Why Should You Test Your Car's Battery?

The best Arizona and most reliable car batteries for automobiles in the desert southwest of Arizona.

Did you know 50-70% of all warranty-returned batteries are simply discharged? They are still good batteries. Then why do people think they need replacement?

My dad, a long-time shop owner, always told me that battery testing is not rocket science. But, if it is not conducted correctly, it can cost a lot of people time and money. Dad was right! Let's take a look. If your battery's engine won't turn over, but it starts immediately with a jump, it must be the battery, right?

There are a number of tests needed to run on this vehicle before it's determined the battery is not working properly. The following systems could also be the likely culprit for battery failure:

  • Starting system
  • Charging system
  • Key-off drain (parasitic draw)
  • Voltage drops
  • Loose cables, connections
  • Belt or belts
  • Safety switches
  • Computer codes

A battery test is a great place to start to determine if you need a new battery. The first step is a visual check for corrosion, container cracking or swelling, or loose connections, followed by a check on the battery's age.

Testing the battery with a battery analyzer is key to ensuring that other tests conducted offer good information. If the battery is discharged, it can negatively affect the outcome of the charging, starting, voltage drop and key-off drain testing. There are two primary ways to accurately evaluate a battery's immediate electrical performance: Conductance and load testing. This information will let you know if it's really your battery or something else on your vehicle that needs inspection or testing.
