Understanding Battery-Powered Mowers
Battery-powered lawnmowers are a type of lawnmower that uses rechargeable batteries as their primary power source. 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 lawnmowers:
Power Source, Runtime, and Charging
Battery-powered lawn mowers have one or more lithium-ion batteries that store electrical energy. These batteries are located on or near the mower's deck and provide power to an electric motor that drives the blades.
The battery runtime depends on the battery capacity and the lawn size. Smaller lawns often 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 recharge usually takes a few hours.
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 gas mowers and electric mowers. They offer consistent power without the emissions of gas mowers but with a limited cord length. Their decision 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 manoeuvre. 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 than 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 must replace the batteries regularly. Lithium-ion batteries have a limited lifespan and will need replacement after a certain number of charge cycles.
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 other devices; thus, it's common for residential-grade battery-powered lawnmowers to employ a dual 18V battery setup, resulting in a 36V system. Nevertheless, we do not recommend them for commercial 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 a battery pack's total charge capacity. 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.
- Constant motor vibrations can gradually loosen bolts, causing the battery to work harder than necessary to power the mower.
- Corrosion (often seen as green or white buildup) around wiring connections can disrupt power flow and lead to battery issues.
- A malfunctioning charging system may fail to replenish the battery or even drain it, resulting in repeated power loss.
- A battery in poor condition can cause frequent draining and reduce overall mower performance.
- Forgetting to turn off the ignition key can continuously draw power from the battery, leading to premature discharge.
- Corrosion on the battery posts or problems with the voltage regulator are common culprits behind a draining battery.
- Undercharging or overcharging the battery can degrade its capacity and lead to quicker depletion.
- Worn or damaged mower parts can place extra strain on the battery, causing it to discharge faster.
- Running the mower below full throttle can prevent the charging system from working effectively, leaving the battery undercharged.
- Allowing the battery to remain undercharged for extended periods encourages crystal buildup on the plates, which diminishes 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 its battery type. Lawn mowers that use a 6 or 12-volt lead-acid battery should last about 3 to 4 years with proper care. In contrast, those with lithium-ion batteries can typically be expected to function for up to 5 years or 500 charging cycles.
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.
