Reasons to Have Cat Spare Parts On-Hand for Your Heavy Equipment: Batteries

Imagining a world without batteries is like imagining a world without technology. While batteries began somewhat inauspiciously, today Americans buy more than three billion dry-cell batteries a year that power everything from our kids’ toys and watches to computers, cell phones, and our vehicles. It’s safe to say we’d have a lot less gadgets and not as rich of a life without batteries.

Fundamentally, batteries store chemical energy that is then converted into electrical energy when you “turn them on,” or “use them.” The electrons in a battery flow through a conductive path such as a wire, which generates an electrical current that is then used to do work. These electrons are forced to flow through the wire, which then does work along the way, such as light a light bulb. When you plug in your cell phone, for example, to recharge it, the direction of the flow of electrons along this wire is reversed, resulting in an electrical charge being stored until called upon for use.

Batteries have been around a long time and were the primary source of power before electricity. In fact, it is believed an ancient clay pot found in Baghdad was the first battery that we know of, and it is over 2,000 years old. However, the principles of why batteries work weren’t soundly explored until 1780 when an Italian biologist, Luigi Galvani, discovered that when two types of metals came into contact with a dead frog’s leg, an electrical current ran between them that then caused the dead frog’s legs to twitch. 

The first battery was created by another Italian scientist, Alessandro Volta, in 1799 when he stacked layers of zinc, a brine-soaked cloth, and silver. Dry batteries were pioneered in 1868 by a Frenchman named Georges Leclanche and perfected by Carl Gassner in 1888. Today’s batteries first appeared in 1899 when the nickel-cadmium battery was invented that could store energy, and Thomas Edison created the nickel-iron battery in 1900. Alkaline batteries were developed in 1967, and lithium batteries appeared in 1971 with further refinements throughout the years.


  • Prevent costly breakdowns. Any time your heavy equipment goes down, the repercussions may extend the entire length of your job site, depending on what you are actually doing and how integral your heavy equipment is. By having a spare Cat battery, you can ensure that your breakdown is a minor hiccup versus a full-blown cold.
  • Saves time. Usually your battery will go down when you need it. This is because you don’t know that your battery is on the blitz until you go to start your heavy equipment. This can delay all of your operations as you work to find a Cat replacement battery sooner rather than later.
  • Saves money. From having to pay an employee to visit the nearest Cat parts store to having employees standing around waiting for the new battery to arrive, you can sometimes see the dollar signs scroll by. With a spare Cat battery on-hand, you’ll save money in the long run.
  • Saves you frustrations. Many people underestimate the toll that stress and frustrations can take on their health, their attitude, and their overall job performance. Some people get extremely upset when things don’t go as planned. If you are one of those, it’s most definitely a good idea to invest in a spare Cat battery and save your health and well-being.
