Lawn tractor battery size. Best Lawn Tractor Batteries: Enough Power for the Whole Lawn

How To Choose The Best Lawn Tractor Battery

Lawn tractors make easy work of maintaining your lawn grass, but what happens when the battery no longer works? Similarly, there are times when a single charge no longer lasts for the whole operation. Instead of immediately buying a brand new lawn tractor, you should consider looking for a good battery replacement. Here, we take a look at the best lawn tractor battery to buy in 2021.

​What Is A Lawn Tractor Battery?

We all know that a lawn tractor is capable of many tasks that help improve the quality of your property with ease. Still, we must also be aware of its parts. In particular, we should know more about the lawn tractor battery.

​Size and Voltage

​For one, lawn tractors use various batteries that differ in voltages. You cannot just buy any random lawn tractor battery and expect it to work with the tractor you have. Lawn tractor batteries do come in different sizes. An overloaded lawn tractor due to a wrong battery isn’t desirable. Thankfully, you only need to either browse the user manual or search for the relevant information of the tractor model online.

​Use of Lead Acid

​Lawn tractor batteries utilize lead acid to function. Basically, the batteries need to follow a particular charge cycle in order for them to continue working properly in the long run. If you do not charge them for quite some time, the lead-acid contained in these batteries could crystallize. When this occurs, the charging capability is diminished. Thus, it’s wise to have a maintenance charger to keep the batteries charged even throughout winter.

​Here’s a video to help you know more about replacing a lawn tractor battery:

Maintenance and Use of Battery Water

Just like with any lawn care equipment, it’s important to practice proper maintenance of the battery. We’ll expound on this later on, but some general points include checking connections, cables, and terminals. They should be properly placed and cleaned to stop dust and other debris from affecting the batteries.

​Also, there are lawn tractor batteries that utilize battery water. These particular models need checking the battery water levels to ensure an optimal operation.

​When To Get A New Lawn Tractor Battery

Now that you know what a lawn tractor battery is, you must know when it’s the right time to get yourself a new one. The first sign is when the battery case begins to show cracks or have leakages. Second, you should get a new battery if the battery case has a bulge, which typically results from overheating.

​In addition, a battery with terminals that has damages and signs of extreme corrosion need to be replaced as soon as possible. A fourth reason is when the incorrect charger setting is used. Likewise, you should discontinue using the battery if it has a low electrolyte level. This occurs when air gets into the internal plates and it could lead to sulfation. Of course, an obvious reason to replace the battery is when the battery ceases to have a charge.

​How To Determine The Lawn Tractor Battery Size

If the information about the battery size isn’t readily available in the instruction manual or online, you can check it for yourself. In simple terms, the battery size can be identified through the measurement of volts and amps. Most lawn tractors need a 12-volt battery, but large models could need as many as 40 volts. Also, it’s important to be careful when handling the battery and to wash your hands afterward due to the sulfuric acid contained in it.

​First, you need to look at the upper section of the battery case. Search for the plastic caps. These can be actually unscrewed to give you a good view of the battery cells. Now, you must determine the total number of plastic caps. This total number should then be multiplied by two – the result is the battery voltage. To give an example, a battery with eight plastic caps has 16 volts. Furthermore, you should look at the battery case to get more information.

​A lot of lawn tractor batteries would have the voltage and the max current written there. The voltage would be simplified as “V” while the maximum current is shortened as “A” as it is also known as the amperage. If you still haven’t identified the size of the battery, you can take a picture of the battery. Just send this to the customer service of the battery manufacturer and they should provide you with the necessary information regarding battery replacement.

​Factors To Consider In Buying The Best Lawn Tractor Battery

Apart from knowing the battery size that is compatible with your lawn tractor, there are other factors that you need to be aware of before you get a replacement battery.

​Terminal Placement

​The positive terminal of a battery can be located either on the left side or the right side. You must know the terminal position required for your lawn tractor. The incorrect placement as you proceed to attach the cables could lead to damages both on the lawn tractor and on the replacement battery.

​Construction

Some lawn tractor batteries have metal plates while others use lead plates exposed to sulfuric acid. Back then, the use of these lead plates didn’t get enough support due to their corrosion and loss of charge. With the application of calcium, however, these lead plates now have better tolerance for the aforementioned issues.

​CCA Rating

​CCA refers to the cold cranking ampere, which is something that lawn tractor batteries produce. Each battery has a CCA rating, which is identified through the measurement of the current created in 30 seconds when the temperature is at a mere zero degrees Fahrenheit. When the battery has a CCA rating, it means that it offers a good amount of battery and it will work well even under cold temperatures.

Things to Consider When Buying Lawn Tractor Batteries

Lawn tractor batteries aren’t too different from one another, which makes finding one relatively simple. But before you jump right into buying a new battery for your lawn tractor, you’ll want to make sure you get the right one. As you consider your options, you’ll want to keep a few things in mind.

Battery Size

When you’re shopping for a new lawn tractor battery, you definitely want to make sure you’re getting the right size. Buying a battery that’s too small may work, provided it has adequate power, but if you end up with a battery that’s too big, then it might not fit on your tractor.

Remember to measure your battery before you buy one, and factor in any clearance your battery might have if necessary.

Terminal Position

Just as matching the size of your old battery is important, make sure to take note of how the terminals are oriented. When accounting for the position of the terminals on your old battery, you’ll want to orient the battery so the terminals are closest to you (typically, tractor batteries also have print on the same side as the terminals).

There are technically a few ways that battery terminals can be oriented, but the most common orientations for lawn tractor batteries are right-hand positive (RHP) and left-hand positive (LHP).

Warranty Duration

While most batteries will last for at least a couple of years, issues can crop up at any time. That’s why you’ll want to make sure that you’re getting a battery that has an adequate warranty. Most batteries have a standard 1-year warranty, but some batteries, such as the CB CHROMEBATTERY YTX5L-BS iGel Lead Acid Battery, feature an even longer warranty.

Cold-Cranking Amps

Cold-cranking amps (CCA) are perhaps the most confusing aspect of lawn tractor batteries. Cold-cranking amps are the number of amps a battery can deliver at 0 degrees Fahrenheit, while also keeping a minimum voltage of 7.2 volts for a 30-second period.

But unless you plan to use your tractor in the winter as a plow, then you might wonder if the CCA rating of a battery matters for you? The truth is, it depends.

You see, some tractors specifically call for deep cycle batteries. But deep cycle batteries typically don’t have a CCR rating, which can be fine for smaller tractors that don’t have a particularly powerful engine.

Larger tractors (such as zero turn mowers,) on the other hand, may have a larger motor that requires more cranking power to get them started. This is where you’d want to find a battery with an adequate CCR rating. And of course, if your lawn tractor doubles as a snow plow in the winter, then you’re going to want a battery with a good CCR rating to handle the cold weather.

Voltage

Matching the voltage to your mower is another important factor when buying a lawn tractor battery. Fortunately, most lawn tractors require 12 volt batteries, which are plentiful. In fact, every battery on our list is a 12-volt battery, so you won’t have to worry about that.

Still, some lawn tractors – particularly older ones – may have different voltage requirements. Make sure that the battery you’re replacing has the same voltage as the battery you’re buying.

Battery Capacity

When buying batteries, going with a battery that has an adequate capacity for your needs is important. A battery with a higher capacity will last longer, and has the ability to take on heavier loads than a lower capacity battery.

So if your tractor requires a high-capacity battery, you’d probably want something like the Mighty Max Battery ML35-12 or the CB CHROMEBATTERY Deep Cycle Battery.

Now that you have an idea of what to look for in a lawn tractor battery, let’s take a look at the best lawn tractor batteries we’ve found.

Everything You Need to Know About Lawn Tractor Batteries

We’ve covered some important information to keep in mind while shopping for batteries. We’ve also gone through some of the best batteries we can find for your lawn tractor. Now let’s get into some tips for changing and maintaining the battery on your lawn tractor, as well as some commonly asked questions.

Changing Your Lawn Tractor Battery

When you finally find it’s time to replace the battery in your lawn tractor, you’ll want to do it right, so you don’t damage your tractor, your battery, or yourself. Fortunately, changing the battery is fairly simple. Here’s a quick how-to on changing the battery out.

• Safety first. Being prudent and wearing safety gear such as rubber gloves and safety glasses will help keep you safe in the rare event that a disastrous accident occurs.
• Start by disconnecting the old battery from the tractor. Make sure to disconnect the negative terminal first, as disconnecting the positive terminal first can create a safety hazard.
• Once you’ve disconnected the old battery, pull it out of your tractor.
• Now place the new battery in your tractor, making sure not to pinch any wires, and secure the battery with any mounting hardware your tractor comes with.
• Remove the caps from the new battery’s terminals, and make sure you correctly identify the positive and negative terminals (sometimes the caps may be incorrectly placed, so it’s better to examine the battery for the positive and negative symbols, rather than relying on the cap placement).
• Connect the positive terminal, and properly tighten it before continuing to avoid a nasty shock later.
• Now connect the negative terminal and tighten it.
• If your tractor has terminal covers, put the terminal covers over the terminals. Close the battery compartment lid, and you’re done!

Tips for Maintaining Your Lawn Tractor Battery

To ensure you’re getting the most out of your battery, you’ll want to make sure to maintain it properly. Here are a few ways you can help extend the life of your battery.

Keep the Battery Clean

When the terminals of the battery are corroded, it can cause power supply issues and even long-term damage. If you notice any corrosion on the terminals, you’ll want to clean and protect them from future corrosion.

Ensure Your Battery Stays Charged

Keeping your battery at optimal health means keeping it charged. Typically, your tractor’s alternator is responsible for keeping the battery charged. However, when a tractor sits unused for a long time, the battery will slowly discharge. Cold temperatures can also cause the battery to discharge.

If you’re planning to leave it sitting unused for a lengthy period, such as through winter, you’ll want to disconnect your battery and store it somewhere that’s clean and dry. You’ll also want to connect it to a 12V float charger to keep the battery charged. This will prevent it from deeply discharging, which can lead to a shorter lifespan for non-deep cycle batteries.

You can also use a trickle charger. However, unlike a float charger, it won’t turn itself off when the battery is fully charged. That means that you’ll have to periodically connect and disconnect the charger to avoid overcharging the battery, which can also shorten its lifespan.

Lawn Tractor Battery FAQ

Will a Lawn Tractor Run Without a Battery?

No. A battery is required to provide a spark to turn your engine over when you start it.

But most lawn tractors utilize the battery for more than just cranking the engine. From headlights and onboard electronics to control mechanisms for more advanced features, your tractor’s battery plays an important role keeping the tractor functioning properly.

Can You Use a Car Battery in a Lawn Tractor?

Technically, yes. As long as they’re the same voltage, then it’s possible. However, there’s a couple of things that make this an implausible choice.

First, lawn tractor batteries are typically more durable than car batteries. This is due to the differences in how cars and tractors are used. Since lawn tractors may run across more bumps and changes in terrain, and don’t have comparable suspension systems to cars, tractor batteries are built to withstand a greater level of shock than a car battery.

Car batteries are also bigger than lawn tractor batteries. That means that you probably won’t be able to fit it on your tractor, or you’d have to get creative to make it work.

Can You Jump a Lawn Tractor With a Car?

As long as both batteries are the same voltage, then yes. However, there is one important caveat.

Jumping a car battery using another car is a fairly standard procedure – simply connect the cables between both cars to the same corresponding battery terminals. Jumping a lawn tractor with a car, on the other hand, is a little different.

Particularly, when connecting the negative cable to the mower, you want to connect the negative jumper to the metal frame of the mower, somewhere away from the fuel tank and battery, rather than to the negative post of the battery. This is because batteries generate hydrogen gas while charging, and a spark from the higher amperage of a car battery can cause an explosive reaction with the gas.

Using your car to jump start your tractor is fairly easy and safe, as long as you take the proper precautions. However, if you’re uncomfortable with the risks, we recommend you pick up a 12V battery charger instead.

How Long Does It Take to Charge a Dead Lawn Mower Battery?

Generally, the time it will take will depend on the amperage you set your charger to charge at. You’ll want to avoid charging the battery at an amperage higher than 10 amps, as this can cause damage to the battery. At a 10-amp charge rate, it should only take about an hour to fully charge a lawn tractor battery.

However, your battery may take longer to charge if you’re using your charger at a lower setting. Also, if after 8 hours of charging at a 10-amp setting, the battery still isn’t fully charged, your battery is likely dead and you’ll need to replace it.

When Should I Replace My Lawn Tractor Battery?

If you notice that your battery dies frequently, or won’t turn over your tractor’s engine, then it might be time to replace the battery. Keep in mind, however, that the battery might not be at fault here.

After you’ve properly cleaned any possible corrosion from the terminals to ensure a proper connection, you’ll want to pinpoint the issue to ensure it’s not a faulty alternator. You can test this, either by using a multimeter to read the voltage of the battery, or by connecting the battery to a charger and seeing if it will fully charge.

Can I Use a Battery With Higher Cold-Cranking Amps?

Yes you can. In fact, a battery with higher cold-cranking amps than your old battery can improve its ability to start in cold temperatures. This makes having a battery with a high CCA rating especially desirable if your tractor doubles as a snow plow.

Just keep in mind that higher CCA ratings usually correlate with battery size. That means you’ll want to make sure the beefier battery you’re considering will fit.

Finishing Up

If you’ve made it this far, congratulations! You’re practically an expert on lawn tractor batteries. Now that you know what to look for, and how to safely change and maintain your battery for optimal performance and longevity, all that’s left for you to do is get out there and mow your lawn.

How Many Amps is a Lawn Mower Battery?

However well you look after a lawn mower, eventually, after a certain amount of use, some parts start to fail, and some parts need to be replaced. If you have a riding lawn mower a walk-behind model or perhaps a self-propelled lawn mower it may incorporate a battery, meaning you don’t need to start it up by yanking a cord. However, the downside is that the battery is another component you will eventually need to change.

If you have to fit a new battery, you need to make sure the one you buy is compatible with your mower – so here we look at the question, how many amps is a lawn mower battery?

If you need to know how to change a lawn mower battery, here’s a video that will show you.

What does amps mean? And what about volts?

Mower batteries are rated either by amps or volts – or usually, by both. If the reason you want to know how many amps a lawn mower battery produces is that you need to buy a new one, it is worth taking a moment to understand what each of these means.

Amps and volts are two of the units we use to measure electricity – however, they are not the same.

Amps is the unit used to measure electrical current while volts is the unit used to measure voltage – or the difference in electrical potential. This might seem rather abstract, but there is a simple analogy that makes it easy to understand.

If you think of water moving through a pipe, the speed at which it moves is the equivalent to electrical current – this is what is measured in amps. Having more current is the same as having water that moves faster through the pipe.

The pressure that forces the water through the pipe is the equivalent to electrical voltage – this is what is measured in volts. Having a higher voltage is the equivalent of having a stronger water pump that pushes the water through the pipe.

For our purposes here, we don’t need to go any deeper into the science. All you really need to understand is that if you are looking for a new battery for a mower, you need to make sure that both the current and the voltage are compatible with your machine.

Choosing a battery

One thing that makes all this a little simpler is that nowadays, most riding mower batteries are rated at 12V – but in any case, you should make sure the battery’s voltage is compatible with your mower.

However, when choosing a new battery, there are two other things you need to pay attention to. The first is terminal position, and the second is Cold Cranking Amps (or CCA for short).

Terminal position

Terminal position refers to the physical configuration of the battery, and mower batteries come as either U1L or U1R.

As you may guess, the L and the R stand for Left and Right respectively. A U1L battery has the positive terminal near the left corner while a U1R battery has it near the right corner.

With this in mind, it is clear that you need to choose the right version to ensure that it will fit into your mower.

Cold Cranking Amps

When it comes to amps, the thing to pay attention to is Cold Cranking Amps. Since mower batteries are not used to provide a constant current but are there rather to deliver a powerful burst of current to get the engine started, this is the important number to take into account.

What this refers to is the current a battery can produce for a period of 30 seconds at a temperature of 0°F.

The reason this is important is that larger engines require more current to get them going. If you install a battery that can’t produce a powerful enough burst of current, at best, it will have to work extra hard to start your engine and will have a much shorter useful life.

At worst, a battery with a CCA rating that is too low won’t be able to start your engine at all.

How to choose the right battery

As we have mentioned, batteries have several different ratings. If you are replacing an old lawn mower battery, you need to check all of these and not just amps.

For this reason, if you are looking to replace a lawn mower battery, simply asking about the amp rating is probably the wrong question – you need to look at voltage, CCA and terminal position too.

The best way to do this is to check the user manual that came with your mower. If you don’t have it and this is the first time you are changing the battery, you can also look at the old battery – the voltage and the CCA should be written on it.

Once you have these details, you know what specifications to look for on the new battery you need to by. If you can’t find the specifications written on the battery, you might need to check with the manufacturer.

Incidentally, we mentioned above that it is important to install a battery with a high enough CCA rating to start your engine – however, don’t be tempted to go for one that is much higher than you need either.

If you install a battery with a higher rating than you need, it won’t damage your engine – but nor will it provide you with any benefit. It will probably just cost you extra money you don’t need to spend.

Amps in a battery-powered mower

You may also see an electric cordless mower that displays a number of amps, but this is something different.

This doesn’t refer to cold cranking amps since these mowers don’t have gas-powered engines. Rather, this is the amount of current the battery delivers to power the engine.

If this is the question you are asking, the answer is simple. Most modern battery-powered lawn mowers have 12amp engines – which means 12 amps of current is delivered constantly to drive the engine. This is sufficient for most home users.

Understand what “amps” means – and understand why you need to know

We all use electrical appliances and tools every day, but many people don’t understand the difference between amps, volts and watts. If you want to know how many amps is a lawn mower battery, the chances are, it’s because you need to buy a replacement. If this is the case, the number you should be looking at is Cold Crank Amps, and knowing this will help you find a compatible battery for your mower.
