Just like tires or wiper blades, belts and hoses, batteries wear out. If you could see into the interior of a worn battery, you would be able to see the material that has shed from the battery’s internal plates over the lifetime of the battery
The number one cause of battery plate shedding is heat, both environmental and from normal vehicle operation. Over time, high temperatures gradually break down your battery. The second most common cause is vibration. The constant jostling and bouncing your vehicle experiences as you drive also contributes to plate shedding. The build-up of the material shed from your battery plates is what eventually causes a battery to fail.
As your battery ages, the CCA reading will continue to decrease until it falls below the manufacturer’s rating. When the test decision is “Replace”, it means that your battery no longer meets industry standards and will soon fail. By having your battery tested regularly, you will know when to replace it before it fails and leaves you stranded.
The Solar BA9 Battery and System Tester from Clore Automotive is optimized to test four distinct battery types: Conventional Flooded Acid, AGM Flat Plate, AGM Spiral Wound and Gel Cell batteries. It also features the convenience of starting and charging system testing, offering quick assessment and providing both a numerical result and a pass/fail result.
