5 Warning Signs of a Failing Car Battery

A reliable car battery is essential for starting your vehicle and powering electrical components. In Kenya’s hot climate and demanding driving conditions, batteries often wear out faster than expected. Knowing the warning signs of a failing battery can save you from unexpected breakdowns and costly replacements.

Here are five key indicators that your car battery may be nearing the end of its life.

1. Slow Engine Crank

When you turn the key or push the start button, a slow or sluggish engine crank is often the first sign of a weak battery.
