What is the amp hour rating and what discharge rate is used to determine that ahr rating?

I believe these are 1200 mAh. We use a lot of lithium 9 volt batteries at my company so I did capacity test. Unfortunately, my battery analyzer had an error and didn't complete the test. At the time of the error, the tested capacity was 942 mAh and the voltage was 7.49. The discharge setting was 0.25 amps. I may do another test in the future but since these are primary cells you have to waste a battery to do the test.

Anybody know how these compare to Energizer brand? I've always had issues with off-brands not performing as well so I spend the extra $ on name brands

I've had these in place for 2 years now on digital door locks (barn and garage - no heat). Northern Michigan can get really cold in winter and standard battries have failed on a few occasions at very cold temps. So far these have not failed. As to longevity I can't give an experienced answer.
