No cranking capacity
No cranking capacity
So the end of a starter battery’s service life is usually announced by No cranking capacity. especially at low temperatures. Of course, that could very well be caused by normal wear. As a result, a battery is subject to two natural wear processes.
1. Corrosion of the (positive) grid and loss of active mass These processes are taking place gradually, never suddenly. Unfortunately, that is not to say that the symptoms are not constant from one day to the next.
2. Significantly, a good night-frost can make painfully clear what was previously unnoticed at higher temperatures!
How to fix no cranking capacity, If the problem does occur prematurely, it has most likely been caused by overcharging and/or excessive temperature. In which case, it is important to check the alternator to stop it from happening again!
A second cause can be found in loss of active mass by deep discharge.
It’s no surprise if the battery has No cranking capacity car battery, to meet the energy requirements of the vehicle. After that, of course, the same is true for starter batteries that don’t get enough charge.
Short trips during which the dynamo cannot fully charge the battery Of course, this will eventually bring the battery into a permanent state of deep discharge. naturally, which severely cuts battery life.
Another cause of battery problems failure is often overlooked- acid stratification. So, the electrolyte in a stratified battery concentrates at the bottom. So, causing the upper half of the cell to be deprived of it. Consequently, the upper half of the cell is deprived of acid.
Which will limit plate activity.
Thus, promoting corrosion and reduced performance. Whilst the acid concentration is light on top, it is heavy at the bottom. Such a high acid concentration artificially raises the open circuit voltage. The battery appears fully charged but has a low CCA. (No cranking capacity)
Driving habits rather than battery defect are often the cause of battery failure.
Explicitly, a manufacturer of luxury cars reveals that 400 car batteries were returned under warranty. Hence, 200 are working well and have no problems. So, the most common reasons for the apparent failure are a low charge and a layer of acid.
The car manufacturer says that the problem is more common in large luxury cars. offering power-hungry auxiliary options, rather than on the more basic models. Trojan batteries also offer a good battery maintenance guide.
