MR4 meter; how long will a Wein Zinc-Air cell last?

[carl_bretteville]

Anyone have an idea as to how long I can expect a Wein Zinc-Air cell

to last in a Leicameter MR4?

Cheers,

Only a few months. It matters less which meter or camera it is in, and more that this type of cell becomes quickly exhausted from continued exposure to air. The cell will last longer if you re-cover the air holes when not in use.

 

I sent my MR-4 to Sherry. She recalibrated it for an alkaline cell that fits it.

Rob: What did Sherry charge to recalibrate your MR-4 meter?

 

Thanks.

I have read of people leaving only one hole uncovered to prolong the life, especially when used in low drain devices which I suspect a meter is.

Carl, I can not speak for wien cells but I use super cheap hearing aid zinc airs in my minolta autocord they last about 4 months and the meter is dead on. and 6 cost 4 dollars. give it a try if your not happy you are only out the cost of one wein cell. IMO the wein cell is a bunch of marketing hype and truly not anything special. Good luck with whatever you try.

Don,

Do you have a type/name on the cells you use?

Wein cells die fast, just sitting. Less than a year. Quick-n'-dirty for Ebay.

The battery to use in an MR-4 is a 625 SILVER cell. They have a far more constant voltage over their life. Even a smaller diameter #76

silver cell, with an O-ring as a spacer, is FAR better than a zinc-air cell.

Mark: Sherry charges me $38.00, but that included installing a missing washer. Which washer, I don't know. Total was $30.00 labor, $8.00 parts.

This was one of my sucessful applications for the CRISIS adapter.

Carl, The battiers I am using are energizer 625 zinc air hearing aid battieres they even come in a cool little spining dispenser 6 for 4.95 at most dept. stores.
