How To Pick The Right Lawn Mower Battery?

Riding lawn mowers feature electric starting. It is a feature that makes it easier to start their larger engines, unlike push lawn mowers which are pull-started. Like in automobiles, this riding lawn mower battery makes it possible for the mower to start. If the battery is put to proper use and maintenance, it might last for over three years. It will even last longer in warmer climates. But, at some time, the battery will corrode or sulfate, and as a result, the output will gradually reduce over time. As a result, the ability to keep the charge and start the mower will be reduced. That means the battery needs to be replaced.

Selecting the batteries for riding mowers is a tough decision. There are many models to choose from in the market today. Determining the one that works ideally can be a little daunting and overwhelming. But the trick always lies in narrowing down to the specific requirements of the lawn tractor and the lawn itself. Here are some of the factors that need to be considered before purchasing a new battery:

  • The position of the terminal

The terminal position is essential for installing the battery to the lawnmower tractor’s electrical system. For example, group U1L riding mower batteries have their positive terminal on top of the storm, near the left corner. On the other hand, group U1R batteries have their positive terminals located near the right corner.

Installing a U1R battery in a riding lawn mower that requires a U1L battery may not work. The cables might not reach the terminals. Besides, stretching the wires could result in chafed insulation. As a result, it might cause a dangerous short-circuit problem. Go for a battery that only fits into the requirement of your mower.

  • Cranking Amps

All engines are not the same. The larger the engine, the harder it is to turn it. That makes the output of the battery another very critical factor you need to consider when selecting the battery. The riding mower battery output is measured in CCA (cold-cranking amps). This measure describes the work (current) the battery can deliver in 30 seconds at 0 degrees.

Choosing a storm with the optimum CCA will do the trick. Otherwise, a lower CCA output may not start the engine at all. And, if it succeeds at creating the battery, the power sucked by the equipment will overtax the battery’s construction. As a result, it will wear out faster. To keep the machine running effectively, the user needs to choose a battery with your lawnmower’s proper power rating.

  • The type of garden/lawn

The type and size of the garden will affect the choice of the lawn battery. Typically, most batteries for riding mowers can only service a lawn that is the size of a tennis court. Since the battery lasts between 20-30 minutes between charges, anything larger than a tennis court might not work unless there is a spare battery that would be swapped out mid-way through cutting the grass.

Again, it is ideal in areas where it would not have to deal with taller grass or many undulations that reduce the battery’s efficiency and reduce the battery’s average life span. The type of garden determines the battery’s output that needs to be purchased. It also determines whether or not the mower would need a spare battery.

  • Types of battery

There are different types of batteries that can be used on lawnmowers. Some prefer lead-acid batteries. But most of the time, the battle is always between Lithium-Ion and Nickel-Cadmium batteries. These types have their strong points and areas of weakness, especially regarding longevity and power output.

For example, NiCd batteries are cheaper but can also handle strenuous conditions without failing. The only challenge with these batteries is that they need to be fully discharged before recharging. If they are not fully discharged, they lose their powered density, which won’t reduce the time they can hold power.

On the other hand, Li-Ion batteries usually have a significantly higher power density and output. Besides, these batteries have little maintenance needs. Unfortunately, such a lawn tractor’s battery charge capacity deteriorates after a few years. The choice of the batteries will depend on the specific needs and the user preferences for power out.
