Thanks Volker, I am sure Eric will give his opinion if he decides to import
them to the US. It will be interesting.
Best regards
John

Hello John,
Eric Hiss of Rolleiflex USA posted some photos and information about the new
lithium batteries and the charger for the 6000 system on his Facebook site:

Very interesting Volker, thank you. I have seen something similar offered on
Ebay but from memory it was about 200 Euros complete with charger.
I have one question which would need to be answered first. The Nicd battery
packs are 9.6 volt, described as 10v on the pack case. The LiPol have 11.1v.
Would this damage the 6000 circuitry? I assume it has been tested.
The Rollei Power Interface -
https://www.bhphotovideo.com/c/product/224053-REG/Rollei_66269_Power_Interface.html
- runs on 12-18v and drops the voltage to 10v.
The 2000/3000 cameras used a pack with 5 NiCd AA cells - 6v. An empty battery
holder was sold which stated that only NiCd's should be used but people used
standard AA disposable batteries - 7.5v. This caused problems with the
circuitry - not all but some cameras were damaged.
There is a DIY tutorial at

a dead NICD-Battery with LiFePO-Batteries.
I have some packs which have been recelled with NiMh. They work in my 6008i,
which shows a charge level of about 2 on switching on, but on releasing the
shutter the display shows "CHARGE" and it quickly returns to a useable level.
After a few exposures the camera switches off because it believes the pack has
insufficient charge. The pack does still have 10v. I am guessing that the NiMh
cannot deliver the instant current demand required when the shutter is released
and the motor wind starts that the NiCd packs can. The NiMh have a much higher
capacity than the NiCd but cannot deliver the current as quickly. I am not
knowledgeable in such matters and I am sure someone on the forum will be able
to explain more comprehensively.
The power interface has a capacitor which takes a short time to charge from
slower release power sources but can give the instant current as required. The
power source should be switched off before the last exposure is taken so that
the capacitor is discharged after use - a LED indicates a fully charged
capacitor.
I have not yet tried using the 'quiet' slower motor wind setting (set via the
Master Control Unit) with the NiMh packs to see if that resolves the "CHARGE"
warning - it is on the top of my to do list when I next use the camera.
John

Subject: [rollei_list] New charger for Rolleiflex 6000 cameras
Hallo Rolleiflex 6000 users,
Marek Wiese of Wiese Fototechnik in Hamburg http://www.wiese-fototechnik.de has ;
developed a new charger (110-240V AC) and batteries using Lithium polymer cells
for the LensControl and Rolleiflex camera of the 6000 series. They have a
higher capacity then the old NiCad or NiMH ones and no memory effect any more.
I think that this increases the usefulness of the 6000 camera system. The new
higher capacity batteries can only be used with the new Wiese charger and not
with the standard Rollei like the current Type C. Old batteries can receive new
cells. The specification of the new Li-Pol batteries are:
• Li-Pol -3 - (11,1V) the current Nickel–metal hydride batteries have 10V
• 850mA
• AC 110-240V
• 150 x 80 x 40mm
• Weight 200g
• 2.5 h charging time
• new cells shall last eight times longer than the standard ones
• no memory effect any more
For more information please contact Marek Wiese directly on:
wiese-fototechnik@xxxxxx<mailto:wiese-fototechnik@xxxxxx>
Pictures of the new charger and batteries can be found on:
https://www.facebook.com/wiese.fototechnik
Kind regards,
Volker
