Best Lawn Mower Battery Charger Comparison Table
Top 5 Lawn Mower Battery Charger Reviews
1. 24-Volt Lawn Mower Battery Charger by Earthwise
- 24 volt;
- Indicator light.
To be honest, this is not a genuine Earthwise charger, rather a close dupe of it. The genuine one comes with a higher (3 amp) amperage and a better quality. Needless to say, the price is also higher for the real one.
This dupe 24-volt charger has all the facility as the real one and even backed by a long warranty. It is affordable too. To charge a battery of fewer than 24 volts, this inexpensive charger will surely work well. Its amperage is a bit lower side, so it takes time to get charged fully. Besides, the charging indicator light can’t be seen in broad daylight.
Despite these, the charger itself is okay to charge low voltage and low amperage batteries like a lawn mower and so on.
- Long warranty;
- Not the genuine one;
- The indicator light is difficult to read during the day.
2. 15 volt Lawn Mower Battery Charger by AYP
- 15 volt;
- 0.3 amp.
If you own a lawn or deck mower of widely used brands, then you must need a charger from popular makers as well. This charger from AYP is compatible with mostly used lawn mower brands and is a great replacement for chargers of different models. Whether the mower you are using is from Poulan Pro, Poulan, Craftsman, Roper, Sears, Husqvarna, Weedeater, Rally, EHP or Yard Pro, this charger will serve you right.
Initially, it will take 2 days to fully charge a fully drained mower battery. But once it is done, your battery will be ready to do 10 to 20 mowing sessions without a hitch. The price of this charger is much lower in Amazon than the local stores. So, place your order right away if the brand of your lawn mower matches with the list.
- Compatible to leading brands lawn mower batteries;
- Cheap price;
- Low amp.
3. 6V/12V Automotive Battery Charger/Maintainer by BLACK+DECKER
- 12 volt & 6 volt;
- 1.5 Amp;
- Battery charger and maintainer.
This charger is the most versatile one among all the charges I have reviewed in this list. Apart from your lawn mower, from RV to motorcycle, boats even snowmobile batteries can be charged with it. Most people keep this charger connected with their vehicle and charge their lawn mower battery when required. For easy connections, both alligator clamps and O ring terminals are included with it.
The feature that makes it versatile charger is, its slide-on switch that lets you charge 6 and 12 volts batteries whether it is GEL, WET or AGM type. There is no need to buy a separate charger just for different applications. This charger will charge almost every vehicle battery one can possibly own. Surprisingly, the price is just like other lawn mower battery charger, nothing expensive.
- Versatile use;
- Compatible to AGM, Gel and Wet batteries;
- Overcharge and short circuit protected.
- Gets warm while charging.
4. 12-volt Smart Charger for Wet, AGM, Gel, Cell, and Lead Acid Batteries by Mroinge
- 12 volt, 1 Amp;
- 4- stage charging.
The features of this charger are much like our top pick Black and Decker charger. The difference is, it has only one volt. So, if your lawn mower battery is 12 volt or lower, then this review is for you. It is a good battery charger and even better battery-maintainer. The charger is 4 stages to protect the unit from short circuit, overload, reverse polarity and even from overheating. It is literally a ‘plug and play, then forget it’ deal.
Its amperage is lower than the top pick so it will take a while to charge a drained battery. But mostly we never disconnect our chargers from automotive batteries, so that’s not gonna cause any trouble. This charger will automatically shift to ‘float’ mode whenever the battery is full and it will return to ‘trickle’ mode when the battery needs to be charged. All these facilities along with protection are available in a budget-friendly price.
- Long DC cord;
- Auto float mode;
- Works with any vehicle battery;
- Charge and maintain.
- No cons.
5. 12 Volt Junior Automatic Battery Charger by Battery Tender
- 12 volt, 1 Amp;
- 4- stage charging.
For a safe and solid charger for lawn mower battery, this charger from Battery Tender is a wise option. It is solid because it is lightweight, compact and backed by an incredibly long warranty.
On the other hand, it is safe to use because, it is well protected from possible damage from overcharging, overheating, short circuit and a plus, from sparks. Almost all chargers in the market claim to be well protected from these problems, but none say they are spark proof. Connect the two clamps of this charger and prove it yourself; they really don’t spark.
My tip for people who have long and chiller winter is to keep it plugged into the lawn mower battery if you don’t want the battery to dry up upon not being used for a long time. This charger is even better as a maintainer. So, keep it plugged in and sleep peacefully.
The price is on the higher side, but for a long warranty and helpful customer care, this charger worths the price. Because it may save you from purchasing another one if it gives out before the warranty and let you claim a replacement.
- A long warranty offered;
- Amazing customer service;
- Lightweight and compact;
- Spark proof.
How to Know the Battery is Dead
Sometimes you may get confused if the tractor battery needs to be recharged or not! Because it can lose its charge during winter while stored for months without using. You can make them work by charging for only a few hours but how can you know it is dead or not working for any other technical fault!
Well, you can know that by following these simple steps-
Sit on your lawn tractor and depress the clutch then turn its key if the engine doesn’t crank or crank slowly or makes noises, your battery is dead.
Now turn off and remove the key. Then find out the battery, shake the cable gently and make sure that they are well connected to the battery. If not, tighten them with a wrench and start again.
If you’re using a wet- cell battery, you can remove the caps with a flathead screwdriver and check the water level. If it isn’t full, refill the cells with distilled water.
Recharge the battery for 6- 8 hours. If it doesn’t indicate full charge within 8 hours, you may need to replace the battery.
How to Charge Lawn Mower Batteries
It’s very common to find a dead battery at the beginning of your lawn care season. The reason for a dead battery is to remain the cables connected with the battery when the tractor is not in use.
But you can make them run again like before just by recharging them with the right type of lawn battery charger.
To charge your tractor battery, you can follow these steps,
Always charge your batteries in an open or well- ventilated space, not in an enclosed area.
To avoid any injury or damage to the tractor, never touch the terminals with bare hands and don’t bridge the terminals with any tool or other types of the conductor.
Always follow the manufacturer’s instructions before charging you tractor battery.
Choose the Charger
For choosing the right charger, you need to consider the volt of the battery. Generally, a modern lawn mower comes with 12-volt batteries. And most battery chargers are able to handle a certain range of voltages, they allow you to switch between the voltage that is suitable for your battery.
You may have a charger with few additional settings like- Trickle/ fast charging, 2 amp slow charge option/ timed charging, jump mode. Among these options, the 2 amp charging option is the best option for lawn mowers because it allows a thorough and deep charge.
Charging the Battery
Connect the charger cables to the battery before connecting them to the power outlet. And for connecting with battery, hook up the positive cable first, you can identify them by its red color or look for the (+) symbol. Then hook up the black colored negative cable with (-) symbol.
now set the charge rate on your charger and plug it into the power outlet. Generally, it may take 4- 6 hours to be recharged fully.
Disconnect the Charger
When the charge is completed, switch the charger off if it comes with an off switch then unplug it from the outlet. If the charger doesn’t have an off switch, unplug it from the outlet after completing recharging.
Before disconnecting the cables from the battery, wait a few minutes to disperse any accumulated gasses. After a few minutes, unclamp the negative then the positive cable from the battery.
Hope this will help you to select the right charger for your lawn mower battery and you’ll be able to check and charge it properly.
But always remember, while buying a charger and charging the battery, you must follow the instructions provided by the manufacturer to avoid any unwanted accident or damage to yourself and the battery.Lastly, if you need to replace your lawn mower, you can check a detail list here.
