I have an old Realistic pwr mic that uses a 7v mercury battery. Can't get those anymore. Would the 6v or 7.5v alkaline work?

Do a Google search for:
TwinPoint/Workman T175 7 volt battery.
Product Description:
Works on some of the older power mics like Turner M+2 and Astatic D104, Older Realistics and Cobra Power mics.
Hope this helps.

Thats too funny!! I was told at a battery shop in Reno that the 7volt was no longer made. I took it as gospel !! and I never even looked any further. oops !! I will order one with the CS-400 coax after I get a question answered I posted in the Ask a tech forum.
Thanks, George & Tech291

Me, I just rewired my RS power mic so that it picked power form the radio I was using in on, which just happens to be an IC-706.

I had noticed Copper had the required battery, but "free" power seemed a nicer way to go..

Simon/Tech237,
Thank you for the advice. The battery is already on its way. This is on an old 40+ ch Midland 77-888, which is a back up radio to my other back up radio. Thanks Again

I use five of the 357 and use heat shrink tubing to hold them together.

I usually make my own too but they will lose connectivity after a while so you have to take it apart and clean the contacts.

put a dab of No-lox between the batteries and you won't have any problems.
