Car Battery

HOW TO DETECT THE BATTERY FAILURE

The battery diagnosis should begin with a visual inspection. For this purpose, you have to open access to its internal part where the plates are situated. For this you just need to remove a special cap in the top cover. To begin with, assess the electrolyte fluid color. The fluid must be clear. If it is dark or red tinted, this indicates that the battery plates have deteriorated. Such a device requires replacement. Next, check if the electrolyte fluid amount in the device is sufficient: all the battery plates must be completely covered with fluid. If the fluid level is insufficient, it must be refilled.

Next, check the battery charge level. This can be done with a voltage meter or a multimeter. The nominal value is 12.5-13V. The upper limit indicates that the battery is fully charged, the lower limit corresponds to a half discharge. The voltage reading for the loaded battery should be between 13.5 and 14V. If it is lower, this indicates that the car alternator is faulty.
