I just cant help thinking if its that bloody critical then the HH uses the wrong batteries.

It should use something with adequate power reserves that is not living on the edge of failure all the time.

Id rather it ran on two C cells and just worked than all this pissing about.

AAis in the hand sets is very cool but ONLY if it works reliably.

Using the above numbers at a continuous draw of above that would mean about 4 hours of use for a 1.5v AA cell before the derating of current and cold..

The biggest derating would be that of the cold.. Near freezing you have well under 50% of the rated capacity... So I would say worse case of a single AA alkaline in near freezing water should be atleast 1 hour but less than 2 hours.. Test and reports that have been made were that a few experienced issues in near freezing conditions at 90 mins, so the ratings are reasonable..

Lithium cells wount get anywhere near the derating of Alkaline cells due to cold colditions..
