FieldFox User’s Guide
3. Fully discharge the battery by disconnecting the AC/DC adapter, then leave
the FieldFox ON until it shuts down (about four to five hours).
4. Remove the battery from the FieldFox, wait one minute, then re-install the
battery.
5. Reconnect the AC/DC adapter.
6. Charge the battery and verify a full charge.
7. Check the
System
then
Service Diagnostics
then
Battery
screen to verify
that the Max Error is less than 10%.
How to Recondition with the External Battery Charger (N9910X–872)
1. Insert a battery into the left bay of the external charger.
2. Press the button labeled Push to Recalibrate Left Battery Bay
3. The charger will charge the battery fully, discharge it completely, then
recharge it fully again. The entire process can take up to 12 hours.
4. Install the battery into the FieldFox.
5. On the System, Battery screen, verify that the battery is fully charged and
reconditioned.
Battery Care
Visually inspect the battery periodically for signs of degradation, such as
swelling, cracking of the battery shell, or leakage of fluid. If degradation occurs,
replace the battery and dispose of it properly. Learn how on page 221. Operation
with a degraded battery could result in damage to the FieldFox. Learn more on
page 225.
Maximizing Battery Life
If AC power is not continuously available (Ex: in a field environment), use the
battery and recharge it when it holds a 20% to 50% charge, as shown on the
screen’s battery charge icon. At this charge level, 2 or 3 segments show on the
battery gauge.
If the FieldFox is not going to be used for more than a week, remove the
battery. Best practice is to store the battery with a charge of about 50%. At this
charge level, 3 segments show on the battery gauge. Batteries that remain idle
eventually lose their ability to hold a charge.
Allow a battery to warm to room temperature before charging it. Temperature
shock can damage the battery chemistry and in some cases cause a short
circuit.
Store batteries in a cool, dry location, away from metal objects and corrosive
gases.
Storage temperature limits (20% to 50% relative charge is recommended):
Transportation:
–20°C to 50°C
Within 1 month:
–20°C to 45°C
Within 6 months: –20°C to 40°C
Within 1 year:
–20°C to 35°C
Battery charging limits:
Charge temperature:
0°C to 45°C (<10°C slows charge on some batteries)
Discharge temperature: –10°C to 60°C
