Working with the Lithium-Ion Battery
Charging the Battery
The battery in your FieldFox will have either 4 or 5 LED segments.
Charging the Battery
When you receive your FieldFox, the lithium-ion battery is partially charged to
approximately 30% to 40% to preserve battery life. Allow four hours to fully
charge the battery internally, or three and a half hours () by using the external
battery charger (N9910X–872). A fully charged battery will power your
FieldFox for about four hours. Upon receiving your FieldFox, it is NOT
necessary to charge your FieldFox's battery before using your instrument.
The FieldFox circuitry ALWAYS prevents the battery from discharging to a level
that is damaging. However, if the battery is completely discharged, the
FieldFox may not turn ON. If this occurs, the battery can still be charged either
internally or externally.
Because a lithium-ion battery has no memory effect, you can charge a battery
at any time regardless of the current charge status.
Internal Charging with the AC/DC Adapter
Internal charging time for a fully depleted battery is approximately 4 hours with
the FieldFox either ON or OFF.
