[glondor]

Any one have any interest in purchasing 3.75 kilos of hearing aid batteries. There is also 132 grams of gold plated hearing aid batteries.

PM me if you are interested.

what brand are most of these batteries and do they say SR on them?

 

[glondor]

I will check them tomorrow. My daughter spent most of the day sorting them for me so I have not been up close and personal with them.

MERCURY ALERT!!!!!!!!

Golden plated button cells(in the upper left corner) do not contain any silver,instead they contain a lot of mercury...if you open one of these batteries liquid mercury will flow...keep in hand some crude egg white if mercury drops to the floor,crude egg white collects all little drops of mercury.

Take a look to the post I wrote to select and process silver button cells.

Kindest Regards.

Hi Manuel. I am glad you came in on this post. Is there a sure fire way to identify these batteries? Not a single one has any markings, No makers marks at all. They all came from a hearing aid manufacturer.

Thanks for the heads up on the gold topped ones. They will be handled with care.

I have read your work on batteries and I thank you for putting it together for us.

Cheers!.

Glondor:

Mercury cells do not contain any letter,instead,silver cells have "SR" or a number(e.g. "376").

All button cells have their fabricant´s name...except those of mercury...nobody wants to add a company´s name to the word"mercury" and this is the key to identify these button cells because they do not contain any letter or number,some times they have 4 dots.

If you have a button cell that does not contain any letter or name then it is a mercury type.

Kindest regrads.

Thanks Manuel. I will retain these until I have time to sample a cross section of the population of batteries. I hope they are not Mercury, although with your info I fear they may be. I will drill and sample 100 or so and see what the results are. I will keep you posted. I have Mercury cartridges and sarinex suits so I will be protected.

Are those vent holes in the tops?

If they are they are zinc air batteries.

Interesting. Thanks for the lead. I will look in to the zinc batteries some more.

Well I opened some of the gold topped batteries and there was no mercury. Just a bluish grey powder. I will open some of the non gold ones after lunch.

Wow! How many batteries! It seems that it is high time to start collecting my hearing aid batteries.

I have tons as well. Recently ordered myself some new hearing aid batteries online, as i don't want to run out of them in a most uncomfortable moment. Some people forget how important is that to keep an extra pair of batteries for the emergency cases.
