Signs You Need A New Battery

If you're still wondering when you should replace your batteries, here are some signs you should look out for;

  • Loses charge very fast
  • Corroded terminals
  • Starts very slow
  • Wear and tear
  • Cracked case
  • Interlock issues

What Do You Need To Consider Before Buying the Best Lawn Mower Battery?

1. Battery Capacity

The battery capacity indicated in an AH (Amp Hour) rating should never be ignored when choosing a lawn tractor battery. Ideally, the higher the AH rating, the better the capacity of the battery. Before picking a battery capacity, it is important to know how much power the mower or tractor needs. If you don't, you can always do a search online to find out the requirements of your tractor.

2. Voltage

Voltage indicates the current flow in the batter and is used to determine the performance of the battery. In most cases, the ideal voltage of lawn mowers is 12 volts. However, with some models, the 6-volt battery is good enough, but if you're hoping for high performance, you can opt for special batteries that have 36 to 40 volts.

3. Cold Cranking Amps (CCA)

The CCA rating indicates the quantity that a mower can generate in 30 seconds, at 0°F and without going below 7.2 V. Generally, a higher rating would mean that the battery is capable of giving more power even when temperatures are low.

On the other hand, a lower CCA rating implies that it may be challenging to start the battery, especially in colder months. However, batteries with high CCA ratings tend to be pricier than those with lower ratings. Paying extra money for a higher CCA rating may not be necessary if you live in an area with a warm climate.

4. Material and Construction

While the construction quality depends on the battery manufacturer, you need to buy a battery that is made from durable materials for better longevity and performance. This is because a battery tends to pass through a lot from being content with shocks and vibrations as well as bumpy and uneven surfaces.

The material plays a huge role when it comes to construction quality, especially if you need to use the mower in cold weather. The heavy-duty and durable casing protects the internal components of the battery and reduces any chances of spillage. In addition, the outer casing should be made of high-quality materials like heavy-duty aluminum or metal plates for prolonged use.

Batteries that have lead plates need to be avoided because they tend to lose charge, which causes faster corrosion of the components in the battery. Nowadays, batteries have calcium plates that self-discharge, have no corrosion issues, and are less prone to vibration and vibrations.

If you're hoping to avoid spillages when the battery turns over, then you should consider gell cell batteries and absorbed glass mat technology. While batteries with high-quality construction will cost more, it is always the best lawn mower battery because it is less prone to damages.

5. Compatibility

The compatibility of the tractor compartment and your new battery is going to help you know if the perfect for you. If your new lawn mower battery is too small to fit in the mower's battery compartment, you might experience some overheating. When it's too big, it can restrict proper airflow in the compartment.

The height, width, and positioning of the battery compartment vary from one lawn tractor manufacturer to another. Therefore, it is also important to ensure that the connectors match the compartment thickness. Remember, if you force a battery into the compartment, it might cause irreparable damage.

6. Terminal Size

Another factor you need to consider is the terminal size since the length of the battery cables may impact the fitting. Generally, batteries are categorized into different groups based on their sizes and voltage. For example, the U1 group batteries are 8.3 inches long by 5.1 inches wide by 7.25 inches high. They have the positive terminals on the left side, while the U1R batteries have them on the right. Ensure you check the terminal position of the old battery before getting a new one.

7. Maintenance

While some models might be high maintenance, good-quality batteries have minimal to no maintenance. However, it would help if you kept an eye on the batteries when they sit for too long, especially during colder seasons. Here are some maintenance tips;

  • Storage- During the colder months, remove the batteries and park the lawn tractor where it is not very cold.
  • Follow a regular charging cycle to prolong the battery life
  • Change the riding lawn mower battery when it doesn't start or charge fast
  • Consider a battery that comes with a high reserve capacity which is the ability of the battery to function on its own.

8. Weather Resistance

A riding lawn and garden tractors tend to be exposed to harsh weather conditions since they are mostly used for outdoor activities. As a result, choose a battery that can withstand temperature changes and won't be affected by extreme weather conditions.

Frequently Asked Questions (FAQs) on Lawn Tractor Batteries

1. Can you recharge a dead lawn mower battery?

Yes, you can always recharge a dead lawn mower battery by connecting it to its charger. If you're unsure about the volt amount to set for your charge, you should consider 12 volts, which is the standard. However, if your batteries don't charge up after some time, then replacing batteries is recommended.

2. How long does a lawn mower battery last?

The durability of the batteries is dependent on how much you use them and the type of battery you choose. Many manufacturers claim that the life of the battery is based on the hours of usage. For example, some riding lawn mowers can last for three years, while others can go up to 10 years. Generally, most batteries will be recharged about 500 times before the need for battery replacement arises.
