Well, it does a bit, Andrew, but (as this is a new machine) is this acceptable/expected that within a couple of weeks it's not going up to %100?

So if it doesn't reach a certain voltage while charging, it won't get to 100%. But this is only an approximate way of doing it, since the relationship between charge and voltage isn't linear - if you draw it it's more of an S-shape than a straight line. So don't worry too much unless you're getting unsatisfactory battery life, when it might need a new one... 18 months or 500 cycles is about as much as you can expect. It's normal for batteries to appear to have a higher voltage when they are being fast charged. This is because you're forcing electrical energy into the battery ... so the readout is the battery's energy plus the energy you're pushing into it.
