- If I have to use the display backlight, likewise.
- If I use the (Gilsson) external active antenna, it drains the batteries a bit (but not significally).
I normally use rechargeable 2300 mAh NiMhs, a step up from my old 1800 mAh ones.
As long as you bring a spare set you'll be okay, the unit just picks up where it left atfter a battery change. (Just remember to recalibrate the magnetic compass on the S-models.) Units with unreplaceable batteries are unsuited for my kind of use, which involves kayaking/biking/trekking for days away from any AC outlets.
