GPS and 2.4 Volts?

Will a Lowrance Expedition C GPS unit work with rechargeable NiMH 1.2 V batteries instead of Alkaline 1.5V? Any electronics experts out there?:thinking:

No need to be an electronics expert. The information you seek is available on the Lowrance web site. It's in the manual download section.

"Batteries
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 battery
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 alkaline
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® e2® lithium batteries and it remained afloat.
NOTE:
The battery gauge on the Satellite Status Page may not read accurately
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 alkalines.)"

My Garmin (GPS60CS) uses both, but it has a software setting to let the GPS know you are using NiMH and it adjusts the battery meter accordingly.
