For those that have never seen them, allow me to introduce you to "The flag cell" (1st picture) They are like a "Torch battery" only much bigger, and were 1.4v (I think some were 1.5v ?) Some alarms ran entirely on these, no power supply, just a bunch of these in the panel. (2nd Picture) Over time when power supplies were used for the panel, they still relied on (What is now known as) End of line cells, these were often found in the most obscure places (Which always took ages to find) but were always to be found in these custom-made battery box holders (3rd Picture) The pictures are not all from the same house, but there was one person who refused to upgrade her alarm and she used to supply the batteries for us, and no, we are not talking late 70s, one was still working in 2001 (When I took the picture) Believe it or not, these cells are still made today (2022) and they are £17.40 each
