Battery Basics

Corroded Battery

With all the gadgets we have on cars today, batteries are essential to meeting those needs. More than just cranking the engine, today’s batteries provide power to other electrical components even when the engine isn’t running.  And the battery acts as a voltage stabilizer for the entire electrical system.

Batteries (12 Volt) fall into two basic categories:

  • Flooded lead acid (FLA), which has been the standard for decades
  • Absorbent glass mat (AGM), a newer design that while more expensive generally lasts longer.

Both of these types of batteries have the same basic function yet they aren’t interchangeable.  Installing a standard 12-volt lead acid battery when a manufacturer requires an AGM can damage alternators or prevent electrical systems to function properly.

Be sure to check your owner’s manual when you are looking for a new battery.

While your car is in for service ask the mechanic to check:

  • Cleanliness of the terminals.
  • Mounting hardware and hold-downs. Batteries should be tightly secured in place. A bad battery hold-down cause battery failure or failure to start faithfully.
  • Know your battery warranty and be prepared to replace every 2.5 years in our hot, humid climate.

When you have your battery replaced, the technician should connect a supplementary 12-volt power supply before disconnecting the battery cables to keep onboard computers operating properly.

Keeping jumper cables in your car is also a great way to avoid being stranded. We recommend 4-gauge wire. We sell adorable lady’s battery cables.
