3.85V/4.4V High Voltage Cells
3.85V/4.40V high-voltage battery is a higher voltage relative to ordinary batteries (3.7V/4.2V), 3.85V indicator nominal voltage, 4.40V refers to the full charge voltage (also called charge cut-off voltage), that is, high-voltage battery is defined according to the voltage of the single battery cell, mainly for lithium batteries, 3.85V/4.40V high-voltage battery can also be called 3.85V / 4.40V lithium high-voltage battery (LiHv).
