rechargeable batteries failure

Hi, bought a set of 4 'Ansmann' 1800 NIMH in UK about 1 year ago, 2 of the
set are OK but the other 2 had died on me after only about 12 charges. They
appear to charge on charger but won't even take 1 pic before dying. I have 6
batteries all told so usually rotate all 6. so they have not been over used.
At the moment they have been relegated to my TV remote where they are
working.
I use the batteries in Fuji 2600 Zoom.
Any ideas out there the reason they should be dead for the camera, I know
the camera uses a lot of power but they shouldn't have died already should
they ?

A battery has an internal impedance. That's a measure of its ability to
deliver a specified current. A high internal impedance battery will power
devices with low current demand but not devices with a high current demand.
A battery defect can raise its internal impedance and make it useless for
high current applications but it can work with other devices.
