Lawn Tractor Battery Features and Considerations
Selecting the best lawn tractor battery for your mower can be a tough decision as there are many batteries to choose from. However, the trick lies in knowing the features to look for in a quality battery. Here are some factors you may need to consider before buying a new battery:
Type of Battery
This is the most important factor you should pay attention to while shopping for your battery. This is because there are various types of batteries you can use on your lawn mower. Here are the three types of batteries available:
- Lead-acid batteries
- Lithium-Ion batteries
- Nickel-Cadmium batteries
These batteries have areas of weakness as well as strong points. Keep in mind power output and longevity.
Lead Acid Batteries
Some lawn tractor batteries use lead-acid to work properly. However, these types of batteries need to follow a certain charging cycle to continue functioning efficiently in the long run. The lead-acid present in these batteries can crystallize if you fail to charge them for some time.
The charging capability tends to diminish when this happens. For this reason, we recommend having a maintenance charger to ensure the batteries are always charged even during the winter season.
These batteries usually have a higher power output and density. They also have little maintenance needs making them the preferred choice for a majority of users. However, the charge capacity of such lawn tractor batteries tends to deteriorate after a short period of use.
Nickel- Cadmium Batteries
These types of batteries are capable of handling strenuous conditions without disappointing you. The only major issue with these batteries is that you need to discharge them fully before recharging them.
If you fail to discharge them fully, they will end up losing their powered density. However, that will not reduce the time they can keep power. The good thing about them is that they are the cheapest models of the three options.
Type of Lawn
This is another crucial factor that should be given consideration. The size and type of your lawn will determine the choice of your lawn battery. Ideally, most lawn batteries can service a lawn that equals the size of a tennis court. Smaller lawns just don’t require nearly as large of a battery.
Lawns that are bigger than a tennis court may not work because batteries can last between 20 to 30 minutes between charges. It can only work if you have a spare battery that you can change mid-way while mowing your lawn.
It’s also perfect in places where it will not encounter taller grass or have to deal with a lot of undulations. In these cases the average life span and efficiency of the battery can be reduced. The type of lawn you have will determine whether or not the mower will require a spare battery. It will also determine the power output of the battery that you should buy.
Cold Cranking Amperes (CCA)
The output of the battery you intend to buy is another essential factor you shouldn’t overlook when choosing the battery. This is because engines differ. For instance, if the engine is big, you will find it difficult to turn. That said, lawn tractor battery output is measured in CCA.
A CCA rating refers to the current (output) your battery can deliver at zero degrees Fahrenheit in 30 seconds. It’s unlikely that you will be operating your mower in zero degree temperatures unless if you have a snow blower.
However, with the CCA rating, you will be able to know how sturdy your battery is and what to expect. Choosing a battery with higher CCA ratings will do the trick since a lower CCA current may fail to start the engine.
If the current succeed at starting your battery, the power consumed by the lawn tractor may overtax the battery’s construction and cause it to wear out quickly. To ensure your lawn tractor runs effectively, select a battery with the right power rating for your lawn mower.
The position of the terminal plays a significant role when it comes to installing the battery to your lawn tractor electrical system. Most lawn tractor batteries are categorized under Group U1and come in two varieties, U1R, and U1L, which refer to the terminal position.
Group U1R lawn tractor batteries have a positive terminal that is located near the right corner. On the other hand, the positive terminal of group U1L batteries is located near the left corner, on top of the battery.
While the internal construction of U1R and U1L is similar, the terminal position is crucial to the connection of the battery to the lawn mower. However, it’s important to note that installing U1R batteries in lawn mowers that require U1L batteries may not work.
Stretching the cables can lead to chafed insulation and cause problems associated with short-circuit. Besides, the cables may not be able to reach the terminals. A good option would be to opt for a battery that fits your lawn tractor.
Lawn tractor batteries are rated according to their physical size. Most batteries are Group U1. This means they are 7.25 inches high, 5.1 inches wide and 8.3 inches long. The dimensions are very crucial because the battery has to fit into the engine compartment and in the tray properly. This will enable the battery to connect to the cables.
To determine the size of your battery, check for this information in the included manual or online. If it’s not there, check the battery case or take a photo of the battery then send it to the customer care service of the manufacturer. They will give you all the necessary information concerning battery replacement.
The features and technical specifications of your battery should not be the only aspects to consider. This is because the construction of the battery will have an impact on its ability to withstand prolonged and extensive use. Batteries with metal plates submerged in sulfuric acid should be avoided as they tend to lose charge with time when not in use. They are also prone to corrosion.
Instead, we recommend batteries that contain calcium in their plates as a convenient solution. These batteries are highly durable and less prone to corrosion, impact damages, and vibrations. Additionally, they will not spill acid if they accidentally fall as they are equipped with Absorbed Glass Mat (AGM) technology. However, bear in mind that they are costly because they are robust and of high quality.
The voltage rating is the first thing you should start with because it’s the most important. Generally, most lawn tractors require 12 voltages batteries to run efficiently. However, there are other higher voltage batteries available like 36 voltages and 40 voltages.
It’s important to check whether the voltage of the battery you want to buy is compatible with your lawn tractor’s voltage requirements. So, before making the purchase, check the manufacturer’s description to confirm you are getting the right voltage for your lawn tractor.
Lawn mowers are designed for outdoor activities such as cutting and trimming plants. This makes the battery to be exposed to extreme weather conditions like low and high temperatures. The battery you choose should be resistant to temperature to prevent it from getting affected by cold or heat.
It should also give you optimum performance in extreme temperature conditions. Additionally, it should not heat up when subjected to continuous use for a long period.
Before investing in a battery, you should check whether it will fit properly in the battery compartment. For example, a bigger space can accommodate a larger battery. On the other hand, fitting a bigger battery in a compartment that is small will reduce the space. However, this can affect the flow of air around it.
It can also result in high temperatures and allow acid spills to reach other components of the lawn tractor. This could cause rust or corrosion. In case you want to fit batteries with higher capacities, consult an expert or follow the manufacturer’s recommendation.
Most people buy batteries without checking whether it is easy to maintain them. For some, as long the battery fits their budget and is the right size, it is perfect. However, you can easily damage your battery if you fail to follow the right procedure of maintenance. For instance, you can end up with a dead battery if it’s maintained by adding distilled water and you forget to do that.
If you tend to forget or are not a hands-on person, it’s advisable to go for sealed maintenance-free batteries. These types of batteries require no maintenance except charging and dusting them regularly.
A good lawn tractor battery should be one that you can mount in any position. However, for this to happen, the battery should be sealed completely to ensure there is no chance of acid spilling. The place to mount the battery differs for different lawn mowers. Check where this place is indicated on your mower.
Whenever you are handling batteries, you need to be careful with acid spillage. It can be harmful to you, the battery, and your lawn tractor. Opt for batteries that feature the AGM technology since it prevents the acid from leaking.
Having a good lawn tractor battery will help you maintain your lawn without experiencing any technical difficulties while mowing. The batteries on our list are quality SLA/AGM batteries and are spill and leak proof. They are also maintenance-free and mountable in any position. With this information, we hope you will be able to pick the right battery for your tractor and make mowing your yard an enjoyable experience.
