Over-volting microelectronics always reduces microelectronics lifespan, absolutely, 10 out of 10 times. As I said, you deserve what you get. Even if you get a decent lifespan, it means you could have gotten far longer without over-volting.
I just use inexpensive LiFe (Energizer e2 Photo Lithium) batteries instead. The resulting 6V is far better than 4.8V of NiMH (maybe 5.2V when the NiMHs are fully charged), making AF.C most excellent, without over-volting past the 6.5V max the K100D/K200D is rated for.
As long as you understand the trade-offs, it's your camera. I've still never seen a manufacturer create an user device for RCR-V3, and you still have not presented me with a single microelectronics user product that takes one by design (only stating who makes the batteries).
The "proprietary Li-Ion" reality of the world isn't a "trend," it's the reality as no vendor is going to certify their products for the great variances in Li-Ion implementations. There is no standard Li-Ion reference at all, and that's why.
