LI is better. And also NIMH does not have enough power as LI. LI is very powerful and will last longer than LI. LI is better in many things so it will work.
For any digital camera a Li ion battery is better than Nimh because it holds more charge and does not lose its charge nearly as fast when the camera is not in use.
The NiMH battery is better,but it's more expensive.
No.
nickel metal hydride; slightly higher voltage than Ni-Cd (Ni Cad, or Nickel Cadmium) and better for high current/high draw applications. Pre-2005 NiMh batteries had a higher self-discharge rate than those of today, which are typically purchased pre-charged. Li-ion (Lithium Ion) is probably a better rechargeable battery all-round.
They used to be either Ni-Cd or NiMH, which made the cell voltage 1.2V. These days they can be Li-Po / Li-Io, which have about 3.6V cell voltage.
You can replace a Panasonic NiMH (Nickel-Metal Hydride) battery with a similar Duracell NiMH battery of the same size and with the same voltage and power output.
NiMh batteries perform better in high discharge devices (like digital cameras) than alkaline batteries. They are also rechargeable, unlike alkaline batteries.
If it will physically fit in the space, then yes, the 2700 mAh battery should work fine.
Provided the batteries are the correct voltage (You shouldn't have to worry about this, as an odd size battery won't fit, though it is worth mentioning) and chemistry it should be OK. A NiMH charger should be OK on all NiMH batteries, but not for Li-Ion or other types.
they are the same duhhh
It is NiMH, the only type available.
Depends on the cell/battery chemistry. The most common voltage for a cell is 1.5V, but you can have anything from 1.2(Ni-Cd, NiMH) to 3.7(Li-Po, Li-Io). An automotive battery cell produces 2.2 volts.
