Lawn Care Made Easy: Understanding Battery-Powered Lawn Mowers
Battery-powered lawn mowers are a type of lawnmower that uses rechargeable batteries as their primary source of power. They offer an alternative to traditional gasoline-powered and corded electric mowers, and they have become increasingly popular due to their environmental benefits and ease of use. Here's an explanation of battery-powered lawn mowers:
Power Source, Runtime, and Charging
Battery-powered lawn mowers are equipped with one or more lithium-ion batteries that store electrical energy. These batteries are typically located on or near the mower's deck, providing power to an electric motor that drives the blades.
The runtime of a battery-powered mower depends on the mower's battery capacity and the size of the lawn. Smaller lawns may only require a single battery charge, while larger lawns might need multiple charges or a mower with a larger battery capacity.
Charging your lawn mower's batteries is simple. Most models come with a charger that you plug into a standard electrical outlet. Charging times can vary but are usually takes a few hours to charge the batteries fully.
Environmental Benefits
Battery-powered lawn mowers offer two major advantages:
- Zero Emissions: They produce no direct emissions of harmful gases like gasoline-powered mowers, making them more environmentally friendly.
- Reduced Noise: They are generally quieter than gas-powered mowers, which can help reduce noise pollution in your neighbourhood.
Convenience
Besides environmental benefits, these models are also:
- Cordless: Unlike corded electric mowers, battery-powered mowers are cordless, offering greater freedom of movement and eliminating the need to worry about extension cords and outlets.
- Easy Start: They typically start with the push of a button or the pull of a lever, without the need for priming or pulling a starter cord.
- Low Maintenance: Battery mowers require less maintenance compared to gas mowers, as there is no need for oil changes, spark plug replacements, or fuel storage.
Cutting Performance
Battery-powered mowers can provide good cutting performance, but the quality of the cut may depend on the blade design, cutting width, and the mower's overall build quality. Some models have features like mulching, bagging, or side discharge options.
Compared to its counterparts, battery mowers are a good choice for smaller lawns and eco-conscious users who value convenience and quieter operation. Gas mowers are suitable for larger lawns and heavy-duty cutting tasks.
Electric corded mowers can be a compromise between the two, offering consistent power without the emissions of gas mowers but with the limitation of cord length. The choice between them depends on lawn size, terrain, environmental concerns, and user preferences.
Weight and Maneuverability
Battery-powered mowers tend to be lighter than gas mowers, making them easier to push and maneuver. This is especially beneficial for users with smaller lawns or those who may have difficulty with heavier equipment.
Cost and Maintenance
Battery-powered lawn mowers can have a higher upfront cost compared to some gas-powered mowers, but they can save you money in the long run due to lower operating and maintenance costs.
While they require less maintenance than gas mowers, you will need to replace the batteries eventually. Lithium-ion batteries have a limited lifespan and will need replacement after a certain number of charge cycles.
When choosing a battery-powered lawn mower, consider factors like battery life, cutting deck size, terrain, and your lawn size to ensure you get the right mower for your needs. Regularly maintaining and properly storing your battery can extend its lifespan and ensure reliable performance.
Choosing a Battery for Your Mower
You can buy a wide range of 18V tools, ideally suited for various household tasks. These batteries are often interchangeable with your other devices; thus, it's a common practice for residential-grade battery-powered lawnmowers to employ a dual 18V battery setup, resulting in a 36V system. Nevertheless, we do not recommend these for commercial use in lawn care services.
Note, however, that higher voltage batteries have an advantage: the current drawn is less. To produce 1200 watts from a 36V battery would require 33.3 A compared to 14.6 A at 82V. Because most 36V systems use 2 x 18V batteries in series, that’s a current draw of 33.3 A for each battery. Drawing this level of current over a long period would cause excessive heating. So, generally speaking, the higher the battery voltage, the better.
Ah is simply a measure of the total charge capacity of a battery pack. Higher values can mean longer runtime AND might also indicate additional power. However, battery-powered mowers are generally designed with a current draw ceiling, so you typically won’t see double the power if you pair them with beefier battery packs.
What Kills the Battery on a Lawn Mower?
Numerous factors can lead to a lawn mower battery's continuous depletion or draining. Detecting these issues early can save both time and money.
- Loose Battery Cables: Over time, the constant motor vibrations can cause the bolts to gradually loosen, forcing the battery to exert extra effort to power the lawn mower.
- Dirty or Loose Wiring Connections: If you observe green or white corrosion around the connections, this could be the root cause of your battery troubles.
- Faulty Charging System: A malfunctioning charging system has the potential to deplete the battery.
- Defective Battery: A malfunctioning battery can also be a culprit behind recurrent battery drain.
- Ignition Key Left On: Neglecting to turn off the ignition key can contribute to battery drain.
- Corroded Battery Posts and Voltage Regulator Issues: These are commonly encountered issues that can lead to a draining lawn mower battery.
- Insufficient or Excessive Charging: Charging the battery inadequately or excessively can result in depletion.
- Worn-Out Components: If any components of the mower are worn out, they may cause the battery to discharge prematurely.
- Failure to Run the Mower at Full Throttle: Operating the mower below full throttle can hinder proper battery charging.
- Lack of Battery Maintenance: Inadequate maintenance, such as letting the battery sit in an undercharged state for extended periods, can result in crystal formation on the battery plates, reducing its ability to hold a charge.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about battery-powered lawn mowers in Australia.
Do battery powered lawn mowers last?
Yes, battery-powered lawn mowers do last. The lifespan of a battery-powered lawn mower depends on the type of battery it uses. Lawn mowers that use a 6 or 12-volt lead-acid battery should last about 3 to 4 years with proper care, whereas those with lithium-ion batteries can typically be expected to function for up to 5 years or 500 charging cycles.
Note that this can be influenced by how well they are cared for. Factors such as the way you use your lawn mower and how you maintain the battery can affect how long a lawn mower battery can last.
Do battery lawn mowers need oil?
No, battery lawn mowers do not need oil. They don't really need much in motor maintenance at all. Battery lawn mowers do not use oil, air filters, spark plugs, gasoline, or pull cords. The lack of maintenance is a huge selling point and a reason many people are switching to them.
Can battery lawn mowers cut wet grass?
Yes, battery lawn mowers can operate in wet or damp conditions. However, it's not advisable to use a battery-powered lawn mower on wet grass for several reasons:
- Safety: The battery-powered lawn mower is not waterproof. If you try to cut the grass when wet, the water can get inside and damage the electrical parts of your machine.
- Damage to the lawn and the mower: Wet grass can stick to the blades and cause them to become dull more quickly. Wetness will cause air bubbles to form on the blade, leading to crazing in the finish of the mower. There is a chance of rust forming on the metal parts of the machine.
- Uneven cutting: The grass blades are cut unevenly by one that is not dry.
So, while using a battery-powered lawn mower on wet grass is technically possible, it's generally best to wait until the grass is dry to avoid these potential issues.
