Do you know how long it takes to charge a lawn mower battery in 2023? Well, you will find out in this article today.
One important question that may be on your mind regarding a battery-powered lawnmower is “How long does it take to charge a lawnmower battery?”
Overcharging, like undercharging, is one of the surefire ways to destroy your lawnmower battery. And since the efficiency directly depends on the battery, you cannot afford to take chances regarding charging the battery.
You need to know some basic maintenance tips to preserve your battery life and don’t bother yourself, because, in this piece of content, we have explained every detail you need to know about your lawnmower battery. Let’s go!
How long does it take to charge a lawn mower battery?
The outset of summer comes with a need to get your lawnmower out, so your yard can be properly manicured. If your mower was stored throughout the colder months, chances are that the battery would have drained, and you want to get the battery charged throughout the season so that you can finally run your mower on the lawn.
A regular lawnmower that is fully charged will last for an average of one hour. Charging a lawnmower fully, especially with a trickle charge, is more time-consuming but will downturn the battery’s charging frequency and ultimately enhance its health.
Looking after your lawnmower’s battery will maintain its life, but several factors are involved in charging it. Consideration of your lawnmower’s battery, you must realize, is as important as that of the lawnmower itself.
The next section of this article discusses what affects your lawnmower charging time.
Factors affecting Mower Battery Charge time
Three important things can interfere with your lawnmower’s battery charging times;
The voltage of the battery
The required amps to get it charged
How often do you use it
These three things will affect how long you need to charge your battery. To better understand your battery and how it charges, you need to know how voltage and amperage work.
The Battery’s Voltage
Every battery comes with two terminals; positive and negative electrical charges. The voltage is the difference between the potentials of the two terminals.
The voltage your lawnmower’s battery dissipates will affect how long it has to charge and how long it stays on in between charges. Your lawnmower battery’s voltage is dependent on the following three (3) factors;
The size of your mower
Your mower’s production date
How often do you use your mower
Eighty percent of lawnmowers use a 12-volt battery. This voltage is ideal for lawnmowers because it can get the machine working while forestalling the occurrence of shocks to the owner and can last for some hours of use.
Lawnmowers, whose production dates back to 1980, will probably utilize a 6-voltage battery with a briefer charge and usage time.
Role of Amperage in Charging
Another key factor in your lawnmower’s battery charging time is its amperage. It is the intensity of the currents measured in amperes, also known as “amps”. What the amps do is, measures the current that charges the lawnmower’s battery.
The typical charger for your lawnmower’s battery comes with a current of roughly ten amps. With a lower current, your battery will take longer to charge than a higher current. But there’s a reason this current is recommended; to protect your battery life.
Some chargers will charge your lawnmower battery at a current of 20 amps, reducing its charging time. The con of output as large as this is; that it can damage the battery, especially if it goes through regular use.
Seven amps current or less is easily the best; of course, your battery will take longer to charge but will, at least, be able to last long. If you are charging your battery at 6 or 7 amps, you should be able to use it within one hour. Increasing or decreasing the current will extend your battery’s charging time.
Do you see why a seven amps charger is the best? Not only does it aid your battery’s life by down-turning the current, but it also gives it a faster charge time than lower amperes.
The Frequency Of Use
How often you operate your lawnmower can directly affect the battery’s duration. While your battery may stay charged while in storage, there is a counter tendency for it to drain, even though it is not necessarily in use. If you did not use your lawnmower all winter, you may be unable to power it immediately.
Some battery drainages are not out of place, especially if it is not connected to major issues such as;
Leaving the mower powered
Keeping keys in the ignition
Age-related current draw
If you leave your mower keys in the ignition, you could risk forgetting to turn the mower off, and the mower can also be left in standby mode. What you would be doing, in this case, is channeling extra power away while you think it is stored.
One way to avoid this is by double-checking to ensure the keys are off the ignition after using the lawnmower. Another thing you may want to confirm is that there is no unneeded current draw when the lawnmower is deactivated, as older batteries tend to lose charges much faster.
If your battery consistently drains quite quickly, you might want to consider getting a replacement. A working battery will conserve most of its charge without excessive leakage. The more your lawnmower leaks, the terrible the battery’s condition becomes.
Can your Mower’s Condition Affect the Battery Life?
Yes, it can. Taking proper care of your lawn has a positive influence on your battery. And how do you take proper care of your lawnmower? By running a regular check-up on the engine and the blades, and keeping an eye out for the battery condition.
What you would be doing by taking care of the whole machine is, extending your lawnmower’s battery life while also sparing yourself the dollars you could have spent on repair or a replacement.
Highlighted below are some of the tips you need to care for your lawnmower and, by extension, its battery life;
Keep your blade sharp
Keep your lawnmower properly as the weather demands
Do not mow wet grass
Do not run over big debris in your yard
Can you Trickle Charge your lawn mower battery?
A trickle charger is an awesome alternative to regular chargers, which will deliver a current of up to 10 amps to the battery. As for trickle chargers, they will charge your battery very slowly but will protect it in 3 ways;
Preventing overcharging
Disallowing the battery from draining
Protecting the battery from temperature and sulfate hazards
These chargers deliver 1-3 amps to your 6/12 volt lawnmower battery and are mostly automatic. As soon as you attach the charger, it will pick your battery’s voltage and charge level to maintain it.
The charger will, from there, take care of the battery. To charge your lawnmower battery full will take close to 24 hours on a trickle charger.
Bottom Line
Everything begins to change the moment you understand that the condition of your lawnmower can make or mar the battery life. One important way to maintain this battery is by charging it.
And here is where basic tools like trickle chargers come into play. All you have to do is connect it; it does the rest of the work for you.
