Are there tell-tale signs that my car battery is about to die?

Possibly. One sign may be that you hear the starter turning the engine more slowly than usual on starting the car. This is a sign the battery may be struggling. The battery light on the dashboard may light up, although this is not always an indication the battery is going to die. Be aware of battery leaks and any scaly build-up on the terminals. An older battery (more than three years) is less likely to stand extreme weather conditions. Very hot or cold weather may cause it to fail sooner. And when it does fail it’s also possible that it’s not preceded by any noticeable warning signs at all.
