Ni-Cd-----> Nickel Cadmium usualy of 750mAh(mAh stands for Milliamp Hour)
Ni-Mh-----> Nickel Metal Hydrite usualy of 2500mAh

NiCd costs around Rs 100-150 pp
NiMh costs around Rs 250 pp

the chargers for each is of different type..NiMh charger costs another Rs300 (maybe more)

if u have to buy for a digital camera, invest on a NiMh one!!
as NiCd wont last long! in my case..
Duracell lasted for 15 pics, Eveready 750mAh lasted for 15... and Sony CyberShot2700mAh lasted for 65pix

Ok that helped me a lot. My next question is how to discharge a battery manually. Most of these guides ask me to discharge the battery completely before recharging them.

some "good" quality battery chargers comes with dischargers. as they r quite expensive, you can connect a 1.5 volt bulb to the battery and it will suck the last bit of chemical energy left in the battery.
