How Many Amps Does An Electric Lawn Mower Use?

The amp rating of the mower is a crucial to determining which gauge or wire thickness is ideal for that model; the amp rating is listed in the owner’s manual or on a sticker or plate on the mower. Mowers that run on electricity typically use 6 to 12 amps. The lower the gauge number, the greater power the cord can withstand when picking a cord based on gauge. Which gauge is best for the mower is also determined by the maximum distance from the outlet to the mower. A 16-gauge outdoor extension cord, for example, will most likely suffice for a cord up to 100 feet long if your mower is rated under 10 amps. A 12-gauge wire is a preferable choice for a lengthy extension cord for a mower rated at 10 to 15 amps, as it is built to handle the higher load and long distance. A low-number-gauge cord designed for outdoor use and harsh conditions is a better choice than a cord that isn’t strong enough for your mower. The mower may overheat if the cord is insufficient.

Is a 13-amp lawnmower a wise choice?

For general mowing, 13 amps is sufficient. Because the mower has a mulching plug, you won’t have to bag the clippings if you keep up with the mowing. This is a good, basic mower for modest homes and yards. It’s wonderful not to have to worry about gas, oil changes, or the noise that comes with a gas mower!

What is the energy consumption of an electric lawnmower?

What Is the Power Consumption of an Electric Lawn Mower? Electric mowers use between 600 and 1800 watts of power each hour.

What is the amp hour capacity of a lawn mower battery?

Most 12-volt lawn tractor batteries are less powerful than the Universal Power Group battery. This battery produces 35 amp hours instead than the usual 5 to 18 amp hours.

This battery’s absorbent glass mat technology, in addition to its high output, reduces the possibility of spillage if the battery overheats or cracks, while also allowing the battery to be fitted in any position.

What is the voltage need for an electric lawn mower?

We’ve covered everything you need to know about battery-powered lawn mowers in this shopping guide, including what to look for in terms of runtime, power, blade speed, and more. To find the best model, consider the following factors.


The performance of a battery-powered lawn mower is represented by power. Volts are the units of measurement. Lawn mowers that run on batteries have a voltage range of 36 to 120 volts.

Underpowered models may cause the blade to slow down while cutting the grass, especially if the grass is tough or thick.

Lawnmowers with a greater voltage (above 70 volts) may readily generate the additional power needed for self-propelled wheels. As a result, more torque is available to cut through dense grass with ease. Even though they improve performance and are suitable for medium-large yards, they are costly and come with trade-offs.

A 70-volt battery, for example, is heavier than a 40-volt battery. As a result, more power is required to propel it ahead, reducing runtime. As a result, the mower becomes difficult to maneuver and operate.

Low-voltage mowers (3665 volts) are lighter, easier to maneuver around obstacles (such as shrubs or trees), more cheap, and better suited to small yards.

Battery Runtime:

Most battery-powered lawn mowers have a run time of 30 to 60 minutes. The runtime (amp-hour/Ah) of a battery indicates how long a mower can operate at one time. As a result, the larger a battery’s Ah, the longer it will survive before needing to be recharged. In addition, the size of your yard will help you determine the ideal battery-powered lawnmower runtime.

If you have a smaller lawn, you can easily mow the entire lawn without stopping to recharge the battery in the middle, but if you have a larger lawn, you will need to stop to recharge or replace the battery (if you have an extra battery).

Note: When mowing a yard with thick or tall grass, obstacles and slopes diminish the runtime of the mower, causing it to slow down.

Cutting Width:

How broad a lawnmower can cut in a single pass is determined by the cutting width or deck size. In general, previous cordless mower deck widths are narrower than gas mower deck widths (about 16 to 18 inches), but newer models typically have cutting widths of 20 to 22 inches.

The larger the mower’s deck, the fewer passes it takes to mow your grass. A mower with a narrow deck size is great for tiny lawns since it can fit into smaller spots, whereas a larger yard should have a few extra inches of breadth to save time and effort.

Smaller mowers with a cutting width of less than 20 inches are suitable for lawns of less than 1/4 acre, while larger mowers with a deck width of more than 20 inches are suitable for lawns of more than 1/4 acre. In the ordinary battery-operated electric mowers, most brands give 20 to 21 inches, which is plenty.

Blade Speed:

To determine the performance of your lawn mower, you must consider the blade speed. The speed of the blade is measured in rounds per minute (RPM). When mowing the grass in your yard, a blade with a greater speed will provide better cutting performance and consequently clean cuts.

Blade speeds vary depending on the cordless mower. Options with blade speeds of 1500 RPM or 2000 RPM are readily available; choose the one with the higher blade speed. Most mowers have a variable speed trigger that allows you to simply modify the blade speed to meet your needs.


The amp-hour reading tells you how much runtime the battery has. In layman’s terms, it shows you how long the lawn mower can run in a single pass. Lawn mowers have two different battery capacities: 2.0 Ah and 4.0 Ah. The higher the rating, the longer the battery life.

Lawn mowers can cut grass continuously for 30 minutes to an hour on average. They can mow 5,000 to 10,000 square feet in this period before you have to recharge.

You don’t require a long runtime for small to medium-sized lawns. If you have a larger lawn, though, you should invest in a model with a longer duration.

Another fantastic benefit of battery-powered lawn mowers is that you can have many backup batteries in your toolbox. When the battery runs out, simply replace it with a new one and continue working as usual.

Adjustable Cutting Height:

You can cut grass at varying lengths with a lawnmower with an adjustable deck height. We know that different varieties of grass require varied heights of cutting to avoid harming the plants or the earth. While gas-powered mowers require individual height adjustments at each wheel, these cordless electric mowers do not.

As a result, a mower with an adjustment system such as a lever that allows you to simply lift the deck on all four wheels at the same time will be your best and most convenient alternative.

The majority of these cordless electric mowers have different height adjustment options for their decks, ranging from 1.5 to 4 inches. All you have to do now is choose the appropriate height for cutting the lawn to your chosen length.

Battery Type:

The majority of these battery-powered lawnmowers use lithium or lead-acid batteries. Each type has its own set of advantages and disadvantages.

  • Lithium batteries are smaller, lighter, charge faster (60 minutes), cost less, last longer, and are more efficient. Before recharging this battery, it must be totally discharged. As a result, it’s ideal for mowing larger yards because it allows you to complete the job quickly.
  • Heavy Lead Acid Batteries – These batteries are bulky and take longer to recharge (12 hours). It must be replaced frequently and recharged once it has been used for 50 to 80 percent of its capacity. However, it works perfectly for cutting your lawn.

Is an electric mower less expensive than a gas mower?

Because they don’t have a gas engine or batteries, corded electric mowers are the most affordable, costing between $150 and $250. Battery-powered lawn mowers range in price from $275 to $800 or more, depending on features like self-propulsion. (To compare, here’s a list of the best electric mowers on the market.) Mowers that run on gas are among the most expensive: Models start at roughly $350, but they can go up to $850 or more for a self-propelled gas mower in the upper range.

How long does the battery on an electric mower last?

The battery in an electric mower can last up to 5 years, while the mower itself can last up to 10 years. Your electric mower battery should last up to an hour before needing to be recharged, depending on the device you buy.

When it comes to cost and efficiency, using an electric mower might be beneficial. Electric mowers are also easier to clean, maintain, and run. Their long-lasting batteries can be just what you’re looking for to save time and money. I’ve broken down how long electric lawn mowers last and why having one is so vital when it comes to mowing your grass.

Is it true that electric mowers save money?

You have two choices when it comes to replacing your gas push mower with an electric push mower: a corded electric mower or a cordless electric mower.

Corded electric mowers

A corded electric mower that plugs into an extension cord is available. If you have a tiny yard and an extension cord within reach, you might be able to use this. In terms of initial cost, corded electric mowers are the lowest option, and you never have to worry about replacing batteries.

Cordless electric mowers

You can acquire a cordless electric mower if you have a larger yard or don’t want to deal with an extension cable. Rechargeable electric batteries, usually lithium batteries, are used in these. If you have a large yard, you may require more than one battery to mow it all at once. Rechargeable batteries have a five-year life expectancy on average.

Initial cost

There are many various types of push mowers available, each with its own set of features and capabilities. A corded electric mower can be found for around the same price or even less than some gas push mowers, depending on the type. A cordless electric model, on the other hand, can cost $100 or more than a comparable gas type. I’ve chosen examples of machines with similar capabilities that might mow a typical medium-sized yard for comparison.

Operating costs

The most expensive part of operating a push mower is fuel, which costs roughly $2.30 per gallon or around 11 cents per kilowatt hour to run a corded electric mower or charge the battery. This equates to a fuel cost of around:

Assume you mow your half-acre lawn once a week for four months, or 16 times a year. The annual cost is calculated as follows:

Let’s pretend you’ve had your mower for ten years. The overall cost of fuel during a ten-year period is:

Maintenance costs

Batteries, of course, do not last indefinitely. Assume you’ll need to replace your rechargeable battery after five years, or once over the mower’s 10-year lifespan, at a cost of $75.

Regular maintenance is required for a gas mower, which is not required for an electric mower. Let’s say you change the oil once a year and the spark plug and air filter every other year, for a total of $15 in annual maintenance.

All of the lawn mower blades will need to be sharpened or changed on a regular basis, and let’s say it costs $20 every other year, or $10 per year on average.

year total cost of ownership

Here’s an estimate of a push mower’s total cost of ownership over ten years.

$235 for the initial purchase, $240 for gas, $150 for engine maintenance, and $100 for blade sharpening/replacement equals $725.

$179 for the original purchase plus $80 for power and $100 for blade sharpening/replacement equals $359.

$315 for the original purchase + $16 for energy + $75 for a new battery + $100 for blade sharpening/replacement = $506

You will save a substantial amount of money on gasoline and routine maintenance each year if you use a corded electric push mower or a cordless electric push mower. For cordless models, there is a recurring need to replace batteries as they wear out, but the savings on gasoline and engine maintenance outweigh this cost throughout the mower’s lifetime.

When compared to a gas-powered push mower, a cordless electric push mower can save you money depending on the type you choose and the size of your yard. And, when compared to the other two types of mowers, a corded electric push mower will save you money.

What is the amp rating of a 12 volt lawn mower battery?

You may also see an electric cordless mower with a number of amps shown, but this is not the same.

Because these mowers do not have gas engines, this does not refer to cold cranking amps. Rather, this is the amount of current sent by the battery to the engine.

If you’re asking this question, the answer is straightforward. Most modern battery-powered lawn mowers feature 12amp engines, which means the engine is constantly supplied with 12 amps of current. For most home users, this is sufficient.

In a lawn mower, how long will a 2.5 Ah battery last?

The 2.5Ah ARC LithiumTM battery is small, yet it packs a punch. It can mow up to 400 square meters of lawn, trim hedges for up to 75 minutes, chainsaw up to 130 times, or line trim for up to 70 minutes (dependant on tool, percentage of charge and conditions of use).

Is the power of electric mowers sufficient?

Electric mowers are less expensive than gas mowers and can usually handle most lawns. If you have long, thick grass or try to cut it when it’s wet, a low-powered electric mower will be overworked, so choose your mower carefully to fit your demands.

Top tip If you’re faced with an overgrown patch of pasture that hasn’t seen a lawn mower in years, consider borrowing a gas-powered mower for the first pass (check local tool libraries or ask friends and family), then saving money and the environment by maintaining with a more environmentally friendly electric mower.

Electric mowers are also considerably easier to maintain and store than gas mowers. The only other requirement to keep an electric mower in good shape is to replace the brushes on the motor. Aside from basic inspections (such as making sure the wiring is in good condition) and a little cleaning, the only other requirement to keep an electric mower in good shape is to replace the brushes on the motor.

You should clean the cutting deck of both gas and electric mowers after each usage before storing them. This entails using a stiff brush and water to remove fine lawn cuttings caught between the blades. If your faucet has a hose attachment, all you have to do is plug in your hose and turn on the water.

Check the general condition of the mower at least once a year for all mowers, noting the state of the fuel pipes, electrical wires, nuts, bolts, paintwork, and other components. Remove any dirt or rust that has accumulated, then re-paint or apply a rust inhibitor to any exposed metal. Grease bearings, levers, and shafts once a year, and tighten any nuts and bolts that need to be tightened.
