a. The nominal voltage is defined as being 15% higher than the lower extreme voltage. TA will test with this
nominal voltage at an 85% range (0.85x3.9V
b. This limit is set to be above SW shutdown limit in TA.
c. During fast charging of an empty battery, this voltage might exceed this value. Voltages between 4.20 and
4.60 might appear for a short while.
d. The minimum battery cell voltage required for the reset circuitry to turn on. This is not confirmed by
measures at pt.
