In general NiMH batteries loose capacity (read efficiency) when cold (<10 oC), AND loose voltage (slightly) A problem rises when a GPS has a "low battery switch off" which may be fooled by that phenomenon. I owe a Nikon camera (used when mapping) that cannot operate on rechargeable batteries when below 10 degrees, in spite of a special NiMH battery setting. It takes 2 or 3 pictures before the camera switches off with a low battery message.
Back at home everything works fine again.

FWIW I use 2500-2900 mAh NiMH batteries with my 60CSx while hiking in Iceland, typically in colds around -10 C to -5 C degrees and a pair of them still seems to last about a day or so. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
