Finding and buying the right replacement for your lawn tractor battery is a seemingly complicated process, as it’s difficult to tell the different models apart. But not to worry—that’s what our reviews are for. Find them below.
Mighty Max is a recognized manufacturer of quality batteries for not just lawn mowing machines, but for a number of other uses. This 35 AH model, in particular, is immensely popular, and it’s undoubtedly one of the best products on this list. Here's why we think so.
First of all, this thing is quite rugged. The housing is strong and durable and will offer some of the best performance you can expect in terms of the battery's ability to resist the shocks and vibrations your tractor might be subjected to.
Now here are some specs. It’s a 12-volt battery with a 35 AH rating, so it’s going to deliver standard operating power. It measures at 7.68 in x 5.16 in x 7.13 and weighs 23.15 pounds.
Its main appeal, though, lies in the SLA spill-proof battery which has a high discharge rate and can operate in many different temperatures.
The manufacturers have also integrated this battery with Absorbent Glass Mat (AGM) technology. The valve regulated design that comes with it makes it easy to use indoors without fear of leaking or other maintenance concerns. This battery's versatility means you typically don't have to worry about it underperforming in dry weather.
Something else many users love about this battery is how easy it is to install—it can be mounted in any position you requires. However, it's worth noting that your purchase won't come with mounting accessories or a wire harness.
We think this battery is definitely a good choice, especially for the price. However, as can be expected from most maintenance-free batteries, durability might be a concern.
This is another strong contender for the title of the finest lawn tractor battery on the market. Like the last one we saw, this one is also a 35 AH, 12-volt model; however, this battery boasts the privilege of having welding technology integrated into it—so concerns about heat, shocks, and vibration won't plague you.
The AGM technology used to construct the acid inside the battery makes it spill-proof and maintenance-free; there will be less chance of the battery dying despite the fact that there’s no need for maintenance. The battery itself is constructed with lead calcium alloy, so you can be assured about its durability.
And because the battery is sealed, you can mount it in any direction—a versatile battery really makes all the difference. Oh, and, this battery also comes with UL and OHSAS certifications, so you can rest easy about the safety of handling this battery.
Here are some specifications. This battery measures at 6.46”x 7.68”x 5. 12” and weighs 21.71 pounds (making it compatible with not only most lawn tractors but other applications as well). This battery uses a T3 terminal.
Oh, did we mention that this battery comes fully charged, right out of the box? The installation will be a breeze, and your tractor will be up and running in no time, with no filling or checking necessary. Some manufacturers really do put in the work to be thoughtful and considerate of their customers, and it shows.
Overall, this is a very good choice at a reasonable price but be wary of longevity concerns.
This next battery on the list is a great choice if you’re on a budget, or don’t require heavy-duty performance for your lawn tractor. Basically, if you don’t use your tractor very often, or if you don’t have a problem with replacing the battery relatively frequently, then this is a good one.
Being a sealed lead acid type with valve regulation, this battery is maintenance-free and won’t require any downtime on your part. It uses B1 terminals (internally threaded posts). What we love best about this battery, though, is how easy it is to install.
Despite its relatively high affordability, this battery, like any other respectable competing battery, utilizes absorbed glass mat technology. This gives it a wide temperature range, so you don’t have to worry about its performance being affected by unfavorable weather.
Here’s an idea about the specs of this thing. The overall dimensions are 3 1/32x”7 1/8”x6 7/16”—this makes for cozy fitment; however, be sure to measure your tractor’s battery compartment before purchasing this to ensure proper airflow.
Overall, this is a good choice at a low price if you’re not willing to put in a lot of effort to maintain your tractor battery. After the first time you recharge it, you’ll notice that it’ll make your tractor feel as if you just bought it. However, keeping the price in mind, note that overall durability may be low.
This high-performance battery is easily one of the products most worth your consideration on this list if you’re looking for a good battery on a budget. This battery is primarily for sporting purposes, but don’t worry; that actually makes it a very good fit for your lawn tractor.
What sets this battery apart is the gel electrolytes that are used in it. Called iGel batteries by the manufacturer, they are injected with gel electrolytes, which for you mean a totally maintenance-free battery.
This battery is a 12V one with a 4 AH capacity, and it runs at 48 watts. It measures at 4.21”x4.45”x2.6”, so it’s nice and compact. It weighs less than 4 pounds. This battery’s negative polar is positioned on the left, while its positive one is on the right.
Probably our favorite feature of this battery is its digital LED display screen, which is not something you see very often. It gives you a reading of the battery alternator voltage, and in the event of low voltage, you will be warned immediately.
The design and casing of this battery are constructed of surprisingly high-quality material, relative to the price—you can expect decent durability and longevity. There is also the added benefit of resistance to leaking or corrosion.
However, every great thing has a downside, and in this case, it would be the battery’s CCA—which is at 70. Sure enough, this is quite low, but if you take care not to store the battery in a place where it will be subjected to lower temperatures, you should be good to go.
The next one on the list is from a long-trusted, reliable manufacturer. That said, this option is considered best if you’re unwilling to shell out too much for a rechargeable battery. Furthermore, if you’re not too concerned about performance, this is a good choice, as it provides 18 AH operation.
So, first things first: this is a sealed lead-acid battery (it comes with nuts and bolts should you choose to take it apart), so it’s maintenance-free. The construction is quite rugged; the battery case is resistant to high shock impacts, heat, and chemicals due to its ABS plastic casing, which is nonconductive. The battery is also spill-proof.
This thing measures at 7.1” x3”x6.6”, and weighs at 12 pounds, so it’s quite heavy. However, it’s a decent fit for most applications. To make things better, the manufacturers send this battery already fully charged for your first use.
This battery also utilizes AGM technology. The internal acid is absorbed between the side plates, where it is immobilized by a fiberglass mat of fine construction. All of this makes it resistant to a wide range of temperatures and weather conditions, under the right storage settings.
Add to this the-valve regulated construction of the battery, and you get a product that enables safer and hassle-free operation. However, as you are enjoying a relatively lower price for this product, don’t be surprised in the event of its death.
This next battery is also from Chrome Battery, and they claim this is one of their more enhanced models. Especially at the price, you can usually get this battery at; we would definitely say this is a steal.
So, here’s what we like about this battery. The Sealed Lead Acid construction of this battery coupled with its AGM design (you already know what that is by now) ensure a standard resistance to corrosion and leaking.
Similar to other Chrome batteries, this one is also injected with gel electrolytes—the manufacturers call it iGel. It reduces maintenance by quite a bit (no more water checks!) and ensures relatively long life.
Also, like many other Chrome Battery models, something else to love about this one is the inbuilt LED display. Keeping up to date with the status of your battery is easier, as you can see battery alternator voltage levels at your own ease and convenience. Also, the digital display has an integrated intelligent chip to achieve this.
The terminals on this battery are heavy-duty, which augments its durability by making it that much more resistant to vibration and unforeseeable impacts from your tractor having to navigate difficult lawn terrain. The durable bridge welding on this thing also ensures greater vibration absorption.
And because the guys at Chrome Battery are so thoughtful, they ship this thing already charged—you can expect about 13V. All you have to do is connect your battery to your tractor to start it up; no need to charge it first. How convenient, right?
If you’re on a budget but are in need of a battery that will deliver moderate performance for your lawn tractor, then this is probably the one you’re looking for it. This sealed AGM battery, although meant primarily for motorcycles, works great for tractors at an unbelievable price.
But don’t let the low price throw you off—this guy is durable and reliable for up to at least 8-10 months. It owes this pleasantly surprising shelf life to its construction, which, like most other Chrome Battery batteries, is of lead-calcium alloy.
And just because this battery is cheap, doesn’t mean that the manufacturers skimped out on giving it the standard AGM treatment. So not only are you having to pay far less for shockingly adequate performance, but you also don’t have to worry about maintenance or the risk of leakage.
Plus, the manufacturers have made sure to provide you with a battery whose safety and consistency you can place your trust in. This battery, like others from the same manufacturer, has been tested extensively and can boast an OEM compatibility.
The terminal posts on this battery are patented, which makes it resistant to corrosion and ensures that it lasts you longer before you need to replace it. Moreover, this little guy is surprisingly resistant to vibration and shocks, with satisfactory conductivity capabilities.
However, if your tractor is a high-performing one that requires a strong battery, we would suggest skipping out on inexpensive batteries like this one. Although they perform well for their expected lifetime, such batteries can be overworked and burn out with a high-performing tractor model.
In our search for the best lawn tractor batteries on the market, this is one name that came up quite a few times, among other widely recognized names. This is particularly worth your consideration if you’re operating your lawn tractor in a colder climate. Here are a few of the reasons why.
If you know anything about lawn tractor batteries, then you'll know about something called the CCA, which is an important determiner of a battery’s performance in cold weather. Well, on this thing it is staggering—it's 315 CCA at a 35 AH capacity (at a 12 voltage operation).
So, if you're concerned about being able to start your tractor in the cold, you won't have to worry anymore. As for specs, this battery measures at 7.75 inches x 5.19 inches x 7.13 inches and weighs around 22.50 pounds.
Most of the batteries manufactured by this brand have a sturdy, rugged housing. The valve regulated construction makes the battery spill- and leak-proof, and coupled with the Absorbent Glass Mat technology, you can expect superior performance from this thing, even in dry weather.
We also appreciate how the spill-proof construction makes mounting this thing in any position so easy. However, despite the manufacturer's claims that this battery fits all John Deere tractor models, some users have reported otherwise. Thus, if you have a JD tractor and are looking for a replacement, first make sure the dimensions of this are suitable.
You probably already know that Mighty Max is a household name when it comes to batteries. But why is this one special?
Well, in our opinion, that would be because of its construction: of course, the acid in the battery has integrated AGM (as any respectable battery should!), but it’s also made of a pure virgin lead of premium quality.
Added to the pure lead, technology is the reduced internal resistance and enhanced plate compression. Together, these make for a longer life of powering your lawn tractor. Not only that; you can also expect quicker start-up times and improved deep cycling.
So, if durability is your main priority when it comes to your tractor battery, then this is definitely a good choice. Especially considering the moderate affordability of this thing, it’s quite a good deal.
Something else that’s great about this machine is the intuitive design that resists spills and leakage. It’s what accounts for this machine’s versatility when it comes to positioning and mounting, which are made that much more convenient.
And this machine’s cold-cranking ability is one of the best that you can find for the price: this Sealed Lead Acid battery operates at 12 volts and produces 200 CCA. As for other specs, this battery measures at 7.75 inches x 5.11 inches x 6.25 inches. The polarity is positive on the right and negative on the left.
So, if you’re looking for a decent, well-rounded battery for your lawn tractor, then look no further—we really don’t think you can go wrong with this one.
As we’ve already established, Mighty Max is undoubtedly one of the absolute best choices you can opt for when looking for a replacement battery for your lawn tractor. And so, we’ve saved one of the best for last.
Like most other batteries manufactured by Mighty Max, this one also features a state of the art, calcium-alloy grid that was designed for heavy-duty operations. You can always expect high-level performance and durability from this thing, no matter if you’re using it for your tractor or something else.
This 12-volt battery is constructed from Sealed Lead Acid and operates at 35AH. According to long-time users, this battery is rechargeable for up to 3 years, so if you buy this thing, you’ll be set for a long time. And considering its price, that’s basically a lot of money you’re saving.
The AGM integrated battery acid, together with the valve-regulated the design, also makes this thing capable of producing a high discharge rate and deep discharge recover. Yes, that also means that you can comfortably use this battery in indoor environments.
More importantly for you, if you’re living in a drier climate, this battery is able to operate in a myriad of weather conditions.
As a parting word, I’ll mention this: you’ll notice that the cons list for this product is the shortest and sparsest out of all of the products reviewed thus far. So, make of that what you will!
Probably one of the worst things that can happen on a lawn mowing day is discovering that your tractor won’t start. That’s usually when you know that your tractor battery is due for a replacement.
To help you find the right battery for your tractor, here is a rundown of the factors you have to take into consideration before purchasing one.
As you can imagine, this is probably the most pertinent factor in your evaluation of the right lawn tractor battery, as it is the ultimate determiner of the battery’s performance.
A lawn tractor battery’s voltage rating measures the amount of current that can flow through it at any given time. The standard voltage for batteries suited to lawn tractors is 12 volts, and in most cases, this will be good enough. If you have an older tractor model though (something from the ‘80s), you may need a 6-volt battery.
However, depending on the performance you need or expect from your tractor, you might need a battery with higher voltage ability—for those situations, there are special batteries that come at 36 or 40 volts.
Another concern in regards battery life is that of the AH specification. AH stands for "amp hour." The AH rating of a battery is an indication of the capacity of the battery. The higher the AH of the battery, the better.
Ultimately, no one better than you know how much power your tractor needs—if you don’t already know, figure it out. If you’re confused, you can always put in a call to your lawn tractor brand’s customer service hotline and inquire into the ideal battery voltage requirements for your owned model.
Batteries for lawn mowing machinery, including tractors, are rated according to their ability to produce “cold-cranking amps,” or CCA. The measurement of this is referred to as the CCA rating.
But what is the CCA? It’s a little complicated, so bear with me.
The CCA rating basically measures the amount of current your tractor’s battery can produce in 30 seconds at 0°F. The higher this rating is, the more power the battery can deliver in a quick burst at lower temperatures—otherwise known as the number of “cranking cycles” the battery can offer you.
The CCA rating can give you a basic idea of how strong your battery is, particularly on colder days. A battery with a low CCA rating is an indication that it will be harder to start in colder weather. Batteries with higher CCA ratings tend to cost more.
So, the bottom line is this: if you live in a colder climate, a battery with a higher CCA rating is necessary for you in order to derive optimal performance from your tractor. However, if you reside somewhere with warmer weather, then it would probably be unwise to pay extra for a battery with a higher CCA rating.
It can be confusing to figure out which batteries are of better construction than others. However, the quality of the construction material of the battery, of course, differs from one manufacturer to another. It’s important to choose a battery that is made from durable materials.
Your tractor’s battery will go through a lot in its lifetime, especially if your lawn is a bit difficult to navigate due to being bumpy or uneven. Your tractor will have to contend with shocks and vibrations. As you can guess, this isn't good news for the battery.
And if you’re operating the tractor in colder weather, then it goes without saying that a battery of better material is crucial. The heavy-duty casing will, of course, protect the internal components of the battery better, and reduce the chance of spillage.
It should be noted that a battery with stronger construction materials will cost you more than one made of cheaper material, such as plastic. However, the dangers of buying a battery with a weak outward casing manifest in the fading, cracking, melting, or warping that weak plastic are prone to, especially in higher temperatures.
Failing to take this factor into account is somehow a much more common mistake than it should be. However, it seems pretty obvious that you should always ensure that your battery will properly fit into the battery compartment of your tractor, right?
Many lawn tractor owners are thrown into confusion when they are faced with a tractor with an overheated battery compartment. However, that’s exactly what happens when you fit a too-small battery into a large compartment.
This is due to the fact that airflow inside the compartment is restricted. It’s not enough for your battery to just fit into the compartment; there should be a little extra space so that the battery is allowed to breathe.
There is also the risk you run of corrosion or rusting. Unbeknownst to many tractor owners, this actually owes itself to spillage in the mower due to inadequate space for the battery.
Note that the position, height, and width of the battery compartment can vary greatly amongst tractors, even from the same manufacturer.
Another thing to remember is that the connectors should match the thickness of the compartment. And make sure to read the manufacturer’s size and weight recommendations carefully or call a hotline if you’re still confused.
How long, and how efficiently, your battery will serve you, is greatly dependent on how much of a good job you’ve done in maintaining it.
Unfortunately, some batteries require higher maintenance and more frequently. On the other hand, some batteries don’t require as much effort.
For example, most batteries need to be topped up with distilled water every now and then, but then there are others with which if you do the same, will spill (as a result of excessive evaporation).
If you think that all of this sounds like too much for you, then you can consider getting a sealed battery. Such a battery will not require frequent maintenance and is likely to be cheaper; however, be warned that it’s likely to die more quickly.
The majority of riding lawn mowers will take U1 batteries, which are usually approximately 5.1 inches wide, 8.3 inches long and 7.25 inches high.
You may have guessed that the contender for this title is probably Mighty Max, but of course, you should decide for yourself.
On average, the best lawn tractor batteries will last you about 3 to 4 years. Even with proper storage, a longer shelf life than that is difficult to achieve.
The most probable cause is leaving the battery idle for too long, especially during dry seasons. Sulfation is another cause—this is when electrolyte molecules are discharged to the extent that they accumulate on the lead charging plates. Other culprits are a corroded or bent interlock, or damaged wiring.
Yes, some people do, as both car batteries and lawn tractor batteries operate at 12V. However, you will have to ensure that the size specifications are compatible. Furthermore, it’s recommended to buy tractor-specific batteries.
You probably already know that finding the best lawn tractor battery requires quite some research. However, if our reviews and buying guide are any indications, identifying the best products is actually simple.
On the whole, these are the things you need to look out for: voltage, cold-cranking ability, and durability. On that note, the Mighty Max Mighty Max ML-U1 12V seems like the best option.
However, if you’re not willing to spend so much, our top pick for you would be the Expert Power EXP12180 Lead Acid Battery. Not only is it affordable, but it’s also maintenance-free and weather-resistant.
As a parting word, though, we would recommend thinking of lawn tractor batteries as a long-term investment. As we have seen, the best ones will last you up to 4 years—a purchase like that will keep you at your ease for longer.
So be wise, and happy lawn mowing!
