Default Re: Sourcing batteries/cells thought to be obsolete.

The Ever Ready twin cell 3V 'cycle lamp' battery is in fact two large F cells, four can be found in one of those 6V square lantern batteries, I have not tried making this one up yet. The U14 was a fat battery and was used for those gaslighters, again these were 1.5V but they had a screw thread.

The U8 can still be found, that is if you can get the No.8 as it had two of these inside. The new code for the No.8 is 2R10. I am not sure if these have two cells in now though. Most hard to get batteries can be made up or are found in modern batteries but for test equipment it has to be a certain capacity. If an AVO meter did use a U10 I would think one cell out of a 1289 would be ok for it providing it was zinc-carbon. These batteries are made in alkaline form too.
