I need to replace the battery in an item I have. It's the quartersized/style
one. The way it is attached to the board, is via a clip arrangement that
you'd swear makes the battery removable. However, it is in fact soldered or
spot welded into the clip somehow. As a result, I'd rather not just cut the
clip arms to replace the battery as I'd have trouble getting the new one in.
This sounds like a PCB-mounted lithium cell. You buy the replacement with
the 'clip' spot-welded onto it (last one I got, I got from Farnell, I
guess there are Stateside syppliers too). You desolder the whole thing
from the PCB, then solder in the replacement.
The only possibility I see is unsoldering the clip from the battery, but it
strikes me as a rather bad idea to put a soldering iron to a battery.
I would not want to solder to a lithium cell. There is a very real risk
of it exploding.
