What is the mAH rating per battery?

I don’t know, but all these I installed were at 50% or less power upon install. Worthless

what is the expiration date?

I didn’t look but i did throw away half of the 2nd order

how many hours will these batteries last

It depends, not surprisingly, on what you use them for. On my bicycle computer’s receiver and sender two years, easily. In my bicycle LED lights, several months, but I always use them with the beam in flashing rather than steady-on mode. In any of our kitchen timers, forever.
