What Are Signs of a Failing Battery?

If your car, truck, or SUV battery is beginning to fail, you will have some distinct signs to give you time to get to a certified mechanic in Columbia, IL so you won't be stranded on the side of the road. Some of the signs you may notice when you need your battery inspected and tested are a rotten egg smell under the hood. Lead-acid batteries have water and sulfuric acid in the cells and when some of it evaporates over time from using it will create an odor and it can overheat or boil. Slow-cranking is a sign of a failing battery because it doesn't have enough energy stored to crank your car as usual. If your battery light on the dashboard illuminates or your car displays a message to check your battery on the dash, this indicator will turn on and stay on until you have your battery serviced or replaced. If your electrical powered items are not working or working slowly, such as windows and dash lights, your battery may be failing.
