On average, automotive car batteries will last 3 to 5 years.

Consequently, driving habits and exposure to extreme elements can shorten the life of a car battery.

  • So, ever wonder why your car won’t start? One of the reasons may be weak or dead car batteries.
  • If you have a battery tester that can measure cranking amps, use it to see if the battery is weak.
  • But, if you can’t test the battery, try jump-starting.
  • So, if the car starts right away, your problem is most likely a dead battery.
  • Finally, charge the battery and clean the terminals and cable connectors to ensure good contact.

In contrast, If your car does not start by jump-starting, you may have a problem with your:

  • Starter
  • Alternator
  • Electrical system

Different Battery Types

There are many different kinds of car batteries with each having their own classifications. The most popular and commonly used are lead-acid batteries, particularly flooded, gel and Absorbed Glass Mat (AGM) models. While each of these types utilizes the same basic chemistry, the lifespans, power, and maintenance requirements vary between them.

Flooded

Flooded lead-acid car batteries are far and away the most common battery in use today. Named after its free-flowing electrolyte solution, flooded batteries are susceptible to spills if not fully secured in the vehicle.

Gel

Unlike flooded batteries, gel lead-acid car batteries utilize a Jello like substance in place of a liquid electrolyte solution. Also, helping to prevent leakage and provide consistent electrolyte coverage around lead plates. But, gel batteries are more susceptible to voltage inconsistencies and must be replaced at the end of their lifespan.

AGM

Unlike the previous two types of lead-acid car batteries, AGM batteries utilize fiberglass sheets to separate lead plates and electrolytes. Because each cell is tightly wound and contained, these batteries are extremely stable and leak resistant. In addition to their heightened stability, AGM batteries are arguably the most efficient lead-acid type. Because, they perform better in colder conditions (higher cold crank amperage), have a longer life, and recharge quickly.
