[IP] Anyone tried Zinc Air batteries?
>Has anyone ever tried a Zinc-Air battery?
I haven't. But before you do, you might want to take a look at that
battery's characteristic curve. To see such curves for the silver oxide
357and manganese dioxide A76/LR44, have a look here:
The zinc air AC675 data is here:
Take a good look at the zinc-air curve and compare to that of the
silver-oxide. The zinc-air battery is not at all designed for the same
service. The silver-oxide batter, OTOH, appears to be very well matched to
pump service requirements.
>the store clerk wanted to argue that "a 1.5V battery is the same as
>another 1.5V battery".... I told her I wanted silver oxide
The clerk is mistaken. Take a look at the characteristic curves. It's quite
BTW, here are (purportedly) some 357-type models packaged under different
303 or 357-1W Rayovac
D303 or D357 Duracell
SR44W Sony, Toshiba
>Here's a few of the batteries, and their charge capacity
The battery is an essential part of the pump. The pump has been designed
around it. And the recommended battery is _not_ expensive. (I just bought
357's for $1 each. I got'em here:

month. So the payoff is meager. I'd strongly advise against this kind of
experiment, but, of course, it's your pump and your call.
