Capacity of various Duracell AA cells?

[Dave Plowman (News)]

A socking great single cell. Once used (amongst other things) to power
glowplugs for model engines.

Picture about a third of the way down.

Similar to cells once used for doorbells, etc, with a life measured in
tens of years?

How about the 4.5 volt lantern type with sprung levers on the top known as
'flat' batteries? Often used in cycle front lamps.

Incidentally, these are still available from the likes of Maplin and are a

They are, or were, used in a lot of headtorches and are often available
from camping shops. Saw Duracell ones in B&Q the other day.

Gosh, that's a big one. No, I don't remember those...

I had one of those for a model airplane. Everready, IIRC. Binding
posts on the top.

I don't recall the name. Any idea why they were called "flag"
batteries?

probably.... something about the top terminal rings a
bell, though.

Henh, good one! 8*) It looks kinda like a BC cell, but it's hard to
tell...

Ever tried carrying a few? ;-)

That's about the size of it. The 'flags' were little disks behind glass
windows in rosewood or mahogany boxes, used in large houses with servants,
if a bell was rung in a room, the staff could tell who rang it by looking
at the flag box. The bell would be mounted above, or beside the box, and
the flag battery (Usually a few in series) would be in the box or on a
shelf on the wall nearby.

Not even that large. I had friends in a three bed semi that had one!

Pah. I've got the remains of a mechanical bell system here. Dunno why -
you could have whistled for the maid...

How's it best to fit rechargeable cells into one of those
6V batteries with coil spring contacts on top?

Ever Ready 6V lanterns come with a rechargeable battery holder that
takes 4 D cells. It's quite handy, given the price of lantern batteries.
Now I've got a selection of rechargeable gel-cell lead acid lanterns I
don't need it so much.

A memory faintly stirs of something I read yonks ago. I think it might
be something to do with an old signalling system of the late
Victorian/Edwardian period - maybe railway related. The cells were used
in banks contained in wooden cases.

I distinctly recall such cells being used in an intercom system in my
primary school - it never worked, to the best of my knowledge.

And Barstow has plenty of switching tracks going on.
Actually Barstow is not at the edge of the desert, but it sure is high,
and many get high, but its not nearly as high as El Paso.

Alas, it's too late to correct the original author, whose ashes were
shot from a cannon not too long ago.
