The Causes of Battery Degradation

Batteries can suffer significant deterioration due to improper usage behaviors. Major causes include:

• Deep battery voltagedischarge
• Out-of-specification absorption of the battery
• Uncontrolled charging in voltage
• Charging not limited in Current according to battery specification
• Incorrect compensation of charging according to the temperature of the charging environment

All these can soon have a negative effect on the health of a battery.

Common Failure Modes

Various common failure modes such as sulfation, element short-circuiting, and element dryness are a consequence of careless use and can rapidly degrade the health of the battery.

Diagnosis: A Complex Challenge

It is not at all easy to know the true health status of the battery. In order to properly stimulate the battery and consequently receive from it all the data needed to make a diagnosis, very careful and adaptive stimulation and reading algorithms are needed.

As a result, the performance test will detect batteries in which the health status has declined to the point of life depletion.
