FAQs about Lawn Mower Battery
1. How long should lawn mower battery last?
A fully-charged lawn mower battery can run continuously for at least 1 hour, which is enough to mow 1/2 acre of grass. Generally, the battery can be recharged about 500 times before you need to replace another one.
It also depends on how much you use the mower and the specific type of battery you choose. In fact, many manufacturers claim their battery’s lifespan base on hours of usage. You might need to get a new lawn mower battery within only 3 years, whereas others might be after 7 years.
2. Are all lawn mower batteries the same?
Not all of the batteries are the same. There are two types of lawnmower batteries: Lithium-Ion and Lead-acid batteries.
Lead-acid batteries were used long before Lithium-ion batteries were invented. The highlight of this type is its capacity to provide a steady, stable current of electricity in a long while. They also function better than Lithium in cold weather (under 32 degrees Fahrenheit).
But lead-acid batteries charge slowlier and have a generally shorter lifespan than Lithium ones. Lithium-ion batteries, on the other hand, are known to last longer, have faster charging, and can store more electricity. Their charging cycle is up to 500 times, whereas lead-acid batteries are only around 200-300 times.
3. Can you recharge a dead lawn mower battery?
You can recharge the dead lawn mower battery by connecting it to a charger. In case you are unclear about the volt to set on your charger, 12 volts is considered standard. Check back after 8 hours, if you find your battery didn’t charge up, it’s time to buy a new one.
4. How to know your lawn mower battery is dead?
When you start your lawnmower, if there is no clicking sound, or the engine won’t crack, chances are its battery is dead. You can also use a multimeter to check the battery’s voltage, any number lower than 11.5 volts is a clear indication that your battery has reached its time.
5. How do I know if my lawnmower battery is 12-volt?
You can calculate the volt of a lawnmower battery by counting its plastic caps, then multiple the number by 2. For example, a battery that has 6 caps will have 12 volts.
6. How long does it take to charge a 12-volt lawn mower battery?
A standard 12-volt lawn mower battery will take about an hour to be fully charged. But this number is only correct with the right type of charger you use. A typical 10-amp charger is what we are talking about. If you use another charger with lower output, it may take longer to fully charge your battery.
7. How often should I charge my lawn mower battery?
There isn’t a concrete answer to this question, instead, we highly advise you to follow the instructions from the manufacturer for each type of battery you are using.
Another recommendation from experts is to not operate when your battery is running low (below 20%). When the battery reaches 20 percent, it is also the best time to give it a charge, rather than 0 percent like most people do. This will help outlast the lifespan of your lawnmower battery.
