Lawn Tractor Buyer’s Guide

Buying a battery for a lawn mower is a serious endeavor. You need a battery that is reliable and delivers enough power to ensure it’s ready to tackle your lawn without hesitation.

Many considerations depend on the type of lawn tractor that you have, whether you’re using a John Deere or another manufacturer’s tractor.

The main specs you should look into include:

  • Size
  • Terminal position
  • Type
  • Voltage
  • Amp hours
  • Construction
  • Return policy and warranty

The best lawn tractor battery is appropriate for your lawn tractor in its size, weight, and design. It will provide enough power to start reliably, no matter what the weather.

Other things to consider are the cold-cranking amps, charging cycles, and maintenance.

Let’s discuss each one in detail.

Size of the Lawn Tractor Battery

Tractor batteries come in a variety of sizes, which means that not all products will fit.

Most manufacturers will provide these specs since it can put even the best lawn tractor battery in the dealbreaker category. The essential thing is that it sits properly in the lawn tractor.

You shouldn’t have to stretch the battery cables to get them on the battery. Even though they are likely coated with a protective material, they can still fray from the jarring motion of a lawn tractor.

Most tractor batteries are about 7.7 inches long by 5.2 inches wide by 6.9 inches high.

Our advice is to measure the available space to be sure of the fit for the battery for lawn mower.

Terminal Position

The terminal position is related to the above factor. The size you’ll see most often is U1 batteries, which have their positive terminals located on the left side.

On the other hand, U1R batteries put them on the right. Make a note of which type of lawn tractor battery you have while you’re measuring it.

Type

There are three main types of batteries that will power larger electronics and devices like a lawn tractor. They include:

  • Flooded lead-acid (FLA)
  • Sealed lead acid (SLA)
  • Lithium-ion

The FLA batteries provide reliable power and charge quickly.

On the downside, there is the maintenance. You have to monitor the water levels in these batteries. They are not sealed, which means they can leak. There is also the off-gassing of the sulfuric acid-water solution within the battery.

An SLA battery will also charge reliably. Its primary advantage is that there is no maintenance because they are sealed. All the batteries we reviewed are sealed lead acid. These products come in three flavors:

  • Gel cell
  • Absorbed glass mat (AGM)
  • Sealed valve-regulated wet cell

All the batteries we reviewed used AGM technology. The benefit of these products is the use of absorbed glass mats with fiberglass to separate them, which gives it an edge when handling vibrations and shocks.

It’s a desirable feature for lawn tractor batteries.

The gel cell battery uses silica within the casing that makes them a better choice for the best battery in warmer climates. The sealed value-regulated wet cell batteries are essentially an FLA battery without the maintenance.

Battery Voltage

This figure describes the amount of current coming from the battery. The most common battery voltage you’ll see on batteries for lawn mowers is 12 volt.

It’s the same size you’ll see for your car, too. You might see some batteries that are higher, going to 24 or more volts. These products are appropriate for other uses, such as an RV or solar panel setup instead of a lawn tractor.

Amp Hours

Amp hours measure the capacity of a battery. The higher the figure, the greater it is. Most batteries run in the range of 3 to 20 Ah.

The ideal spec depends on the type of lawn tractor you’re running. More isn’t necessarily better than the recommended amp hours, considering how you use a tractor.

A higher capacity is desirable if you’re going to use your device for long stretches or during colder times of the year.

Construction

The construction and design of the battery is a vital consideration when thinking about the value of your purchase.

The material should be non-conductive. It’s also essential that it’s durable to handle the rigors of driving your lawn tractor over rough terrain.

Many manufacturers use plastic polymers, which are both sturdy and affordable. They can also cut down the weight of the battery so that it’s easier to install.

Return Policy and Warranty

Whenever we buy anything online, we always check the manufacturer’s policies on returns and warranties, even with the best lawn tractor batteries.

Most will offer at least a 2-week interval to send back a defective battery. We suggest that you pay attention to the fine print regarding shipping costs.

A reputable manufacturer will back up their batteries with a warranty. Most of the products we reviewed were covered for one year.

Again, be sure to read the terms. Some companies will refund your money for a limited window. Then, it’s a replacement for the faulty battery.

What is a Lawn Tractor?

Lawn tractors come in a variety of sizes and features. Their main advantage is convenience, especially if you have a large area to cover. In many ways, they are just like your car, using a battery to start them.

Lawn tractors vary in their cut width, which determines the optimal size for your yard. They can range anywhere from 30 to 60 inches or more.

Of course, you can get lawn tractors that can do more than mow. Optional attachments will increase the versatility and value of your purchase for tasks such as spreading fertilizer or hauling.

The technology of lawn tractors has improved in recent years, with features such as cruise control and zero-turn radius. Some even have things like lumbar support and cup holders.

How to Charge a Lawn Tractor Battery?

Charging your battery is an essential part of spring and fall care. Colder weather can sap the juice from the battery.

That’s why it’s imperative to put your battery on the charger before you run your tractor for the first time in the spring. The same advice applies to lawn tractor batteries in the fall.

The idea is to let it go into winter fat, i.e., on a full battery charge.

Today’s battery chargers will segue into a trickle charge once it’s fully powered. Many have an auto-shutdown feature, which will protect the life of your lawn tractor battery.

The ExpertPower Lawn Tractor Battery earns its place as the best lawn tractor battery in our reviews. It delivered reliable power with its spill proof AGM design.

This battery is maintenance free in a manageable size that is easy to install in lawn tractors. We especially like the extra long refund window on the best lawn battery.

The Chrome Lawn Tractor Battery stands out as the best battery for long-term performance in a sealed lead acid product.

The Chrome battery also uses AGM technology in the 12 volt powerhouse. If you need a more powerful battery, the Chrome battery is an excellent choice for reliable performance with no maintenance necessary.

The Mighty Max Lawn Tractor Battery earned high marks for the best value in batteries for lawn mower.

Like other sealed lead acid tractor batteries, it is maintenance free and spill proof with its glass mat design. The price is right, too, which makes it an excellent buy.

The remaining batteries stand out with their AGM design, which makes them a smart choice for a lawn mower battery.

They can handle uneven terrain without risking the lifespan of the battery or spilling its contents. They charge quickly, too, so that you can bet back to work fast.

You’ll find products of varying sizes and amp hours to serve a variety of landscaping tasks. We suggest that you consult your owner’s manual to determine the specs that you need for your device, including its size.

All the batteries include at least a 30-day refund window and a manufacturer’s warranty to protect the purchase of your lawn tractor battery.

Rest assured that you’re getting a high-quality battery, no matter which one you buy.
