Power
The iFINDER operates from AA batteries or on 3 volts DC using an
optional external power cable with a cigarette lighter adapter. When
the power cable is used, the iFINDER automatically switches to it if the
external power is greater than the battery voltage. If the external
power fails, the unit automatically switches to the batteries.
Flash memory will keep your stored data safe and accessible for the life
of the product — after the unit is turned off, no battery or external
power is needed to store your data.
Batteries
The unit requires two, 1.5 volt AA batteries. We recommend that you
use alkaline batteries for the best trade-off between battery life and
cost. We recommend DURACELL

brand, but other brands will work.
If you're looking for an extended-life battery, the Duracell

ULTRA bat-
tery has performed well in our tests.
You can also use rechargeable AA alkaline batteries, such as those
made by RAYOVAC

, or rechargeable AA nickel metal hydride (NiMH)
batteries. We do not recommend nickel cadmium (NiCd) rechargeable
batteries because we tend to get poor battery life from them.
Rechargeable alkaline batteries will not last as long as standard alka-
line batteries. However, rechargeable NiMH batteries should give you
suitable battery life.
NOTE:
The battery gauge on the Satellite Status Page may not read accu-
rately with some battery brands because discharge rates can vary
significantly. This is especially true for rechargeables. This battery
gauge was calibrated for alkaline batteries.
Do not mix different battery types. Mixing battery types may cause
leakage. (For example, don’t use both alkaline and NiMH batteries at
the same time, and don't use standard alkalines with rechargeable al-
kalines.)
