NiCad and NiMH:
The main difference between the two is that NiMH battery (the newer technology of the two) offers higher energy density than NiCads. In other words, the capacity of a NiMH is approximately twice the capacity of its NiCad counterpart. What this means is for you is increased run-time from the battery with no additional bulk or weight. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the "memory effect". NiMH batteries are less prone to develop this problem and thus require less maintenance and conditioning. NiMH batteries are also environmentally friendlier than NiCad batteries since they do not contain heavy metals (which present serious landfill problems). Note: Not all devices can accept both NiCad or NiMH batteries.

why can't some devices accept both ? think ur wrong there mate. to start with the voltage is the same and even the difference of 0.1 volt is not a problem. the greater capacity is most certainly not a problem. by the way a non rechargeble batery is 1.5 volts and both types of rechargegeble r 1.25 so quit worrying no problem.
