New article “Field experiences in battery internal resistance and capacity testing”

In order to remain reliable, stationary batteries require maintenance and care over their service life. A large number of tests have been performed and described in order to determine the condition of the battery.

Capacity tests are used to reliably determine battery capacity. The results of capacity tests are then used to evaluate whether the battery can continue in service or needs to be replaced. Many batteries do not receive regular capacity testing due to several myths and misunderstandings, also the measurement of battery resistance is becoming a popular alternative test method.

Both tests are useful in detecting deteriorated cells, however there are some initiatives to replace capacity testing with internal resistance testing. This paper shows some field experiences with internal resistance tests and capacity testing. In addition, it provides a comparison between these two tests. The conclusion discusses some merits and short comings of each test.
