Cool.

It should - the profiling code is specifically designed with
multi-battery (different capacity) batteries in use.

Sure. Have you let it self-profile? It needs a few (4?) 0% to 100% to 0%
charges to get a really accurate result.

Sure, we don't read those keys unless the accuracy is really bad. You
build up accuracy just by using the laptop - you can see this in
gnome-power-statistics.

Could you post your accuracy and time graphs so I can check it all looks
okay? Thanks.
