DEAC used in Kofferradio (German Portables)

Dear fellow members,

The DEAC is an early German / Varta NiCd type battery. Many of the Mid 1950s to 1960 "Röhre Kofferradio" Valve Portable Radio seem to have large rectangular DEAC.

What was the Discharge capacity at the various filament currents?

Can I presume any such cell from 1955 to 1960 is beyond use, defunct, not recoverable?

Would  a 10,000mAH NiMH D cell replace it or would it be overcharged? many NiMH can't be left on trickle charge once charged.

It seems often the DEAC is used also as voltage regulator while on mains. How is safe mains operation possible with defective ancient DEAC? Or without DEAC?

I don't post this with the Model I'm working on as I think it's general to all this kind of German Tube Portables.

Perhaps the UK was more dominated by Vidor and Ever Ready Batteries and their Radios and this why the DEAC isn't seen.

When you search Google it asks "Did you mean dead battery?"

I find the DEAC D2 was Charge at 200 mA for 14 hours, suggesting perhaps 12 hours operation. with D*96 generation filaments and maybe 6 hours with D*91 generation filaments? 

Is there much differences between D2, D3 and D3,5?

D2 is Dimensions (WHD) 34 x 60 x 34 mm / 1.3 x 2.4 x 1.3 inch

D3 not listed

D3,5 is Dimensions (WHD) 35 x 77 x 35 mm / 1.4 x 3 x 1.4 inch

The UKW-Koffersuper LD452AB  uses "DEAC-Zelle D3 (Heizakku)", which my main interest.

if I am more concerned with safety and no leakage and less concerned with Original appearance should I remove the DEAC?

Yours

Michael

In my Klemt Antennentestgeraet AT 200 M belongs a Deac D3,5 Akkumulator.

The schematic diagram can be seen at the model-page.

The heating current is 275 to 325 mA. I think that the celltype 3,5 means 3,5 AHr and that charging/discharging current must be about 10 %, or 350 mA .

In the user manual I found that the charging time of a total empty cell is about 15 hours with the equipment switched off, but still connected to the mains.

In my AT 200 M this cell was missing, so I have replaced it with a 4AHr nicad-cell.

This works without a problem.
