Hi all,

I realize this is a bit off-topic, but I figured with the number of  
engineers here someone might be able to help.

I'm (still) reviving a Jupiter 8. The backup battery is an obsolete  
Panasonic size, a 1/2A. It's a lithium, and specs 3V at 650 mAh.

I don't want to go digging for this obsolete battery size ever again  
in the future, and I'd like to find a modern equivalent with a  
similar rating that, preferably, I could find a PCB-mount plastic  
holder for (so I don't ever have to take it apart again to resolder a  
new cell). Is there a "most common" 3 or 3.6V lithium that's in use  
now that might fit the bill?

FWIW, the PC board solder holes are 25.5mm apart. I've got lots of  
room in every other dimension to play with.

Thanks in advance,
Eric

Hi

I don´t know the excact Jupiter battery, but lithium 3 V are very 
common batteries today. They are about half length of an AA an a 
little bit thicker. I work with film sound and in microports from 
Audio Limited you´ve got 3 of these batteries in the receivers.
So on a big film setup we´re using lots of these. You can try some 
film equpiment rental company or maybe a store that sells camera 
ascessories.

greetings

Gregory
