I agree, definitely DO NOT uprate a fuse.
Are you sure you have the cell block connected the right way around. I am sure
you must have if you have charged the pack. There is a thermister on the old
NiCd cells; are there extra wires for this on the new pack?
For the fuse to blow, the current flow between battery and camera must exceed
the rated current.
Did the fuse blow when you put the battery in? when you turned the camera on?
when you pressed the shutter release? I understand from your email that it was
as soon as you put the battery into the camera, but just to check.

Jeffrey,
Don't change the fuse rating or you risk frying your camera. I have had all my
battery changed to NiMh and kept the fuses, even the 0.8A for the SLX.
Somethings is wrong with the battery. The fuse is there to protect the camera
circuitry and I wouldn't risk damaging the camera.
HTH,

Hi!
I just bought a pack of the LiMH battery cells from eBay to replace my dead
NiCad cells. The replacement came quickly, and was installed within 2 shakes
of the proverbial lamb’s tail.
Charged it without incident. Plugged it into the camera and POOF went the
fuse. I still have (well, had) the 1.25 amp fuse in there. I’ve read that you
are supposed to up the fuse capacity, but nowhere can I find a value. Should
it go to the 2.5 ampere model? Maybe the 5 amp replacement? I know that these
cells have a larger capacity, but I am unsure why they would lend themselves to
a higher draw than before…
The cell, FWIW, is showing a full charge if you measure it against the unfused
positive. I am going under the impression that the guts of these batteries
aren’t fried since they charged well and it’s holding a 10 volt charge steadily
now.
Any insights or explanations would be appreciated!
