RCR123A Reading 0 volts

[old4570]

Yes , you have heard this before , usually with a protected cell ..

I went through my RCR123A collection and sure enough a cell was reading 0 volts ..

I tore off the plastic sleeve covering the battery and sure enough the negative tab had broken on the protection circuit so there was no contact ...
No contact = 0 volts ...

I removed the protection circuit , and wrapped some packing tape around the cell , and now have a fully functioning non protected cell .

One could use some heatshrink sleeving , :thinking: , but I did it in packing tape .

Be careful, the B+ is just a mm or two from -B... very easy to short across this point with the heatshrink removed.
