What is the best battery for a lawn mower?

Choosing the right battery for your lawn mower is important for optimal mower performance and efficiency. There are several factors you’ll need to consider to ensure you get the right one. The knowledgeable staff at Northeast Battery can fill you in on the optimal battery for your mower’s needs.

Characteristics to Consider

When selecting batteries, there are a few different characteristics to keep in mind that help you choose the right one for your lawn mower. Two primary characteristics to think about are cranking amps and terminal position.

Terminal Position

Selecting the right terminal position is essential when considering batteries for your lawn mower. Most mowers take Group U1 batteries, which are regulated by the Battery Council International (BCI). These batteries are most commonly used in upright mowers.

This group further breaks down into two subcategories, which are:

• U1L
• U1R

The main difference between these two types of batteries is their terminal position. Group U1L mower batteries have a positive terminal in the left-hand corner towards the top of the battery. Group U1R batteries, on the other hand, have a positive terminal located on the upper right-hand side.

Batteries in both categories have a similar internal composition, but it’s important to get the right terminal connection for your mower to avoid problems. Installing the wrong type can cause electrical problems, including insulation damage and short circuits, which can be dangerous. If you need assistance deciding which type to get, the experts at Northeast Battery can help.

Cranking Amps

Optimal batteries for mowers should also be selected based on their cranking amps. Essentially, that means the power required to drive the mower’s engine. A battery’s power output is determined based on cold-cranking amps, or CCA for short. CCA indicates how must current batteries can produce at a temperature range of 0°F within 30 seconds without falling below 7.2V. Batteries with a CCA that’s too low might not start the mower’s engine, or they might cause the engine to work too hard due to an insufficient amount of power. Choosing batteries with the right power output to meet the engine’s requirements is critical to ensure the mower runs smoothly and its parts don’t wear out prematurely.
