The following table summarizes battery operation:

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.

Operating Time (typ): 3 hours (below +35 °C)

Standby Time (typ): 24 hours (below +35

°C, OCXO powered)

Recharge Time (typ): 4 hours to 100% capacity or 2 hours to 90% capacity

Temperature Range: 0

°C to +55 °C (operating) - battery charges below +35 °C

-10

°C to +60 °C (storage)

NOTE

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.
