How Long Does It Take to Charge a Lawn Mower Battery? (Find Out)
If you have an electric lawn mower for your lawn, it is powered by a battery. No matter what type of battery your mower uses, you will eventually need to recharge it. Because the battery ran out of power from use or lost charge while sitting during the winter. It’s crucial to understand how long to charge a lawn mower battery.
The electric mower is one of the more often used types of lawnmower. Initially, only small lawn mowers were available, but today, larger sit-on electric lawn mowers are also available. No fuel is used and significantly less maintenance for electric lawnmowers.
How Long To Charge Lawn Mower Battery
There isn’t a single universally applicable charging time for all batteries. But some general rules you can use to gauge how long it will take to charge a lawn mower battery. You need to know the voltage, amp-hours, voltage, and amperage of your battery charger to calculate the battery to charge.
Depending on this information, charging times can vary greatly. Multiply the amp-hours rated by the number of amps your battery charger provides to calculate how long it will take your battery to charge.
Small Lawnmower Batteries Time
| Mower | Company | Battery-Type | Charging Time | Cutting Time |
| Push Mower | Snapper | Lithium-Ion | 30 Minutes | 25 – 30 Minutes |
| Light Mower | Sun-Joe | Lithium-Ion | 1.5 – 2 Hours | 45 Minutes |
| Smaller Sit On Mower | Cub Cadet | Lithium-Ion | 4 Hours | 1 Hour |
Large Lawnmower Batteries Time
| Mower | Company Name | Battery-type | Charging Time | Cutting Time |
| Self-propelled | LEO | Lithium-Ion | 2 Hours | 50 Minutes |
| Big Sit On Mower | Cub Cadet | Lithium-Ion | 4 Hours | 1.5 Hours |
| Big Sit On Mower | Weibang | Lithium-Ion | 12 Hours | 2.5 Hours |
Charger Feature
A relative quantity of lawnmowers, including the best 30-inch riding mower, is powered by lead-acid or lithium-ion batteries. But the type of lawnmower battery you have, maintaining your lawnmower batteries benefits from your understanding of its charger characteristics.
Voltage
Use a charger with the same voltage as your battery when you charge it. Your battery will either get ruined or unable to charge if the wrong voltage charger is used. It is very simple for your battery to overheat and malfunction if, use a 12-volt charger on a 6-volt battery.
It’s not a good idea to charge a 6-volt battery with a 12-volt charger. On either side, a 12-volt battery will not give power when a 6-volt battery charger is used with it. In this situation, 12-volt batteries are still regarded as completely dead even when their voltage drops to barely 10 volts.
Amperage
The determinants of charging times are unquestionably the amp-hours your battery is rated for and the amperage your charger produces. Batteries for 6 and 12-volt systems come in a wide range of amp-hour ratings and offer numerous amp output options.
Your battery and charger do not need to have the same amperage, unlike with voltage. The rule of thumb is that your battery charger shouldn’t have more than 20% of your battery’s amp-hour (Ah) rating.
This is best to use a battery charger that is 8 amps or less for a 40Ah battery. It is beneficial to use a battery charger that charges slowly for your health. However, a charger that is too powerful can potentially damage your battery, avoid using one.
Charge A Lawnmower Battery Properly
Use the following method to charge your lawnmower battery properly:
Observe Fundamental Safety Precautions
To protect yourself from an electrical accident, charge your battery while wearing safety goggles and heavy work gloves. You should look for damage to your mower’s electrical system, like frayed wires, a swollen battery, and other issues.
Track Down the Battery
The battery is typically buried under the seat of mower types. Search for the positive and negative battery terminals by raising the seat. Lawnmowers don’t have the same construction, and each model has different characteristics. Most manufacturers have online resources to get answers if you’ve lost your handbook.
Organize The Cables
Connect the red wire to the positive battery terminal and the black one to the negative terminal after you’ve located your battery. Start with the positive endpoint every time.
Give The Battery Rest
Gases are produced when your battery is in charging mode. If you don’t wait for the fumes to diffuse, they harm both your mower and your health. You should give yourself at least five minutes to wait before removing your charger cables. Lead-acid batteries frequently have gas problems. You can skip this step if you use a lithium-ion battery.
Turn Off the Charger
You can remove your charger from the outlet once the gas has passed. Before removing the positive cable from the battery, disconnect the negative charger cable. Connect the terminals, start with the positive cable and move to the negative cable, after reinstalling the battery in the housing.
Useful Features
If you invest in a contemporary lawnmower battery charger, you don’t need the health risks associated with older chargers. Based on the model you choose, you can select a range of cutting-edge features, such as the following:
- Several modes, including jumpstart, quick charge, and slow charge
- Connection failsafe to stop erroneous hookups
- Timer for integrated charging
- Automatic termination
- Clamps for various connections types
- Float mode charging for best results
- Regulated amp rates
Not every charger available today has every one of the good qualities. But if you want to increase the battery life of your lawnmower, spend money on a charger that offers many features.
Factors that Affect How Long a Lawn Mower Battery Takes to Charge
You probably do not use your lawn mower often if you are like other people. Ensure that your lawnmower will start and function properly when you do need to use it, and the battery is fully charged.
The type of battery, the charger’s voltage, and the charger’s amp-hour are a few variables that affect the response. There are various battery kinds with chemistries, and the type of battery affects how long it takes to charge. Lead-acid batteries are the most popular type of batteries used in lawnmowers.
It takes these batteries eight hours to charge fully. It will take longer to charge your lead-acid battery if you’re using a gas-powered generator, which takes 12+ hours. The majority of chargers either output 6 or 12 volts, with 12 volts being more potent.
Your battery will charge more quickly with a higher voltage charger than one with a lower voltage. It will take four hours to fully charge a lead-acid battery from empty if you use a 12-volt charger.
To accomplish the full charge on your lead-acid battery with a 6-volt charger, it’ll take twice a long time. The amp hour rating on your charger affects how long it takes for your lawn mower battery to charge.
While using a 12-volt 2-amp charger connected to the grid via an electrical outlet, you can anticipate a lead acid battery to partial charge in around four hours. Manufacturers do not advise “rapid” charging of lead acid batteries because it can shorten the battery’s lifespan.
