Re: Batteries

I'm looking in an old Burgess manual at the Hg 625R and
it shows at a low drain, like 3 mA, the life to 1.2 V
is 75 hours and the life to 0.9 V is 80 hours.  So at
low drain, the voltage drops like a rock at the end.
My recollection is that the R type depolarizer gives
you a lower voltage (1.35 vs 1.40) but a stabler voltage
but lower energy density.  Not too much on that subject in
this manual.

I don't have any current stuff on silver cells and no curves.
Just a listing of the voltage.  Fooling around last night,
I found the silver and alkaline no load voltages of new
cells at 70F was the same down to about 1 mV.

Anyone have some curves on silver?

Thanks,
John
