Energizer EL123APB2

Fitted as suggested. Good brand

Quite why such confusing name, no idea, but they are CR123A in my book, 3V lithium 10year life, that fits in my CR123A devices. Originally designed for digital cameras, now popular in alarm and security devices. Mine are used in motion detectors. Couple of reviews have commented on poor dates, robbing them of battery life, and voltage. Mine are dated with 9 years and 11 months left, so happy there, voltage looks good at 3.27V, my devices have powered up ok. But you will have to wait for longevity feedback, I'll comeback and update after "hopefully a year or so", if I'm back sooner, then probably bad news. But very hopeful at the moment.

Great price and high quality with good shelf lufe. Recommended seller

Not sure why just 123 is shown on the battery. By comparing the size and voltage to my old cr123 battery. This is really CR123. Later I may update the battery life after I have used it.

I bought these for a green dot laser sight, good fit and work very well and a good price.
