Hm...
Hy Nick-T, Hi everybody

I have a couple of older batteries I'd like to reset.
I tried the procedure described: Holding Flash & Menu buttons attach the Battery...
Nothing happens. No beep, no reset. Any idea?

Make sure you have your lens and viewfinder off!

Yes I know, thanx!

It can be a bit tricky to do making sure the two buttons are held down as you slide the battery on.. You're not by any chance trying to do it with the older 9.6V batteries are you? They can't be reset AFAIK

All Batteries are 7.2 V. And I'm kind a handyman, so handling a battery and pushing some nipples at one time is not such a big thing...   
Maybe it's the new Firmware?

Hi,
I have a maybe similar problem.
I loaded the battery with a different charger 2 times, because I needed the camera and had no right charger. It worked fine, but now the battery indicator on the camera shows 0% all the time.
Even when I charge the battery all night (with the original hasselblad charger)
Today I shot about 140 frames, with battery of 0% - as shown on the camera.

The reset, does not work for me, holding menu and flash buttons, clipping on the battery, but nothing happens.
I have H3dII-39.
What could be the problem ?
regards, Martin

Hi mMartin,
I have the exact same camera.
Did you try different sequences?
I do press the buttons first, keep holding it, than I slide the battery into position.
Worked for me.
Good luck,
Mauro

hi mauro, thanks for your tip
it worked finally, at least i heard the beeeping but the battery still shows 0%

[mauro risch]

Weird.
Try again charging the battery overnight, despite the blinking red light on the charger.
After that, repeat the reset operation.
I did struggle a few times, till I got it right.
At the end it saved me from buying 4 new batteries.
They normally last for over 200 shots each. Sometimes, 300 shots, depending on exposure length and ambient temperature.
Better luck this time mate,
Mauro

[Martin]

ah ok, I'll keep on trying!
Thanks Mauro!!

When, or how often, should one reset the battery chip??

[mauro risch]

I do reset my batteries when I feel it is not holding enough charge for more than 150 shots.

Upping this thread.

I recently have been having problems with one battery. Fully charged, put in camera, shoot maybe 20 frames, battery says it needs to be replaced. Charge, reset, charge. Same 20-30 frames. Repeat charge, reset, charge 2 times. Camera shows 100% battery. No shooting for a week, brought out camera today and cannot even power up camera. Does this mean its time to replace battery? Any other tricks?

Did you clean the contacts with ethanol ? it could be the problem, or maybe it's time to replace the battery !
