I'm looking for a battery to replace the one in my Landis& Gyr C/H
controller, model RWB200; I thought it didn't have battery backup, but when
I took it off the wall there was this totally dead battery in it.

The controller is otherwise fine, and does all I want it to, so I'd like to
replace the battery, but I can't find any reference to it.

The cells are about 15mm diameter and 6mm thick, and in this case have been
heat shrunk and soldered (or something) together in series. I have seen
some in an old Maplin catalogue - single mercury equivalent cells; VQ76H -
that look right, but theyre not rechargeable.

I've no info on the controller - it predates me here, but it's a 2 channel
24hr 2times per day digital and seems pretty up to date.

Anyone any ideas on batteries that might do, please? I can't seem to find
anything close - RS have Varta button cells (can't give you the link, it's
one of their time expiring searches) which look vaguely right, but are
nowhere near the size.

TIA

You may find what tyou want on E-bay, but the sgggestion of getting some
cylindrical NEW Nicads and bodging them in is a good one.
