Battery Save Mode (60cs/x)

| battery save mode is mentioned just once in the manual, where they
informatively tell you how to switch to... BATTERY SAVE MODE. What they
don't mention is, how is battery save mode different from normal mode?
Is it less accurate? Are the beeps quieter? Does the map update less
often? And how much battery does it actually save? I read in one forum
that WAAS is "not compatable" with battery save mode. And yet, I can
enable WAAS when battery save mode is on and it doesn't seem to give me
any warnings and there's nothing like that mentioned in the manual.
Does anyone knows what it actually does, what kind of a difference it
actually makes in terms of battery life?
(as an aside, I assume where it lets you select battery type
Alkaline/Nimh - this is used only for battery life estimation?)

Battery Save mode increases the minimum SV elevation (to 30 degrees, if I
remember correctly) and disables WAAS. With fewer SVs used, accuracy is
decreased.

Yes. Alkaline batteries drop off evenly from 1.5V, while NiMH drop off
slowly,and then quickly, from 1.2V.

I don't have very precise details, but the going recommendation
is not to use battery save mode, mainly because it increases the
number of communication loss situations when reception is
difficult.
Use it only when you're really short of power.

this mode was present with early Garmin receivers, then it was dropped, now
it came back. Assuming that it works the same as in the old days:
when detecting constant movement (or no movement), it switches off the front
end of the receiver for some seconds, and it extrapolates the constant
movement during this off-time. So it may detect a directional change later,
and it may log to a re-appearing satellite later than possible.
I never use this mode. I use rechargeable batteries. Battery saving is no
concern to me.
