The battery appears fully charged but has a low CCA. High acid concentration artificially raises the open circuit voltage. The acid concentration is light on top and heavy on the bottom. If unchecked, such a condition will eventually lead to battery failure. High acid concentration also promotes sulfation and decreases the already low conductivity further. The battery appears fully charged but provides a low CCA. High acid concentration on the bottom, on the other hand, artificially raises the open circuit voltage. A light acid limits plate activation, promotes corrosion and reduces performance. Figure 2 shows a stratified battery in which the acid concentration is light on top and heavy on the bottom. This battery provides good performance because the correct acid concentration surrounds the plates. Acid stratification reduces the overall performance of the battery.įigure 1 illustrates a normal battery in which the acid is equally distributed from top to bottom. Short distance driving while running windshield wiper and electric heaters contributes to this.

Batteries tend to stratify if kept at low charge (below 80%) and never have the opportunity to receive a full charge. This effect is similar to a cup of coffee in which the sugar collects on the bottom when the waitress forgets to bring the stirring spoon. The electrolyte on a stratified battery concentrates on the bottom, causing the upper half of the cell to be acid poor. * Source ADAC 2008 for the year 2007 Acid stratification, a problem with luxury carsĪ common cause of battery failure is acid stratification. The battery remains a weak link and the breakdowns on 1.95 million vehicles six years or less are as follows:Ī breakdown due to the battery remains the number one cause.

According to a leading European manufacturer of car batteries, factory defects amounts to less than 7 percent. Heavy accessory power when driving short distance prevents a periodic fully saturated charge that is so important for the longevity of a lead acid battery. This data is of great interest among prospective car buyers throughout the world.īattery malfunction is seldom caused by a factory defect driving habits are the more common culprits. Any service requirement during that time is recorded and the number is published in trade magazines. Good battery performance is important because problems during the warranty period tarnish customer satisfaction. North America may be shielded from these battery problems, in part because of long distance driving. The batteries in Japanese cars are small and only provide enough power to crank the engine and perform some rudimentary functions. As a result, the batteries will never get fully charged and sulfation occurs. The average car is only driven 13 km (8 miles) per day and mostly in a congested city. In Japan, battery failure is the largest complaint among new car owners. The car manufacturer says that the problem is more common on large luxury cars offering power-hungry auxiliary options than on the more basic models. Low charge and acid stratification are the most common causes of the apparent failure.

Your local Meineke has the equipment and highly trained mechanics to install and meet all of your car battery inspection, service, replacement and installation needs.Driving habits rather than battery defect are often the cause of battery failure.Ī German manufacturer of luxury cars reveals that of 400 car batteries returned under warranty, 200 are working well and have no problem. This type of test includes determining the electrical draw of the starter and the output of the alternator. If your battery has adequate capacity but still is losing its charge, further testing is required.
