THE BATTERY VOLTAGE ON THE Olympus BLM-1 battery is 7.2V,.... and The DC input voltage on the camera for external powerr supply is 6.5V..
Some external battery packs are rated at 7.2V
I already called up one website selling battery packs and they admitted the error and they changed the info immediately.

specs are based on a wide range, 6.5, 7.2 7.4, you can use them all, no damage done... minor issues, should not be concern at all.

I've use several battery packs rated @ 7.4 v for the last 4 months...works like champ.

Oh really ?
ARE WE TALKING ABOUT THE SAME CAMERA ???????
Have you consulted with your local electronics shop ?
I'm not talking about places like Radio Shack....nothing wrong with thier quality but I mean places where electronic " geaks " go.

I'm trying to understand the problem here...what battery packs?

Is something mislabeled, wrong voltage?

As for the geek perspective, most likely there's a voltage regulator in the camera...other C-series cameras also require 6.5v DC external input, but they run on AAs which is a maximum of 6v alkaline, or 4.8v NiMH. It's obvious that the camera can run on lower voltage than supplied, so there's already a regulator to reduce the voltage...and many regulators can accept a higher voltage than they are rated (for instance, the common 7805 can have up to 35v input and its output will still be 5V; below 5v input and output voltage follows input voltage).

If you're really paranoid, stick a diode (not resistor)in series and it'll drop the extra 0.7V, but as the above poster mentioned, the camera likely contains a voltage regulator whichwon't evensneeze at a 0.7V differential.

PAranoiD what.......and you say the camera most likely contains.....well is somebody going to spend a thousand bucks on a camera to guess if it's LIKELY TO CONTAIN A VOLTAGE REGULATOR which I'm sure it has............. but how much abuse could that voltage regulator take when it evetually overheats and then a trip to the repair shop ..waranty void.
Oh my goodness

HELLO I'm just alerting other C8080 owners of the possilble risk of using a higher voltage battery pack.

Thanks for your feedback ....any other electronic geaks out there that can throwr in thier IMO ?

Hello Mikefellh........
No nothing is mislabled on the battery pack it's what some websites state on the compatibility of certain battery packs. The Digipower DPS-9000 with the C8080.

1. I'm with everyone here as well... The camera got to have voltage regulator! Thoses micros need to run at much lower voltage ie 3V or less and even 1.8V in order to last hours on end. Beside the batteries voltage do not stay constant throughout their operation and need to be regulated!

2. To be efficient (in order to run all day) theses regulators are the switching type, and not linear kind so they don't heat up by sinking the extra voltage. More likely the regulation is done by "ON" and "OFF" cycles and the camera actually runs cooler with the higher voltage by being more "OFF" than "ON". :idea:

3. Manufacturers tend to "spec" this so you're lock into their own accessories: The Minolta D7 (a battery hog) used to be spec'ed the same way, but their own external battery pack are rated @ a higher voltage (and even higher still when fully charged). :-)

Beside "if you're really paranoid, stick a diode (not resistor) in series and it'll drop the extra 0.7V" ... not any diode though the RadioShack geeks can tell you which one which can handle the current.

John,

Your advice is well noticed, but really, it's not any concerns over this issue, as I said, the camera can handle a range of rated voltage, a slight different in voltage is not gonna hurt your C8080WZ. So don't worry about the battery will fry or bollow up your camera, unless you intend to put it over the top of a cooking stove of try to deep fry it.

Let move on...life is good...no more paranoia and whining...:?
