6. The battery will lose its charge during storage.
If stored inserted in your instrument, this loss will
be more noteworthy. It is recommended that the
battery be removed from the instrument during
periods of storage. It is not advisable to store re-
chargeable batteries for long periods of time with-
out use. If however, storage is necessary, store
without a charge (discharged).
7. Do not discharge the battery in devices other
than your metal detector. Unnecessary discharging
and/or an absolute discharge will reduce battery life
and may damage the battery. Unlike older recharge-
able battery designs, the rechargeable battery
provided with your detector can be recharged at any
time. Regardless of whether or not it already has a
partial charge, memory will not occur.
8. White's has provided the leading edge of re-
chargeable battery technology with your instru-
ment. Disregard all advice which conflicts with the
above recommendations. Care for batteries pro-
vided by other manufacturers, or with other White's
models, may vary.
Charging
1. There is no harm charg-
ing overnight using the
OVERNIGHT charger
setting regardless of the
battery's current condition.
However, before charging
with the QUICK charger
setting, determine battery
condition by inserting
battery into the instrument
and turning the instrument
ON. If the instrument will
not turn ON, or if voltage
tests eight volts or below,
charge five hours with the
QUICK charge. If the battery voltage tests any other
voltage, refer to the Charging Hours chart above for
proper QUICK charge time.
2. To charge, insert the charger plug into the battery
pack jack, located near the plastic tab and
metal contact points.
3. Plug the charger into a standard wall outlet.
(110 volts for USA models).
4. Again, the QUICK charger setting uses the
above chart for a specific charge time. OVER-
NIGHT is designed to charge the battery in as little
as fourteen hours. However, no harm will come to
the system leaving it charging for several days.
5. It is normal for the battery and charger to get
warm during use. However, if either the battery or
the charger gets too hot to hold or deforms due to
the heat, discontinue use and return for testing.
