Why Is Your Vehicle Draining Your Battery?

At A1 Automotive Center in Eustis, we know how annoying a dead battery can be. Here’s some information on the subject, that will hopefully help you understand your battery issues a little better. If your battery dies after your car, truck, or SUV sits for a few hours, the battery itself isn’t necessarily the problem. While having the battery tested is a good place to start, many people mistakenly make a bad battery diagnosis, when actually something in the electrical system is to blame.

Battery drains can be difficult to track down. If you have a multimeter, you can use it to check for current between the positive terminal on the battery and a ground point, with the key off. While many modern vehicles will produce a slight drain due to anti-theft systems or memory-capable devices, anything significant should be a cause for concern. All vehicles are different, but a simple google search will typically clue you in to what sort of drain is normal for your vehicle.

If you think you have a battery drain, check to make sure all lights, including brake lights, glove compartment lights, etc. turn off properly when the car is shut down...the drain could be a result of a bad brake light switch or door switch. More often than not, however, a drain is caused by a shorted wire somewhere; any malfunctioning electronics are a likely culprit, but not necessarily a symptom. These drains are invisible to the naked eye and require much more in-depth investigation.
