I have read up on Jonas' posting on rechargeable CRV3's, and other posts saying to make sure they are voltage regulated. I want to satisfy my curiousity with 3 questions.
Search the forum database over there and you will find the answers to your question. And I made one of the very first lengthy post on my experience of using RCR-V3 on my *ist D (and comparisons with CR-V3 (no difference here), AA Lithium and NiMH, too)
1. Anyone use them in their K100d?
I am using both RCR-V3 and CR-V3 in my K100. However, I still do not use my latest Sanyo 2500 mAh NiMH as they still perform poorly in my K100D.
2. Anyone know of a reliable source in Canada?
Just search for the specified voltage rating. My RCR-V3 marked with 3.0V rating. To place safe, do check if the manufacturer dares to mention about voltage regulation for their battery.
After you get your new RCR-V3, do remember to measure the voltage for a freshly charged battery. Mine measured at 3.4V (same as one-use CR-V3 when new).
3. Do rechargeable CRV3's leak power like the NiMH's over time?
Nope. It's Li-ion or Li-polymer batter which the self discharging rate is very low.
Also, other RCR-V3 advantages include:-
1. Longer battery life than *any* NiMH;
2. AF will as fast as CR-V3 (Vs the particular sluggish AF for NiMH);
3. Battery indictor will show correct Full, half-depleted and fully depleted status, unlike those NiMHs which defeat the function.
In short, with a proper high quality voltage regulated RCR-V3, you can enjoy the performance and stability of CR-V3 but it is rechargeable!
Good luck!
