Interesting facts about car batteries and what makes them go dead before their projected lifespan expires. If you keep your vehicle the average 5 to 7 years that most people do chances are you will need to learn something about batteries along the way.
With the average car battery only lasting 3 to 5 years and some not even that long due to harsh conditions, you may have to deal with the battery issue more than once.
Side note: A car battery can be dangerous! You should always wear safety glasses. You should always work in a well ventilated area. It is rare that it will explode but it can happen! The invisible gasses floating above can be triggered by sparks, flames or even cigarette ashes.
What shortens a batteries life?
An overcharging condition can cause a boiling condition inside the battery that eventually will reduce the amount of water and electrolyte in the cells.
Alternator
An overcharge condition can be caused by the vehicle’s on-board alternator stemming from problems with voltage regulators or even the alternator itself.
A charging system test can reveal a problem with the on board system. Also automatic battery chargers can cause this same condition when the charger does not live up to its automatic functions.
You may not be able to do anything about this next cause of a shortened battery life if you have a sealed maintenance-free battery which most of us do.
In proper electrolyte levels in the battery cells will reduce the batteries storage capacity. Electrolyte can be lost due to evaporation during hot weather as well as an overcharge condition mentioned above.
