The internal resistance can be measured only when the batteries are fully charged and no alarm is
generated in the intelligent battery monitoring system. A measurement can be performed at least 45
minutes after the previous measurement ends. The battery internal resistance will change to an invalid
value after power-off and then power-on again. By default, the BIM checks the battery internal
resistance once every 24 hours as instructed by the CIM. The red indicator on the BIM is steady on
during the check. You can also measure the battery internal resistance manually.
