Battery Care
When the battery is enabled and the instrument is not connected to AC power,
the battery discharges at 30% of full capacity per day. When the battery is
disabled and AC power is not connected, the battery discharges at 10% of full
capacity per month.
When storing the instrument without AC power applied, do not allow the battery
to discharge below 10%. The following equation can be used to determine
instrument storage time without AC power - and still enable the instrument to be
fully recharged:
months battery disabled * 10% + days battery enabled * 30% = 90%
A fully discharged battery may need to be replaced if it has not been recharged for
six to 18 months.
If battery operation is in use above the maximum specified operating
temperature, the battery will shut down the instrument to preserve its use. AC
power must be applied to recover from a shut down caused by this condition.
