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
companion 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
companion and check the battery health status.
