Battery charge management follows a constant-current,
constant-voltage (CCCV) scheme, with a charge-time
cutoff. A maximum absolute temperature shutoff
ensures that the maximum charge is provided to the
battery, but does not reach temperatures high enough
to cause damage or limit lifetime.
Battery Technology
The UltraBookIIi uses a lithium-ion battery module to
power the workstation when AC power is not available.
The lithium-ion battery module has a gravimetric power
density 100% higher than NiMH or NiCd batteries and
suffers no memory effect from the recharge cycle. The
battery device bay is located at the front-right side of the
workstation below the onboard audio input/output
jacks, as shown in Figure A-4.
The 4050 mAH battery module provides approximately
one hour of continuous-use battery operation,
depending on system configuration. The battery module
has nine cells, supplying 10 volts nominal to the internal
DC power converter.
