Hello All

Does anyone have a data sheet for the Ever Ready Winner grid bias battery (see the photo) showing the mA-hour capacity?

I realise that these batteries were intended for use where the current consumption was very small over a long time, but I've seen one used in the Denco MTO.1 modulated oscillator where the negative 3V cells were used to supply the filament on a DL92 at 50mA and the top sections supplied HT at 9V to the anode.

I was wondering how long the battery would last at 50mA discharge rate.

best regards ... Stef
