What You Should Know About Your Lawn Tractor Battery

Best Lawn Tractor Battery

Our team has gathered everything you need to know about lawn tractor batteries in one place. First and foremost, we need to start with a definition, after all, we need to know exactly what we are dealing with, right?!

You need to think of the battery as the heart of your machine. Just like in the human body, if your lawn tractor or mower doesn’t have a heart, it can’t start working. Everything in this world needs a power source and for a mower or a lawn tractor, the battery plays this role.

If your goal is a perfect lawn, you definitely need a reliable lawn mower. That said, it is only logical that you also need a powerful, high-quality battery that will get the job done perfectly. After all, nobody wants to spend all of his or her time in the garage doing maintenance. Unfortunately, you can’t get away only with that. If you truly want the perfect lawn, things such as the good quality landscape edging, good brush cutter blades and so on, are also necessary.

So, what are the things you need to consider when you choose a lawn tractor battery?! They are not so many, but they are all important! Features such as voltage, terminal position, size, and construction are just a few of the factors playing role in the quality of the unit. Let’s take a thorough look at them in the next section of our buying guide.

Factors To Consider Before Buying A Lawn Tractor Battery

  • Voltage

This is surely the first thing you need to start with as it is probably the most important. The voltage rating of a battery is of huge importance. It shows us how much current can flow through the battery at a given time. When it is a lawn tractor battery that we talk about, the normal voltage is somewhere around 12 volts. There are special batteries, though, that have a higher voltage – as much as 40 volts and more! So, it is important to know if the voltage of the battery you have in minds suits your lawn tractor’s volt requirements.

  • Size and Terminal Position

Each battery does not only have different voltage but also a different size. The Battery Council International differentiate different groups of batteries according to the size and the voltage. The general types of batteries are categorized under the U1 group and they are about 5.1 inches wide, 8.3 inches long, and 7.25 inches’ high. Depending on the position of their positive terminals there are two main types of these batteries- U1 and U1R. The first ones have their positive terminals on their left side while it is the opposite with the U1R ones. You may think that this difference is not so important, but bear in mind that the length of a mower’s battery cables can prevent fitting. So, to know what you should be looking for – a good u1r battery or simply a u1 one, is really important. Always check the terminal position of the battery you are going to buy and see if it matches the one of your old battery.

  • Construction

constructionIn general, metal plates submerged in a sulfuric acid solution is what the batteries are made of. The common batteries have plates made of lead impregnated with antimony. Usually, batteries with lead plates are not recommended. They tend to lose charge over time even if not in use. Another disadvantage is the fact that the antimony content of the plates can be the reason for faster corrosion of the battery components.

However, as technology develops, a lot of the newer and modern batteries contain calcium within their plates. This is a convenient solution of the self-discharge and corrosion problems. Not only that but calcium batteries are also less prone to vibration and impact damages.  If you want a battery that will not spill if it tips over you to need to look for absorbed glass mat and gel cell batteries. This is due to the fact that they limit the amount of liquid acid in the battery.

Keep in mind that they are more expensive since they are of higher quality.

  • Cold Cranking Amps

Don’t look so scared, this only sound so hard to understand. In reality, it is super simple. Batteries produce ‘cold cranking amps’ and they are rated in regard to the amount they can produce. Each battery can deliver a different current in 30 seconds at zero degrees Fahrenheit and that is exactly what the CCA rating measures. This is important because cold climate conditions play a huge role in how good a battery is. Put in a few words, that is what lawn mower battery cold cranking amps are. The higher the CCA value, the more power the battery has. Therefore, if you live in a cold area, you can see how reliable the battery will be under cold climate conditions. We know that is unlikely to use your riding mower, for example, when the temperature is below zero but isn´t it nice to be sure that your machine can outstand everything, even the harsh climate.

  • Protection

It is probably unnecessary to say it, but our team wants you to think about everything that could be a problem when and after you buy yourself a lawn tractor battery. So the protection is something you need to think about. Keep in mind that you will need a place to store your battery, especially during the winter months. We will talk about that again when we start with the maintenance tips, still, this is a factor to consider when choosing your battery.

How To Know If A Lawn Tractor Battery Is Dead


Every person who maintains a lawn in the right way has a mower or a lawn tractor. If the machine you have is a battery-powered one, knowing when to change the lawn tractor battery is some pretty essential information. We all look for a good warranty on our lawn mower battery, still, sometimes even warranties are not a guarantee and bad things just happen.

  • Multimeter

After being stored for months during winter, your lawn mower or tractor battery can lose its charge. Same goes for when your battery is not used during long periods of drought. Most of the times charging the battery for a few hours fixes the problem. However, if that doesn’t work the first thing you need to do is testing it with a multimeter. That way you will determine if the battery is dead or if there is another part of the electrical system that has a problem. The battery is good when it has 12.7 DC volts or higher. That means that something else is causing the problem (starter interlock, for example). If the multimeter reads 11.5 volts or lower and you have already tried charging it and it didn’t work, than the battery is most likely sulfated and you will have to replace it.

  • Sulfation

This happens when the molecules in the electrolyte are already so discharged that they start to build upon the lead charging plates. When this happens, a decreased performance is always to be noticed. Eventually, the battery will quit during use or it will be impossible to charge it. So, if sulfation is your problem then you definitely need to change your lawn tractor battery.

  • Interlock Problems

If your battery is good but there is still some problem with your machine, then you probably have a problem with the interlock. Most starter interlock switches can be found under the seat or in the handle. If you have bent, corroded or in the worst case scenario, broken contacts the interlock will not enable the starter of the motor. The same goes if your wiring is damaged. We would advise you to use your DMM in order to trace the interlock circuit. That way you could repair it or adjust it.

When To Replace Your Battery

It is simple! If one of the things listed below describes your situation, then yes, you need to change your battery.

  • The battery case is leaking and is cracked.
  • There is bulging on your battery case.
  • You have damaged terminals.
  • You have corroded terminals.
  • There is a low electrolyte level.
  • The battery can’t be charged anymore – usually due to sulfation.

Lawn Tractor Battery Maintenance Tips

Lawn Tractor Battery

Maintaining your lawn is not an easy task. There are so many different products related to lawn maintenance, that you can get a headache just thinking about it.

Fortunately, keeping your lawn tractor battery in good shape is not that hard at all. There are a few things you need to do and if you do them correctly you should not be worried about a thing.

  • Keep your battery charged

If you want to extend the life of your lawn tractor battery it is a good idea to maintain it fully charged. That way you can get four to five years of life. This is because all lawn and garden batteries are flooded lead-acid batteries. If they don’t have a regular charge cycle they will start to crystallize and eventually lose their ability to stay charged. So, do not store the battery in a discharged state is a rule you need to remember!

  • Always keep your battery clean.

The same way you keep your garden and lawn in a good form, using the best brush cutter blade, fertilizer spreaders, and so many other gadgets, you have to keep your battery clean. The only thing you need is a wide brush or terminal cleaner and even heavy corrosion will not be a problem for you. Don’t forget that the terminals should be sealed with anti-corrosion gel if you want to prevent the build-up of corrosion.

  • Check the water inside the battery regularly.

Don’t forget to fill it. If your battery has removable caps, check the water levels and fill with distilled water every time when necessary.

  • Check your terminal connections on a regular basis.

You need to make sure they are tight because if that is not the case you can get a faulty battery. That is not everything, loose terminals can lead to low charge rates and corrosion.

  • Be careful with the wires.

If they are corroded, burned or frayed you need to change them ASAP.  Power leads are super important if you want your machine to work correctly.

  • Don’t force it

As we said, each battery has its own size and if the battery you have does not fit, don’t force it in as it may cause a problem later on.

Choosing A Lawn Tractor Battery Charger

As we have already mentioned, a typical modern lawn tractor will need a 12-volt battery. (the lawn tractor manufactured before 1980 are an exception. They use a 6-volt system and battery) The voltage of the battery being charged is the primary factor you have to consider when choosing your battery charger. Most chargers can handle a variety of voltages and may have a switch that will allow you to choose the voltage that suits your battery.

The battery charger may have different charging features and options. Trickle or fast-charging, a “jump” mode, even timed charging, are some of the examples. Our team recommends that you look for a 2-amp charge rate. It is the perfect option for lawn tractor battery recharging.

How To Charge My Lawn Tractor Battery

  • Remove the battery

You will probably need a pair of pliers or crescent wrench.

  • Choose an area that is well-ventilated
  • Connect the battery charger

The battery charger needs to be connected to the battery posts. The black clamp always attaches to the negative connector while the red clamp needs to be connected to the positive one. After you have done this, plug in the battery charger. Look at the charge meter or the LED light indicator. You can find out if the battery is fully charged in two ways. If you use the latter, you need to wait for a green light, and if you use the former, the battery is ready once it reads zero.

  • Unplug the charger
