Checking The Battery Health; Error Status - Dell PH45W17-BA User Manual

Checking the 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 five seconds to turn on the power bank then check the
battery health status.
