Some news channels suggest a third of lead-acid starter batteries could fail with the first cold snap this winter. While we are not entirely convinced this number is accurate, it certainly does confirm the trend of previous years. Not being able to crank over a gasoline engine on a chilly morning is nobody’s idea of fun. With that in mind, we decided to remind our readers of seven common starter battery warning signs.
7 Warning Signs a Lead-Acid Starter Battery is Aging
- Your lead battery is more than three years old. This is not sufficient reason to change it, but it definitely will not last forever.
- You pop the hood and notice white powder on the battery connections. The starter battery is not charging correctly. Have it tested.
- The navigation lights on the car are not as bright as you expect. This is one of the classic starter battery warning signs to watch for.
- A low battery warning light illuminates on the dashboard. Take this message seriously. Have the battery tested.
- The starter motor cranks over slowly. This is a definite indication that your battery is running out of steam.
- You notice a ‘rotten egg’ smell in the car. Your battery is leaking hydrogen gas. Make an appointment for a replacement.
- The battery case is distorted or swollen. You have a real problem! Ask a battery supplier to call around and install a new battery.
Lead acid batteries release hydrogen and oxygen while charging, and this can leak out if the battery case is damaged. They also contain a quantity of sulfuric acid, which can burn skin. Always replace a starter battery before it gives trouble, and you may never need to push start, or jump start your car again.
