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 exter-

nal power. If the external power fails, the unit will switch to battery 

power.  
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. 

The unit requires two, 1.5-volt AA batteries. We recommend 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. Rechargeable NiMH batteries, however, should give you 

suitable battery life. 
Lithium batteries are lighter than alkaline, and with some brands of 

lithium batteries, the iFINDER ExpeditionC will float. We've tested it 
using Energizer

®

 e

2®

 lithium batteries and it remained afloat. 

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 leak-

age. (For example, don’t use both alkaline and NiMH batteries at the 

same time, and don't use standard alkalines with rechargeable alkalines.)
