hi, i was given a Gossen Super Pilot lightmeter, and put new battery WeinCell 1.3V as specified.
With very little usage, a few times for a quick reading, the battery went flat in around 3 months. Despite the fact that the meter is stored in its case, and inside camera bag.
Is this time normal for these batteries to go flat? The battery was new, is it possible that the meter is shorting somewhere and drains the battery?
thank you.

I haven't actually used these batteries, myself, but from what I've read, once you remove the plastic membrane, open the vents, and allow the chemical process to start, zinc-air batteries have a very short lifespan of only "a few" months.
I have heard of some people saving the plastic membrane and covering the vents when the batteries are not in use, to prolong their life, but I don't know if this actually works.
These batteries are most useful for intensive use over a short period of time. Otherwise, you might be better served by an MR-9 adapter (such as the CRIS adapter) for use with a silver-oxide cell.

I have an original battery in my Gossen Sixtar which I think is the same meter as the Super Pilot. I haven't used if much but the battery could be twenty years old or more. Weird.

hi, that seems to explain it... thanks!
yes it is the same meter. mine is also sixtar but i thought it was more known as super pilot that's why i used this name. twenty years is insane, though you probably have original mercury battery, not the replacement batteries we talk about.

I put a wein cell in my Ricoh 500GX and it lasted for less than 20 shots. I now use an SR44 which works and the meter gives good readings as I've had a few films through it.
