10 Best Riding Lawn Mower Batteries [Reviews & Buying Guide]

For your lawn mower to perform optimally, you need the best riding lawn mower battery. A quality battery optimizes its functioning but also lowers the frequency of battery replacement.

This eventually saves you time, money, and effort.

Before anything else, you should know that a lawnmower battery and a lawn tractor battery can’t be used interchangeably.

That is, the tractor ones can be placed on a mower, but never the other way around.

Although buying a battery may seem like something we should leave to a mechanic, it’s not that difficult to do if you know the right information.

And, we’re here to provide them; below, check the 10 best options currently, as well as some extra tips to make the purchase and replacement even easier!

How Long Does A Riding Lawn Mower Battery Last?

No matter your proper maintenance, batteries can only last so long-their average span is around three to four years.

Of course, you can always prolong their duration with regular charging, cleaning, and ensuring the terminal connections are tight enough.

But, eventually, the time for refreshment will come.

How to Charge My Lawn Tractor Battery?

Any appliance that’s powered by a battery has to be charged occasionally in order to function smoothly.

When it comes to the battery in your riding lawn mower, it’s essential to charge it at the beginning of summer because it could’ve weakened over the winter if you hadn’t disconnected the cables before storing it away.

Use a crescent wrench or pliers, but avoid touching the terminals with bare hands or bridge between them with the tool to prevent damage and injury.

Do the charging in a ventilated area.

Check the battery’s voltage and use a suitable charger.

Connect the charger cables with the battery (red positive cable goes into the + symbol and the black negative cable goes into the – symbol.)

Then, plug the charger into the outlet.

Wait for 4 to 6 hours before it gets fully charged. Monitor the process. Unplug it once it’s full. Remove the black cable first and then the red one.

Hook the battery back into the tractor.

Which Factors to Consider While Buying?

To choose the best riding lawn battery for your machine, consider these features first:

• The voltage

The ideal voltage for any type of lawn tractor is considered to be 12V. For heavier usage, you can opt for special batteries with 36V or 40V.

Those with an 80s model would do just fine with a 6V battery.

• The capacity

This capacity is represented in the AH rating.

One good rule of thumb to take into account is that the higher the AH, the better its capacity.

If you don’t know how much power your riding lawn mower needs, you can consult the customer service of the seller.

• The construction material

The quality of the battery also depends on its construction quality.

To ensure your battery has good performance and lasts long, buy one made of strong materials.

Namely, since this battery will go through a lot during its lifetime, including shocks, vibrations, and a lot of bumpy surfaces, it needs to be strong enough to last.

And, its construction also plays a role if you need to use it in cold weather.

When it’s inside a tough casing, its components are protected and the risk of spillage is brought to a minimum.

The casing should be made of metal plates or strong aluminum to withstand prolonged use.

Moreover, since batteries have a limited quantity of liquid acid, it’s essential to opt for the gel cell and absorbed glass (AGM) ones to prevent spillage when it turns over.

Although ones made with plastic are cheaper, they’re not as good as others made with stronger material.

• The CCA rating

This rating (Cold Cranking Amp) is calculated by the number of amps that the battery delivers per 30 seconds at 0 degrees F.

The higher this rating is, the better the performance, even when the weather is colder. The optimal rating is 315.

• The size

Batteries are available in several sizes. Based on size and voltage, they can be one of the four categories according to the Battery Council International.

When a battery is from the U1 group, its dimensions are usually 5.1 inches, 8.3 inches in length, and 7.25 inches in height. This group, based on the positive terminal position, can be of two types, that is, U1 and U1R.

The former has positive terminals on the left side and the latter has them on the right. Although it may seem simple, the length of the cables of the battery influences the fitting.

So, before you choose between a U1 or a UR1, check the terminal position of the old battery.

• Compartment compatibility

Before you click the ‘order’ button, make sure you check to see if it will fit in the compartment of the tractor.

If a too-small battery is placed into a larger compartment, the compartment may overheat.

Consider the width and height-if they can’t be entirely compatible, make sure they fit as much as possible.

Forcing something into the compartment (a very large battery), may cause damage.

When to Change My Riding Lawn Mower Battery?

It would be awesome if we had batteries that could last for several years, right?-One thing’s for sure, when properly taken care of, things last.

And, when you take good care of your battery, you may help prolong its lifespan.

Battery-wise, make sure you clean the terminals, regularly apply protective grease, and store it where it’s dry.

However, regardless of how good your maintenance is, they will eventually reach their end or reduction in power.

If you notice some of the following signs, it may be high time to consider a new battery:

• Slow start

Even when it’s colder outside, most batteries for lawn tractors are made to start fast.

If you need several tries before it does, it may be a signal of a weakened battery, but it may also be related to the ignition or fuel.

• Charge loss

A strong battery will keep the charge for a long.

And, it won’t need to be recharged that often.

Therefore, if the battery has recently been requiring more charging or if it drains fast, it may be time for a replacement.

• The case is cracked

Batteries come with quality cases that keep the electrolytes safe and are fixed tightly to prevent spilling.

If you notice leaks, check out for any cracks or looser joints. If you don’t replace the battery, the spillage may end up eating the metal and cause corrosion.

• It’s worn out

If you inspect the battery, one or two looks are enough to see if it’s been through a lot or not.

If it’s worn off, it will have thinner terminals, an old-looking case, and it will perform averagely.

• The battery has passed its warranty

Most batteries have a 3-year warranty, but yours is still in the tractor?

This is a sign to do something-don’t wait for the problems to start arising, but replace it with a new one ASAP.

How to Change the Riding Lawn Mower Battery?

If it’s time for setting up a new battery in your riding lawn mower, make sure you do it the right way.

Follow these steps and you’re good to go:

• Safety first

Wear gloves and protective eyewear.

• Prep the mower

Do the replacement on a flat surface, well-lit area, and make sure it’s turned off.

• Locate the old battery

Lift the seat or hood of the tractor; you’ll find the battery in one of these two places. Use the appropriate wrench to loosen it.

• Take out the cables

Begin with the negative black cable; loosen it and slide it up and off the terminal. Put it aside and repeat with the red.

• Put away the old battery

Lift the old battery carefully and put it away.

• Clean the connectors

Use a baking soda and water solution to clean the connectors using a metal-bristled brush. This will help you eliminate rust and acidic buildup.

• Set up the new battery

Now, do everything you did before, but in reverse. Connect the positive red cable first and then the negative black. Then, reattach any remaining straps.

• Test it

The mower should start right away. If it doesn’t, there may be another problem with the machine.

• Properly dispose of the old battery

Avoid throwing the battery into the trash-it’s illegal! This battery is full of corrosive materials; it’s best to take it to a recycling plant or an auto center.

Is A Car Battery Suitable For A Riding Lawn Mower?

Both car and lawn tractor batteries work at 12V. And, many people use batteries for cars in their riding lawn mowers.

If you also want to do this, ensure the size is optimal and compatible.

However, the safest route is always using batteries designed for riding tractors.

How to Store the Battery In Winter?

When the weather is extreme, it can affect the battery’s longevity and reliability.

Therefore, avoid storing it in cold temperatures because it can get damaged. The best option is to keep it in a cool and dry area.

Remove the battery from the mower and put it into a trickle charger for an hour or two weeks until the mowing season arrives.
