ok to leave m9 battery charging for 2 weeks

It's a "smart" charger, as is the Lithium Ion M9 battery, so when the chip on board the battery reports full the charger reverts to trickle mode. If you live in a part of the world with a fairly stable power grid (unlike mine here in China) you should be alright.
I never leave my charger plugged in longer than overnight. Besides worrying about transients on the Chinese power lines I know that the Leica chargers and batteries tend to have a finite number of cycles and hours of life, and I try to get the most from both.

Any lithium ion/polymer batteries that is charged above their max voltage (even by 0.1v) can be permenantly damaged and catch fire. As such, pretty much every single lithium battery made for the mass market has some form of circuitry to stop charging once the battery reaches a predefined voltage (this is dependent on the chemistry used on the battery) but is typically somewhere around 4.2v. This is the same reason why you should never charge a lithium battery in a charger that is not spec'ed for your specific type of lithium battery.
