I started down this same road the other day. Actually, the nicad pack in
my phone wasn't dead - it was just real old and wouldn't hold a decent
charge any more. My local Circuit City wanted something like $19 for a
replacement pack. I considered that outrageous, and decided to
"restuff" it with three new nicad cells. As I was getting ready to
leave Circuit City, I noticed a cordless phone on sale - for $7! Not a
wonderful phone, but guess what was inside it? The EXACT SAME battery
pack that was selling for $19 on a bubble card on the other side of the
aisle.

Needless to say, I didn't pay $19 for the bubble card pack, and I didn't
rebuild the old one ...

Hi

Rebuilding what I thought was a dead NiCad pack for a cordless phone.
The battery pack in question is a Sony BP-T18 - 3.6v, 600mAh. In series
connecting 2 of the batteries is an open component with these markings:

bel 2A
MO 125V

I can't i.d. it based on the markings. It kind of looks like a small 1
amp rectifier diode, as far as size and shape go, but there is no
polarity marking on it. I think it's some kind of (blown) fuse? I've
never seen this in a 3.6v phone battery pack.

If it is a fuse, why would they put one in a simple nicad battery pack
for a cordless phone? Is it safe to just bypass it? I do have a parts
source for micro fuses with leads. (Which look quite different from this
one, but would fit.)

If it isn't a fuse, what the heck is it?
