How Long Does A Riding Lawn Mower Battery Last?
No matter how well you maintain them, batteries can only last so long – their average lifespan is around three to four years.
Of course, you can always prolong their duration with regular charging, cleaning, and ensuring the terminal connections are tight enough.
But, eventually, the time for refreshment will come.
How to Charge My Lawn Tractor Battery?
Any appliance powered by a battery must be charged periodically to function smoothly.
When it comes to the battery in your riding lawn mower, it’s essential to charge it at the beginning of summer because it could’ve weakened over the winter if you hadn’t disconnected the cables before storing it away.
Use a crescent wrench or pliers, but avoid touching the terminals with bare hands or bridging between them with the tool to prevent damage and injury.
Charge in a well-ventilated area.
Check the battery’s voltage and use a suitable charger.
Connect the charger cables to the battery, with the red positive cable going into the + symbol and the black negative cable going into the – symbol.
Then, plug the charger into the outlet.
Wait 4 to 6 hours for it to fully charge. Monitor the process. Unplug it once it’s full. Remove the black cable first and then the red one.
Reconnect the battery to the tractor.
Which Factors to Consider While Buying?
To choose the best riding lawn battery for your machine, consider these features first:
- The voltage
The ideal voltage for any type of lawn tractor is considered to be 12V. For heavier usage, you can opt for special batteries with a voltage of 36V or 40V.
Those with an 80s model would do fine with a 6V battery.
- The capacity
This capacity is represented in the AH rating.
One good rule of thumb to consider is that the higher the AH, the better its capacity.
If you don’t know how much power your riding lawn mower needs, you can consult the customer service of the seller.
- The construction material
The quality of the battery also depends on the quality of its construction.
To ensure your battery performs well and lasts long, opt for one made of high-quality materials.
Namely, since this battery will undergo a lot of stress during its lifetime, including shocks, vibrations, and exposure to bumpy surfaces, it needs to be strong enough to withstand it.
And, its construction also plays a role if you need to use it in cold weather.
When it’s inside a tough casing, its components are protected, and the risk of spillage is minimized.
The casing should be made of metal plates or strong aluminum to withstand prolonged use.
Moreover, since batteries have a limited quantity of liquid acid, it’s essential to opt for gel cell and absorbed glass (AGM) ones to prevent spillage when the vehicle is turned over.
Although ones made with plastic are cheaper, they’re not as good as others made with stronger materials.
- The CCA rating
This rating, known as the Cold Cranking Amp, is calculated by measuring the number of amps that the battery delivers in 30 seconds at 0 degrees Fahrenheit.
The higher this rating is, the better the performance, even in colder weather. The optimal rating is 315.
- The size
Batteries are available in several sizes. Based on size and voltage, they can be categorized into one of four types according to the Battery Council International.
When a battery is from the U1 group, its dimensions are typically 5.1 inches in length and 8.3 inches in height, with a height of 7.25 inches. This group, based on its positive terminal position, can be of two types: U1 and U1R.
The former has positive terminals on the left side, and the latter has them on the right. Although it may seem simple, the length of the battery cables influences the fitting.
Before choosing between a U1 and a UR1, check the terminal position of the old battery.
- Compartment compatibility
Before you click the ‘order’ button, make sure you check to see if it will fit in the compartment of the tractor.
If a battery that is too small is placed into a larger compartment, the compartment may overheat.
Consider the width and height; if they can’t be entirely compatible, ensure they fit as much as possible.
Forcing something into the compartment, such as a very large battery, may cause damage.
When Should I Replace My Riding Lawn Mower Battery?
It would be awesome if we had batteries that could last for several years, right? One thing’s for sure: when properly taken care of, things last.
And when you take good care of your battery, you may help prolong its lifespan.
Battery-wise, ensure you clean the terminals regularly, apply protective grease as needed, and store it in a dry location.
However, regardless of how good your maintenance is, they will eventually reach the end of their lifespan or experience a reduction in power.
If you notice some of the following signs, it may be high time to consider a new battery:
- Slow start
Even when it’s colder outside, most lawn tractor batteries are designed to start quickly.
If you need several attempts before it works, it may be a sign of a weakened battery, but it may also be related to the ignition or fuel system.
- Charge loss
A strong battery will keep the charge for a long.
And, it won’t need to be recharged that often.
Therefore, if the battery has recently required more charging or if it drains quickly, it may be time for a replacement.
- The case is cracked
Batteries come with high-quality cases that keep the electrolytes safe and are securely fastened to prevent spills.
If you notice leaks, check for any cracks or loose joints. If you don’t replace the battery, the spillage may end up corroding the metal.
- It’s worn out
If you inspect the battery, one or two quick looks are enough to see if it has been through a lot or not.
If it’s worn off, it will have thinner terminals, an old-looking case, and it will perform averagely.
- The battery has passed its warranty
Most batteries have a 3-year warranty, but yours is still in the tractor?
This is a sign to take action, not wait for problems to start arising, but replace it with a new one as soon as possible.
How to Change the Battery on a Riding Lawn Mower?
If it’s time to install a new battery in your riding lawn mower, ensure you do it correctly.
Follow these steps and you’re good to go:
- Safety first
Wear gloves and protective eyewear.
- Prep the mower
Perform the replacement on a flat surface in a well-lit area, and ensure it’s turned off.
- Locate the old battery
Lift the seat or hood of the tractor; you’ll find the battery in one of these two places. Use the appropriate wrench to loosen it.
- Take out the cables
Begin with the negative black cable; loosen it and slide it up and off the terminal. Put it aside and repeat with the red.
- Put away the old battery
Lift the old battery carefully and put it away.
- Clean the connectors
Use a baking soda and water solution to clean the connectors using a metal-bristled brush. This will help you eliminate rust and acidic buildup.
- Set up the new battery
Now, do everything you did before, but in reverse. Connect the positive red cable first, and then the negative black cable. Then, reattach any remaining straps.
- Test it
The mower should start right away. If it doesn’t, there may be another problem with the machine.
- Properly dispose of the old battery
Avoid throwing the battery into the trash- it’s illegal! This battery contains corrosive materials; it’s best to take it to a recycling plant or an auto center.
Is A Car Battery Suitable For A Riding Lawn Mower?
Both car and lawn tractor batteries work at 12V. Many people use batteries for their riding lawn mowers.
If you also want to do this, ensure the size is optimal and compatible.
However, the safest route is always using batteries designed for riding tractors.
How to Store the Battery In Winter?
When the weather is extreme, it can affect the battery’s longevity and reliability.
Therefore, avoid storing it in cold temperatures, as it can be damaged. The best option is to store it in a cool, dry area.
Remove the battery from the mower and place it in a trickle charger for an hour or two, or until the mowing season arrives.
