Evaluating Lawn Mower Batteries

There are many different important factors to consider when it comes to evaluating lawn mower batteries. You will not want to have any of these features compromised or it could be detrimental to the value or life expectancy of your battery.

A lawnmower battery is evaluated on cold-cranking amps (CCA) to help you determine how powerful and valuable your battery will be. Overall, one of the most important features of your lawnmower battery to evaluate would be its size.

Size

You will have to pay close attention to the size of the battery if you want to choose one that will fit the dimensions of your lawnmower. Make sure the battery can rest within the tray and engine compartment while also connecting to the battery cables properly. In other words, the battery cannot be too big or too small.

Make sure that any replacement battery you buy in the future matches the dimensions of the old battery as well. This is important to avoid any possible size complications.

Construction

No matter what kind of construction your lawnmower battery has, you want to make sure to handle it properly and be certain that it will be durable and long lasting. Many lead acid batteries are constructed with high-quality materials and are quite easy to install. Lawnmower batteries that are properly constructed will not corrode or damage as easily as other less well-constructed batteries.

Safety

Always take extra precautions when you are handling lawnmower batteries. It is in your best interest to find one that is spill-proof to avoid potentially coming into contact with any hazardous chemicals.

Extreme temperatures and highly powerful vibrations can put tremendous pressure on the battery. So, it is important to make sure your battery does not freeze or overheat and is resistant to vibrations while it is running. Also, keep an eye out for any possible chance of a short circuit or any other electrical issue that may occur.

Mounting Position

An excellent, high-quality battery should be capable of being mounted in any position without worrying about leaking or its sustainability being compromised. It should hold up well in any kind of condition and fit into its designated area depending on your lawnmower.

Battery Life

You will want to have a lawnmower battery that is able to hold a long battery life, along with the necessary amount of voltage. Newer lawnmower models will most likely require a 12-volt battery in order to function. The higher the battery capacity, the better your lawnmower battery will be.

Effectiveness of the Battery

Your lawnmower will experience all types of terrain. Therefore, you will want to make sure that your battery will be able to effectively hold its ground with any type of terrain or vibrations that it will likely experience.

The newer models of lawnmower batteries are more likely capable of remaining sturdy throughout its lifespan as compared to older models. This is because they will be able to have a higher level of resistance against tough terrain and vibrations. You should ensure that you get the most effective battery available, so your lawnmower will be able to run smoothly.

Common Mistakes People Make When Choosing or Using Lawn Mower Batteries

There are many common mistakes that people can make when it comes to choosing or using their lawnmower batteries. Thankfully, there are ways to point out those mistakes. Some of the most common mistakes are:

• failing to check the size of the battery itself
• not knowing the difficulty level of maintenance
• forgetting to check the size of the battery compartment before buying the battery

A really important tip is to check the Cold Cranking Amps Rating (or the CCA). Bear in mind that the higher this rating is, the more cranking cycles it gives you. Choosing a battery with a low CCA can mean a much harder time starting up your lawn mower, especially in the colder seasons.

Alternatively, if you live in a hotter or tropical climate, you might want to skip buying one with a higher CCA since it will cost more unnecessarily.

Overall, be sure to also maintain your lawnmower and your battery so they can both continue to run as smooth as possible for as long as you need. Place it in a proper storage area to prevent it from receiving damage from different weather conditions.

You will want to find a battery that is easy for you to maintain so that you will not have any complications when you least expect it.

Always check the oil level in your lawnmower before using it. Also, make sure to regularly clean and replace the air filter so that your lawnmower will be able to keep running properly.

Proper Ways to Charge Your Battery

Always make sure that you take the proper safety precautions when you are ready to charge your lawnmower battery. Wear protective gear while handing the battery and charge it in an openly ventilated area to prevent any possible hazardous outcomes from happening.

To charge the battery, simply connect the necessary cables and set the charging power and allow it to charge over time. Another great tip is to charge it before its first use in the summer after having it stored all winter.

Conclusion

Overall, it’s vital that you know the important features of a lawnmower battery. This knowledge will help you keep it running smoothly. Additionally, remember to properly maintain the battery and your lawnmower. Failing to do so can result in the depletion of its usability and value, which can cut into your expenses if you need a replacement.
