Things to do Before Removing the Car Battery

Posted by Bestow on May 5th, 2014

Automotive batteries don't last forever. If you notice your headlights dimming, or if it's been 3-7 years since you got a new battery, or the car needs a jump-start, it might be time for a change. You can bring your vehicle to an experienced and trusted auto mechanic, or you can get the job done yourself. Changing a battery is a quick and easy job in most cars and vans and can be done with minimal Mechanic tools.

Set up a secure working environment. Park on a flat, level surface at a safe distance from traffic sparks or opens flames. Put on the parking brake. Don't smoke, and make sure any smokers in proximity to the working area know not to smoke as well. Remember that electricity is not the only danger; batteries contain a sulfuric acid electrolyte solution, which is highly corrosive (i.e. can burn your skin) and produces a flammable gas. Put on gloves and safety goggles.

Remove the cigarette lighter and plug the memory keeper into the lighter socket. A Complementary metal–oxide–semiconductor (CMOS) will keep the PIN codes and settings for radios and navigation systems from getting erased when you disconnect the battery. If you don't have a memory keeper make sure you have all the PINs for your electronic equipment before you start. You may wish to check your car manual to see what devices may be affected.

After opening your hood, use the prop rod to keep your hood open (Most newer cars have hoods that hold themselves up.
