Checking Battery Health; Error Status - Dell PW7018LC User Manual

Checking battery health

Battery health is a measurement reflecting the general condition of the battery. It indicates
how much battery life remains before the power bank must be replaced.
NOTE: The units of SOH (State Of Health) are percentage (%) points.
A battery's SOH is 100% at the time of manufacture and will deteriorate gradually with
usage.
Press and hold the power button for 5 seconds to turn on the power bank and check the
battery health status.
