Can the Xbox 360 Play & Charge Kit cable charge regular Ni-MH batteries in the controller?

I use regular rechargeable Ni-MH AA batteries in my Xbox360 controllers, which I charge in a regular AA battery charger. Since the Xbox 360 Play & Charge Kit batteries are just Ni-MH batteries, just like the ones I'm using, can I use the Xbox 360 Play & Charge Kit cable to charge those batteries as well?

No. I tried, never worked. ----

The charge and play kit has circuitry in the battery pack that connects to the 4 pins in the battery compartment of your controller. The power connectors that the batteries connect to in order to feed the controller don't charge the batteries.

Unless you can get the appropriate casing for your rechargeables, it won't work with the charge and play kit.
