Battery-powered lawn mowers are easier to use than corded models and more eco-friendly than riding gas mowers.

Modern versions also have a longer service life and could last several years.

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 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.

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.

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.

Among the biggest challenges of older models was maintenance.
