A lawnmower is an essential yard tool that every homeowner should own, and it requires a lawnmower battery to operate. This equipment is excellent for pruning your garden’s complex hedges. While this tool is durable, a weak battery can cause your lawnmower to cease working. While gas and oil mowers are simple to operate, changing a lawnmower battery is a different story.
For many homeowners and renters, lawnmowers are necessary pieces of equipment. Even yet, unless you live in a tropical or subtropical area, you’re likely to leave your mower in the garage for months at a time. You risk a dead battery if you do so. For example, while lawnmower batteries can retain a charge for long periods, they eventually deplete. With a lawnmower battery charger and some forethought, you can ensure that your mower will be ready to go as the grass begins to grow.
With so many different types of lawnmowers on the market today, you’ll need to find out which one is ideal for you. Electric, riding, self-propelled, and gas-powered mowers are some of the alternatives. Before you buy one, think about the size of your yard, how easy it is to use, how reliable it is, and how attractive it is.
Do you have any concerns about the costs of such machines? It turns out that you don’t have to spend a lot of money to have a good mower. To save you time and effort, we’ve combed the market for the best lawn mowers and reviewed various top brands of mowers. You’ll have an easier time picking one that matches your needs after reading our list of the finest lawn mowers for your yard.
Many households turn to battery chargers because they are environmentally friendly, simple to operate, and frequently just as strong as their gas-powered counterparts. Lawnmowers that run on batteries are becoming increasingly popular, with more top-name brands developing their electric models. If you’re considering a battery-powered mower, consider how long it will take you to mow your grass. The runtime of these mowers varies from 30 minutes to several hours, and depending on the size of your yard; you can choose between walk-behind and riding models.

Battery Tender Junior 12V Charger
Rather than being a lawn mower battery charger, the Battery Tender Junior is designed for battery repair. Because this version’s output is 0.75 amps, it could take several days to charge a flat battery fully. When the charger is plugged in, it goes through four stages of setting: initialization, bulk charging mode, absorption mode, and float mode. This method fully charges the battery without overcharging it, and it can be securely left attached indefinitely.
The float mode maintains the health of your battery and keeps your lawnmower ready to use at all times. When your lawnmower isn’t in use throughout the winter, this is the ideal solution.
With a 12-foot charging line and a spark-proof connection method, connecting the Battery Tender is a breeze. You won’t have to worry about attaching the battery charger the wrong way up because it has a reverse polarity detector that protects both you and your battery. Simple indicators indicate the charge state of the battery. The LED will glow red when it is first connected. When the battery is fully charged, it turns green.

What Are the Signs That a Lawn Mower Battery Is Dead?
The lawnmower often won’t start the first time you notice an issue with the battery. If you hear a clicking noise, it’s a sign that the battery needs to be replaced. If your lawnmower won’t start, perform the following checks on the battery:
- The battery terminals should be examined first. Is there any slack in the cords, or are they perhaps disconnected? Tighten the connections before attempting to start the lawnmower.
- Check the water level in the battery cells while you’re examining the battery. Fill them up with pure water if they’re running low. Tap water contains minerals that are hazardous for your battery, so don’t use it.
- Check the battery charge if you have a multimeter. On the meter, an excellent 12-volt battery should register approximately 12.6 volts. Connect it to a trickle charger if it isn’t already connected. A meter reading of fewer than 10.5 volts indicates that the battery is likely beyond saving and should be replaced.
Charging Instructions
- Wear protective gear, gloves, and safety eyewear when working with wet-cell batteries because they contain acid.
- Disconnect the battery if the lawnmower will not be used for an extended period.
- To charge the battery, connect it to the charger. The positive red lead of the charger must be linked to the positive battery terminal, at the same time as the negative black facts must be linked to the negative battery terminal. Some chargers can show a caution in case you connect them incorrectly.
- Connect the charger to the power outlet and turn it on.
- Calculate the battery’s charging time and disconnect when it’s finished to avoid overcharging. You can wait until the charger has completed its cycle if your charger offers a trickle charge and maintenance feature. For more information, consult the charger’s handbook.
- Try starting the lawnmower after reconnecting the battery. If the battery has failed to hold a charge, it must be replaced.
Frequently asked questions
How long does it take to charge a two-amp lawn mower battery?
The battery’s amp-hour rating determines this. For example, if your lawnmower battery is rated at 24 amps, it will take about 12 hours to charge from the flat fully.
Is charging a battery at two amps or ten amps better?
You can charge at a higher amperage for general recharging, and the battery will be charged faster. However, charging the battery too quickly and for too long can limit its life. When a battery is not in use, trickle charging at lower amps is commonly utilized to keep it alive.
For my lawnmower, what size battery charger do I need?
It’s critical to utilize a suitable lawn mower battery charger. Most lawnmower batteries are now 12 volts. However, some 6-volt batteries are still available. Check to see if 24-volt batteries are available before purchasing. Many battery chargers on the market can automatically recognize whether the battery is 6-volt or 12-volt. Slow trickle charging is the most fantastic method for charging power. Your battery’s performance and life will be harmed if you charge it quickly at a high amperage.
Can I use a car charger to charge a lawnmower battery?
If your lawn mower’s battery is a conventional 12-volt battery, a standard 12-volt battery charger will suffice.
What is the expected life of a lawnmower battery?
Generally speaking, your lawn mower battery should last between three and five years. However, proper maintenance might help your battery last longer. Batteries are frequently left unused for six months or more, which can be fatal. On the other hand, a battery maintainer may be able to save it and help it survive much longer.
Is it possible to charge a lawnmower battery with a car?
Yes, for the most part! Many modern lawnmowers use the same 12-volt batteries as are used in automobiles. As long as the battery is in good condition, it should charge without being overcharged.
Buying guide
Purchasing a new lawnmower battery charger does not have to be complicated. Before reading our review of 5 lawn mower battery chargers, make sure to read our buying guide. It will make finding the best one much easier and faster.
Voltage:
First, determine which voltage you require. It might be six volts, twelve volts, or twenty-four volts.
Safety features:
The various chargers offer a variety of safety measures, and we also review one that can charge four batteries at once.
Connector style:
Do you require a specific connector, third? This is commonly found on cordless lawnmowers.
Type of Charger:
If you have a lead-acid battery, you can select the most appropriate charger for your needs. Look for one with a maintenance mode and can be permanently linked to the battery in this scenario. This will offer your battery the longest possible life and may even be able to resurrect a battery that appears to be dead. A current of around 2-amps is recommended for trickle charging batteries, although you can use up to 8-amps. The lower the amperage, the longer it will take to recharge the battery.
Bottom lines
Connecting a quality battery charger to your lawn tractor’s battery is the greatest method to make your life easier during the cold winter. When purchasing, look for one that can recharge your mower’s battery as well as features that meet your needs. The alternative way is to use a jumper cable – assuming you have a compatible battery, which is far more complex.
