Only if your laptop battery is 1.5V instead of ~12V (typical from back when they were all NiMH, not real sure what voltage they stack Li-ion cells to). I guarantee they're NOT 1.5V, though.

TANSTAAFL. Did you really think something that's smaller than your laptop battery and costs less would give better performance?

But as drizek points out, a 1.5V cell's a 1.5V cell, so substituting C or D for AA or AAA cells will work. Substitute parallel gangs for single cells if you need more...
