Anyone using theirs with rechargeables?

I need backup batteries for my body, and it seems like the 900mAh cr123 li-ion rechargeable batteries should give me more capacity than the standard battery grip. It would also allow me to have several sets of backups for a fraction of the Hasselblad price of replacement battery grips.

Searching forums seems to show some reports of the standard CR123's not lasting very long in the grip. Doesn't really make sense to me why a nice li-ion rechargeable wouldn't be good, but possibly I am missing something.

Experiences?

Im curious of the same thing. Surely someone has tried it.

I bought some rechargeable cr123's off of Ebay last month. They do seem to be lasting longer than normal cr123's. I've put about fifteen rolls of 220 through my h1 and it's still showing full charge on the LCD.

I've been looking for a setup like this. The problem is that I haven't found a charger that will accomodate the 3 necessary batteries for the H1/2. The only chargers I've found are for one or two batteries. This obviously works, but it makes charging a pain in the a**. You would need at least two chagers (2 battery) for charging just one set.
Is there a charger that will do 3 or more batteries in one go?

You are right about the lack of 3-4 battery chargers, but this seems like a non issue, at least to me. The rechargeables would be backups, li-ion cells hold a charge for a long time, so I would just own 6-9 batteries, charge them up in rotation, and recharge them when necessary. There is certainly a lot of computer time I put in, and swapping out some cells here or there isn't a big deal.

Anyway, I am looking at something like this..(just an example, similar products available elsewhere, no experience with this company, etc, etc)

The Hasselblad 7.2v battery has an 1850 mAh capacity. Shouldn't 3 900mAh batteries provide substantially more capacity (2700mAh)? Is there some difference here I am missing?

Once you start looking at hasselblad prices this seems ridiculously cheap and very useful.

CR123's are 3V each. The CR123 configuration puts out 9V. The three cells, connected in series, still give you 900mAh.

If the cells were connected in parallel, the capacity would multiply, but the voltage wouldn't.

To get 9V, 2700mAh, you'd need nine cells in a 3x3 series-parallel configuration.


-H.

Last week I bought some li-ion CR123 rechargeables (from 7dayshop in the UK), gave them a really long charge first off but they simply dopn't power my H3D39. The camera starts up ok but as soon as you fire the shutter, it closes down, clearly lacking power. It's fine with normal CR123 batts, ie, non-rechargeable, although battery life is pretty short. I bought six rechargeables but neither set nor any combination powers the camera. I wonder if the batts are all faulty or if there are more powerful rechargeables available?

Edit: NicholasR - just looked at the link in your post and my setup looks identical except for the labelling.

You may need to get yourself a professional charger instead another black brick. This way you'll charge and condition any of your batteries. You need to solder your own leads but that's easy.

Great system!

Ahah! Exactly the information I was looking for. Apparently I slept through that day at school. Makes prefect sense. Thank you!
