Chirs, No, actually, I need both. They used the mercury battery over its ability to hold the voltage steady over its charged cycle, which was something they did pretty well. It's a shame they've really not made anything to match them yet, except I've heard of folks using Lithium in their place. I think when they banned mercury cells, it helped with the slow death of Burgess battery, since they produced a good majority of them.
The only battery supply that wouldn't have had good regulation, would have been the 3 volt supply using the two AA batteries. The 7 volt, and the 24 volt both used the mercury types. Actually, I think they used 12 and 24 Vdc off the two large mercuries, using the center tap for the 12 volt. This is the supply for a very precise Vishay bridge measuring network. They used a standard line power supply for everything but the supplies feeding the bridge itself. The batteries gave a clean supply voltage, and the mercury type batteries gave the regulation over standard carbon, etc.. I'll take a look at the link on the supplies, and thaks for that.
