Understanding Lawn Mower Batteries

Difference Between Traditional And Modern Lawn Mower Batteries

Lawn mowers have become a vital tool for maintaining a lush, green lawn. With the beginning of modern technology, traditional batteries have been replaced by more efficient modern batteries. Below are the key differences between these two types of batteries:

  • Traditional batteries: These batteries are lead-acid and need regular maintenance to ensure their longevity. They also need to be charged regularly to prevent them from dying out.
  • Modern batteries: Modern lawn mower batteries are usually lithium-ion and require minimal maintenance. These batteries charge quickly and last longer compared to traditional batteries.

Types Of Lawn Mower Batteries

There are two main types of batteries commonly used in lawn mowers:

  • Lead-acid batteries: These batteries are made up of lead plates and a sulfuric acid electrolyte. They are heavy and require regular maintenance to ensure they last.
  • Lithium-ion batteries: Lithium-ion batteries are lighter and require less maintenance compared to lead-acid batteries. They are also more expensive.
