowers are making a big push in the market. When buying cordless lawnmowers, it is significantly essential to consider the right voltage. The most common battery voltage for mowers is 40v and 80v. But which one should you go for, between 40v vs. 80v batteries? Before selecting, you need to know the difference.

The key difference between 40v and 80v mowers is their power and efficiency. Undoubtedly, 80v mowers come with a higher voltage, more power, and more efficiency than 40v.

Below, I will compare 40 volt vs. 80 volt lawn mower, helping you make a precise decision.

40v vs. 80v Lawn Mower – What is the Main Difference?

This section focuses on the prime differences of 40v vs. 80v lawn mower. Read carefully as the buying decision depends on the below factors significantly.

Voltage

Both 40v and 80v mowers deliver good performance, but when the question comes which provides overall better performance, the vote will go to the 80v.

The overall working of a lawn mower depends on the electric force. Always remember that more electric force means better performance. In this case, 80v offers more electric force, which makes it superior to 40v mowers.

Happily, smart cut technology is one of the best features of both 40v and 80v mowers. This feature provides more power, helping you mow the grass on rugged and uneven terrains. Impressively, this is a significant technology suitable for the customers as it can ensure that the lawn surface will be even every time after mowing. Due to these characteristics, 40v and 80v mowers can help you get the mowing task done conveniently.

Therefore, 80v wins the battle for its better electric force distribution.

Run time

Run time is one of the essential features of every mower, and it is no exception for a battery-operated lawn mower.

40v mowers come with a run time of 45 minutes. On the other hand, 80v mowers run for 60 minutes. This means that run time is one of the key differences between 80v and 40v mowers.

More run time is better for consumers, allowing you to mow large lawn areas before the next recharge. You will never have to think about swapping or charging the drained battery during the mowing process when you have an 80v mower. Moreover, an 80v mower can easily cut grasses on a large lawn.

But a 40v mower is good for small or medium-sized lawns. If you buy it for a large lawn, you will need to put it for charging as the battery drains faster than 80v.

In summary, the 80v battery is the winner regarding run time because of the better battery capacity.

Size & Weight

You must be wondering that the size and weight of an 80v mower will be larger and heavier. In reality, there is no significant difference between 80v and 40v mowers in size and weight.

Both mower types have decent size and weight, allowing you to move the lawn mowers easily around the lawn. Also, stability and required power are confirmed in both mowers.

So, it is a tie between the two lawn mowers.

Charging Time

The charging time of a lawn mower incredibly depends on its battery voltage.

The 80v mower will take only 30 minutes to get fully charged. Meanwhile, 2 hours is the charging time of a 40v mower.

The fast charging feature helps you reduce downtime. Also, you can get back to work after the battery is completely drained.

However, charge the lawn mower slowly for all voltages to get efficient and safe performance. This way, you can avoid overheating and overcharging to improve the longevity of the lawn mower battery.

Source of Charge

The good news is that both 40v and 80v mowers can be charged with the help of a wide range of charging sources.

You can plug both mowers into your nearest power outlet for charging purposes. Also, they can be charged with a generator. However, keep in mind that putting the generator in economy mode when charging takes assistance from a generator.

In this case, both are the winners.

Noise Level

The decibel level of 40v lawn mowers is less than 80v mowers.

Due to their less noisy nature, 40v mowers have a minimal environmental impact. Since they are not louder, your neighbor will not make a complaint when mowing. Additionally, you can concentrate on the mowing task with 40v mowers, improving your productivity.

Power Level

The 80v mowers are 2X more powerful than the 40v mowers. So, they work with more power and force, letting you complete big jobs in less time. There are a few tasks that an 80v mower can do effortlessly that the 40v mowers cannot manage.

Holding a Charge

In the case of holding a charge, both mowers are fairly well.

The 40v mower is in charge every 2.5 months when not in use. In comparison, 80v mowers must be charged only every 3.5 – 4 months when not used. It means the 80v mowers hold their charge for many days.

Warranty

Almost all the manufacturers provide at least 4 years of warranty for 40v and 80 mowers.

The warranty comes in handy if the batteries become less powerful. In such situations, you can claim for replacement with the durability clause.

Therefore, both 40v and 80v win the race here.

Pricing

Price is always a crucial factor in deciding which lawn mower to buy.

When comparing the price, 40v mowers are cheaper than 80v mowers. With enhanced run time, 80v mowers deliver better performance in comparison to 40v. For the 80v mowers overall improved performance and features, they are highly-priced.
