Steve, unlikely the Li-Ion bat will work on the 900.

The differences are

Voltage - 900 = 1.2v, NH1 = 3.2-4.5v depending on charge

Size - I believe there is slight differences and that the 900 battery is very slightly longer

Connections - 900 has posotive one end and negative the other, same as a normal battery. NH1 has 2 contact pads on the back of the battery

Capacity - 900 can have a capacity of 1400mah, NH1 has a capacity of 350ish mah (hope they release bigger)

There is to much difference for them to be interchangable

cant they just make a li-on battery the same size and voltage as the stick in the nh900??  

ah who cares - got the aa add on anywayzz...

For some reason, Li-Ion batteries are generally three times the voltage as Nickel Metal-Hydride.

Don't ask me why... >.>;

its all to do with the voltage diferential between the 2 electrodes. In a Ni-Mh the voltage between the 2 electrodes is 1.2v, in Li-ion its 3.4v

There is no easy way to make a Li-ion cell with 1.2v because that would mean changing the chemical structure & would probably make an even worse battery than a Ni-Mh is.

Li-ion is 3.6V. There is no such thing as changing the 'chemical structure'. A chemical is a chemical, the potential difference of the cell is a result of the electronegativity of the element or ion used as the electrolyte. You can't change the properties of the element that simply.

Either you ise Li-ion, or you don't. The only commercially viable options so far are Li-Ion, Li-Poly, NiMH, NiCD and lead acid.

3.6V x 0.380A = 1.368W

1.2V x 1.350A = 1.620W

for the answer to aeriyn, the gumstick and li-ion batteries differ in voltage because of similar demands held to different points. the gumstick is high-capacity but low voltage while the li-ion tends to be low-capacity but high voltage unsure.gif

Um, no shit. I said as much. I didn't know the actual reason why the batteries are designed like that. :whatever:

Try not to repeat yourself overmuch, kthnxbai.
