"Some batteries are equipped with a solid-state switch that is normally
in the "off" position and no voltage is present at the battery
terminals. Connecting the switch terminal to ground or pulling it up
often turns the battery on. If this does not work, the pack may need a
code for activation. Battery manufacturers keep these proprietary codes
a well-guarded secret to which even service personnel have no access."
