Transistor Radio Battery

Post by Guest on Fri Oct 07, 2016 1:36 pm

I have been collecting "pocket sized" transistor radios recently and find that todays 9 volt batteries are slightly larger than those made years ago. When installing a new 9 battery in a Radio Shack "Flavoradio"  it's difficult to re-install the battery cover and near impossible to remove it without damaging the radio and/or battery cover.

The solution;

I take a pair of needle nose pliers and "peel" the metal battery jacket off. This is just enough to make the battery fit properly.

I still do not have a replacement for the round 9 volt battery found in many of these radios.  Sad

I have the name written down somewhere, but that battery company you posted about awhile back had the battery for my old VTVM and for the remote on my Concert Grand. I assume you checked there.

Great advice. I have many of these old transistor sets... some with the round 9V connectors, and some with even more obscure battery needs. Funny... it never occurs to me to operate them past the initial test. Wink

I believe the name is Battery Farm or Battery Barn or something like that. Mez is the one who turned me onto them. I got a weird 30 volt battery for my old Triplett meter and an Eveready 505 for my CG.

Mylar tape would make a good covering for the denuded piles.

Here is a link to the thread where I posted about a great battery website;

Well I tried the link myself and it looks like Battery Country is no more! Shocked

Bummer! That was a good place to get weird batteries.

I recently acquired a Tomb Thumb radio that requires two batteries (like old tube radios).

Battery A was a 45V with a plug like modern 9V batteries.  (Eveready 415, RCA VS 086, Burgess U30 or Olin 1909)

Battery B was a 4V that seems to resemble a modern D cell (General No 3RG3, RCA V499, Eveready E-233 or Mallory TR-233R)

I can't explain battery B, but, battery


A looked like a nine volt battery, But, clips were further apart, and, physically, the battery is larger.

They make a portable B battery that is a holder for several connected 9v batteries with a cover that looks like a period battery.  I use one with my portables.

here is a good like if you need a "B" battery for older tube radios.

Good info here for the transistors I own. Though, a while back I had the opposite problem. Bought an LC meter off E-Bay and the nine volt connector snaps are loose. Also, the battery compartment is slightly longer than it could be loose. I had to shove a piece of this cardboard tween the base of the battery and the compartment. This keeps the battery pressed hard against the battery contacts and all works great.
