I already know that the AA lithiums last forever in my HC600. The downside is the cost. If I get some good Nihms, how often would they need recharged? I know that some run Sanyo enloops, has this affected thier performance at all in the flash department and what roughly is the recharging interval?

I'm just trying to determine what I should be buying as I plan on aquiring at least 1 more HC600 or PC800 in the future.

I use lithiums based on battery life alone as I didnt see the up side of buying rechargeables when I have gotten over 14000 pics on one cam and still have 75% battery life. Rechargeables would save money in the distant future but at 30-40k pics per set of lithiums I figured I could buy a set a year per cam. I use eneloops but only in my homebrews now because that does save alot of money in a short time and I think it would be alot longer before you would see a savings using them on a Reconyx. JMO

I use tenergy r2u nimh rechargeables in my 3 hyperfires and am very pleased. I normally don't run them much below 50% just because I might as well change them out when I have a fresh set with me. Still, I only change them out every month or two. I did run one of my hc600's over a mineral lick in the summer and came out with something like 9,000+ pictures over 3.5 months with the vast majority being at night, id guess 85-90%. I noticed no change in the flash from the first to last picture. The battery meter was reading somewhere in the teens so they still had life left but I decided to switch them out.

If you do go with rechargeables, make sure to get the low self discharge type like the eneloops, r2u, etc. You'll get more life out of lithiums, but I just hate the thought of throwing away batteries that still have life in them. My current setups have way more battery life then I would ever need.

I too can see that the lithiums last forever. Maybe I'll just stick with that. For me to get 14,000 pics I would have to have used it for 3 years at least....LOL

Sometimes I wish that lithiums could be bought in D cells. I get tired of recharging them.

I run lithium and eneloop AA's in my HC600s. I have feeders that with get 2000-4000 pictures a week with 30sec to 1 minute delay so I use eneloops at those spots. Other spots may only get a 5-10K pictures a year so use lithium AA's for those HC600's.
