BBU for up to 24 hours, click OK to continue.
After the battery test starts, you will see the voltage start dropping;
eventually the battery voltage will say "LOW". This is part of the battery
test. After the voltage drops to a point, it will start charging again, and the
status will change to "Charging." Eventually, the battery voltage will say
"OK" again.
