Base Charge Mode
In order for the battery to be charged, there must be enough voltage for the
circuitry to work. There are three conditions during which power can be supplied
to the base:
Condition 1: 9VDC power supply connected to the barrel connector
Condition 2: 12VDC host power source only
Condition 3: 5VDC host power source only
The chart below describes each selection by condition.
Using a slow charge rate draws less current (power) from the input power source
when the battery is mostly discharged.
Scan the appropriate bar code for your application.
