Best Battery for Lawn Mower Reviews

1. Mighty Max Battery ML-U1-CCAHR for John Deere

Established in 2006, Mighty Max Battery is now one of the most trusted names in the cordless lawn mower power source game.

It specializes in gel-cell batteries, sealed lead-acid batteries, lithium batteries, and solar panels.

The ML-U1-CCAHR 12-Volt Battery is part of its extensive battery lineup and is the company’s mid-tier offering.

It is an excellent power supply source for the John Deere X320 electric mower and other commercial mowers like Cub Cadet.

If you do not like the gas emissions from gas engines, this is the way to go.

Product Highlights

Battery-powered lawn mowers generally cost a bit more than their gas counterparts, but they are worth every penny.

That is especially true for the John Deere X320, a reliable battery-powered tool for your garden.

If you own this or other cordless mowers like it, you should consider buying the ML-U1-CCAHR from Mighty Max.

It has all the basic and additional features that people look for in a cordless lawn mower power source.

  • Cold Cranking Amps

One of the many things that make this battery stand out is its high cold-cranking amps rating.

Otherwise known as CCA, it describes the amount of current that rechargeable batteries can deliver at extremely low temperatures.

If you live in an area with cold temperatures, you should consider getting one of these sealed lead-acid batteries.

This particular model from Mighty Max has an impressive CCA rating of 320.

It is higher than other sealed lead-acid batteries, which typically range between 250 and 280.

On top of this, it allows you to cover a lot of ground with your battery-powered riding mower on a single charge.

  • Deep Cycle Discharge

It is common for electric riding mowers or cordless lawn mowers to sit idle in the garage for long periods.

This is especially true during winter when grass grows at a much slower rate. During this time of the year, it is better to avoid mowing, especially on wet grass.

However, even when your battery-powered mower is not in use, it will still get fully discharged over time.

The good thing about the ML-U1-CCAHR is that it can recover quickly from deep discharges.

In fact, it can survive repeated cycles of charges and discharges without incurring any damage to the plates.

That is because deep cycle batteries like the ML-U1 use plates that are thicker and more durable.

  • No Spills

Inside this Mighty Max battery, you will find durable separators that use absorbed glass mat technology.

As a result, it can resist vibrations much better than other sealed lead-acid batteries. It is also spill-proof, and you can mount it in any position.

This feature comes in handy if you want to use it on other electric lawn mowers with brushless motors.

The Good

The ML-U1 has a lot going for it, but what we like the most is its high CCA rating.

It can stand up to extreme weather and will crank quite easily even in sub-freezing temperatures.

The Bad

While it is an excellent power supply source for John Deere electric lawn mowers, you can also use it on higher-priced mowers.

That said, you might have to double check if it will fit the battery ports or if you can modify the battery cables.

Pros:

  • Has a high CCA rating
  • Impressive battery efficiency
  • Mountable in multiple battery configurations
  • Affordable price range
  • A single charge covers a sizeable area
  • Safer than a gas-engine mower

Cons:

  • Incompatible with some battery-powered mowers
  • Dual-port rapid charger not included

2. Chrome Battery 12-Volt Battery for Cordless Lawn Mowers

Chrome Battery has been around for over 25 years, making it one of the more reputable brands in the market.

It manufactures sealed lead-acid batteries, car audio batteries, batteries for power tools, battery chargers, and more.

This lawn mower battery is a mid-tier offering and is just one of its dozens of battery options.

It is a great battery for people who need a reliable lawn tractor but don’t like gas-powered motors.

Product Highlights

There was a time when the cordless model was seen as much weaker than gas lawn mowers.

If you have a larger yard, you almost always could not count on battery lawn mowers, much less a self-propelled lawn mower.

However, those days are long gone with the emergence of larger mowers and more powerful batteries like this popular Chrome Battery product.

  • Versatile Fit

One of the many reasons we like this battery is that you can use it for a wide variety of applications.

Like other sealed batteries, you can mount it in virtually any position without worrying about leaks.

It can fit in the battery slots of many lawn mower brands, including Husqvarna, John Deere, Voeller, Craftsman, and more.

You can even use it on alarm systems, scooters, and other types of equipment.

With a 12-volt and 35-Ah output, it has more than enough juice to get the job done.

  • Maintenance-Free Operation

This battery is a workhorse that can replace almost any type of battery with T3 terminals.

It has a durable construction that uses lead calcium alloy and absorbed glass mat technology.

With this design, you do not have to worry about checking for leaks or refilling it.

What it offers is maintenance-free use, allowing you to focus on other, more important things in your yard.

  • Extended Service Life

Another thing you would like about this battery is that you can depend on it to work for a very long time.

It goes through strict quality tests, ensuring it can handle most situations you put it in.

The exterior’s rigid construction can withstand rough handling and extreme conditions, and the interior is equally strong.

Even constant exposure to vibrations won’t be enough to cause damage to it.

You can also charge it up to 2,000 times, which is more than what some other models or brands offer.

It is a heavy-duty power source that will live up to the demands of maintaining large or medium-sized lawns.

The Good

The best thing about this product from Chrome Battery is its versatility.

It is a compatible power source with many battery-powered lawn mower brands, including the top ones.

You can even use it on other types of equipment aside from electric lawn mowers.

The Bad

This battery has no CCA rating and is not designed for engine starting.

Pros:

  • Suitable for multiple applications
  • Offers maintenance-free operation
  • Provides long service life
  • Safer than a gas-engine mower
  • Impressive runtime per charge

Cons:

Nothing beats using an original part if you want to replace something in your lawn mower.

The battery is no exception, as it is optimized for power tools and equipment of the same brand.

Using matching components and equipment guarantees that your machine will work as designed.

It also helps ensure you get the most in terms of performance and durability.

For instance, it will fit the battery compartment of various Craftsman electric lawn mowers.

Some users have also reported it is compatible with Sears mowers.

To ensure this battery is suitable for your unit, contact the seller first before purchasing.

  • Compatible With Charging Ports

Another thing you would love about this battery is that you do not need a separate charger.

If it is compatible with your lawn mower, you can just use the charger that comes with it.

The Good

This battery is an original part, so it works best if you have a Husqvarna lawn mower.

That said, it is also a compatible power source for some other battery-powered lawn mower brands and models.

The Bad

While this power source is compatible with other brands aside from Husqvarna, it is a bit limited in terms of application.

Your best bet is to contact the seller first if you doubt it will fit your lawn mower.

Since then, it has become an omnichannel business with various products to keep your lawn beautiful throughout the year.

You should also choose this if you do not like the noise levels or harmful emissions of a typical gas mower.

Product Highlights

This product comes with a lithium-ion battery that provides 24 volts and two amp-hour of power.

You can use it to power your Snow Joe lawn mower, but it is also compatible with other Sun Joe products.

With this feature, you get much flexibility even if you cannot use your battery on other brands.

  • Great Value for Money

While this starter kit is a bit pricier than the others, it holds one key advantage.

The package includes one slide-in battery charger that can revive a spent battery fully with charge times of 80 minutes or less.

You could also use this quick charger to charge other Sun Joe or Snow Joe batteries you may already own.

However, some users have complained that it won’t work when the temperature is a bit low.

It is not as efficient as a dual-port rapid charger. So, if you want to charge your battery quickly, do it inside the house where you have ample insulation.

  • No Memory Effect

Another great thing about this battery is that it has no memory effect.

With traditional batteries, you have to wait until they are drained or depleted before charging them.

Moreover, you must wait until they are fully charged before using them.

This is not a problem with the Snow Joe battery starter kit.

You can charge or use it whenever you need to without worrying about causing long-term damage.

If you already have a working charger and do not need another one, this starter kit might be a bit expensive.

Pros:

  • Comes with a charger
  • Works on Snow/Sun Joe products

Buyer’s Guide

There are many reasons to choose a battery-powered standard mower over a fuel lawn mower. However, you need a reliable spare battery to mow a large area.

Here are the most common characteristics to look for when shopping around for an extra power source.

Size and Location of Terminals

One of the first things you need to look at is the size of the battery.

It will determine to a great extent if your mower’s battery compartment can accommodate it.

You should also check the location of the terminals so that you can make any preparations if needed.

Material and Construction

The previous generation of batteries is a bit prone to leakage, but newer models are safer.

Just make sure that the battery uses a glass mat or gel cell technology before buying it.

Power Output

Most electric lawn mowers use 12-volt batteries, so you should check this before clicking that Add to Cart button.

It is also best to check the amp hours of the battery since this will determine how fast it will discharge.

CCA Rating

Not many brands provide their product’s CCA rating.

That said, if you could get this information, it would tell you how the battery will perform in cold sub-freezing temperatures.

Maintenance Requirements

Among the biggest challenges of older models was maintenance.

The best battery for lawn mower equipment is made using the latest technology and does not require any maintenance.
