Car Battery Myths and Facts

We have been in the battery industry longer than we like to admit sometimes.  Over the years, it’s been amazing to hear the same myths about batteries over and over again.  Some pertain to storing automotive batteries, others have to do with how it charges or what do do when a battery dies.  We put together this article to talk about some of the most common car battery myths and facts we have heard over the years.

Storing a Battery On Concrete will Drain it

This is by far one of the largest myths out there, though there is some historic fact behind it.  First, let us just say storing a modern battery on concrete will not cause it to leak or discharge.  Concrete is actually a great surface to store a modern, plastic encased battery on.  We hear this common misconception all of the time.

The first lead-acid batteries were encased in wooded boxes that were tar lined.  Inside of these boxes were glass cells.  If one of these early batteries were stored on a wet concrete floor, the wood would swell and cause the glass to break.  This in turn caused the batteries to leak.

As batteries developed, they became encased in steel, also known as Edison cells.  If stored on concrete it could actually discharge quite easily.  The same was true for the first rubber encased batteries.  If stored on a damp floor, the cells could form electrical currents to one another and discharge the battery.

Modern batteries do not have any of these issues, and a concrete floor will not drain them or cause them to leak at all.

Driving for 30 Minutes After a Jump Start Charges my Battery

This is another common myth people believe because someone told them it was true.  It is of course true that if you jump your car battery you are in a sense “recharging” it.  However, the best way to deal with a battery that has died is to have it truly recharged by a multi stage battery charger.  This will help bring the battery back to a full charge.  This simply isn’t possible when you jump start your car.

When your battery fully dischargers and you cannot start your car, you are reducing the amount of life your battery has every time you jump start it.  Although your car may feel and run ok, your battery is still not charged to it’s full capacity.  Over time, this causes more strain on your electrical charging system which can cause components like your alternator to wear out faster.  Also, a weak battery can negatively impact gas mileage.

Car Batteries Last Longer in Hot Climates than in Cold Climates.

False.  People here in Florida seem to think that because car batteries do not have to strain against the cold weather, they will last longer.  It’s actually the other way around.  In sealed, maintenance free batteries the water levels actually evaporate much faster in a hot climate like Florida.  In cold temperatures, the water levels remain much more consistent for a longer period of  time.

Removing the Battery While the Car is on Tests the Alternator

When it comes to car battery myths and facts, we have to shake our head at this one.  It is never safe to remove a battery from a running vehicle.  Ever.  Other than the potential risk of explosion, you can seriously damage your car’s electronic components.  Modern cars are full of computers and sensors that rely on consistent power levels.  Your car battery actually helps control power spikes, almost as if it were a filter for the power in your car.  When you remove it, power spikes can short everything out.
