No, it doesn't. But it is enough to query "info" once:
"state" contains:
  present:                 yes
  capacity state:          ok
  charging state:          unknown
  present rate:            unknown
  remaining capacity:      57420 mWh
  present voltage:         16758 mV
"info" contains (only values useful for monitoring listed here):
  design capacity:         57420 mWh
  last full capacity:      57420 mWh
  battery technology:      rechargeable
  design voltage:          14800 mV
  design capacity warning: 3000 mWh
  design capacity low:     1000 mWh
  capacity granularity 1:  200 mWh
  capacity granularity 2:  200 mWh
None of which is expected to change during useage of the battery.
So querying once is enough: all variable values are in "state".

Erich
