ql17 and hearing aid 675 ??

[utku]

hi,

I have few questions for those owning a ql17 qiii :

I use a 675 hearing aid battery 1.4v with a washer on its back, but the result is no go again.

Should I fill the cavities at the edges with foil also ?? should the battery contact with the narrow edge of the battery compartment (which is impossible without a conductive material)

thanks,

utku

just get a size 9 oring and wrap it around the battery place some tin foil on the positive side and then it should work...

utku, I sent you a PM reply on your question to me. Here is a photo of the camera that I was refering to in the reply.

And a top view,

but it is no go again.

I don't know if these will help you, but here is a picture of the battery with the #9 O-ring, I'm using in my GIII QL 17:

And a close-up of the battery compartment on my Canonet. It is shown in the correct orientation, positive side at the top:

if i understand, you place the positive side to the narrower section, right ?

Try cleaning the battery terminals with vinegar - sometimes there is a little oxidation, even if they look clean, which stops current flowing.

Please elaborate on this method. What do you use to clean the terminals? A cotton swab dipped in vinegar?

Thanks.

 

[malkav]

utuk, yes the positive side goes on the narrow side. Also be sure to wipe off the battery to remove any skin oils that come from off your fingers.

Kyle, yes just dip a cotton swab (Q-tip) in the vinegar, and wipe the terminals.

Yes - a little vinegar on a cotton bud usually cleans the terminal quite well. Alternatively, something slightly abrasive (nail file?) used gently on the terminals also works.

Or get a 1.5v LR9. Fits perfectly. The meter can be tweeked, if required, or just adjust asa rating as required.

The only problem with alkaline substitutes (other than voltage differential) is that the discharge curve can cause inaccurate readings as voltage gradually drops.

It is a Silver Oxide cell At 1.5v

It is just rewarding to to see all these photo buffs do what it takes to keep these older great camera's in the loop.

Just another website to bookmark -- Is there no end to bookmarking websites :bang:

 

[utku]

guys, thanks for the info, I've made it with #9 0ring and some foil..

malkav, my special thanks.

regards,

You are most welcome utku, glad to hear you got it working.

Utku, there is an easier way. Buy a Wein cell 1.35 volts Zinc-air battery (MRB625). When its done, remove the outer ring, and use THAT around a 675 hearing aid battery- works great !
