When it comes to vehicle maintenance, "normal" is determined by a number of factors that exist in theory but rarely come to pass.

For instance, a battery has an average normal lifespan of four years under normal conditions. "Normal" in this case means the battery goes through full charge cycles, isn't subjected to extreme temperatures, is attached to a reliable and consistent charging system and isn't providing power for a ton of accessories.

But normal just isn't normal.

In the real world, temperature extremes, vibration, short trips down the street and an ever-increasing array of smartphones, aftermarket navigation systems, and other devices all take a toll on the battery.
