3.6v vs 3.7v capacity?

I have noticed some sells are rated at 3.6 and some at 3.7. Is there a diffrence in capacity if both batteries are rated at the same mah and their both charged to 4.2v ??

Manufacturers seem to vary on the nominal voltage of lithium cells.

I suspect most Chinese manufacturers will use 3.7 as it's a bigger number than the other guy's.

There isn't actually any difference.

It seems that the lithium polymer cells tend to be rated at a nominal 3.7V - they can have much lower internal resistance than the cylindrical cells we are used to and can produce fearsome currents.


The numbers from my light tests are always to be found here.
