Replace CR123 with RCR123

[PaulDalex]

Hello everybody
Some cameras, like the Minolta Maxxum 9 take two CR123 batteries. These are disposable batteries and have no load voltage about 3V. So 2 batteries make 6V
There are rechargeable batteries called RCR123 which have exactly same size.
I have measured 8V no load voltage for two batteries
The voltage under load will be lower of course.
Does anybody know if the use of the RCR123 would only make the camera more lively or just fry it?
Has anybody made the experience with the Minolta or any other camera?
All the best
Paul

Is the purpose to save money by using rechargeable batteries? The Maxxum 9 looks to be a camera with sophisticated electronics. I'm sure the increased voltage could make the motor run faster, but the concern would be if the excess voltage is enough to damage the circuitry. Even if it doesn't, it might throw the exposure metering off. Minolta no longer exists as a company, so it may be hard to find an official Minolta person who knows.

I think I would not do it!

Indeed!
It was just out of curiosity.
The aim is not to save money.
It would simply more handy to recharge instead of reordering

CR123 vs. RCR123... Beside the chemistry and voltage, the capacity and shelf life are different

CR123: Lithium, 3.0 Volts, 900-1400 mAh, long shelf life (up to 10 years)
RCR123: Lithium-ion, 3.6 Volts, 750 mAh

For a metered camera my personal choice would be CR123...

Thank you all for the input.
Shimokita,
yea I googled about the safety of using RCR123 and I found that link.
Very useful
In the end I wonder what is the point manufacturing rechargeables with such higher voltage
For the common AA and AAA it is just the opposite. Lower voltage

The market for these rechargables is so-called "tactical" flashlights.
(a) they drain a battery faster than a camera --> economic drive for rechargeables;
(b) their electronics is a current-mode driver for white LED(s), which, by its very nature, is insensitive (wihin reason) to the input voltage.
