Battery Care - Agilent Technologies 53220A User Manual

1 Preparation for Use
The following table summarizes battery operation:
If battery operation is in use above the maximum specified operating temperature, the
N O TE
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.
For a complete list of battery and all 53220A/53230A product specifications, refer to the
N O TE
data sheet included on the 53210A/53220A/53230A Product Reference CD
(p/n 53220-13601), or on the Web at:

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.
