nice batteries
I like lithium batteries. Easy to charge, my tester says they are full. I put these in smoke alarms, so we will see how long they last in that role.

Rechargeable 9v with spares ready to go
I purchased an earlier version/brand. These are upgraded bottom glows red on charge and goes green when complete + Also the four usb 2 type is better. Power seems good but too soon to tell. Im using them for smoke alarms

DO NOT WORK
They discharge when not plugged in to anything. They only work immediately after being charged.

Cold will drain fast
Work ok, but it took about an hour and half to charge. And in the cold, they drain fast

Will take time past warranty date to evaluate recharge capabilities.
As described and so far works well. Keep in mind if you don’t use all the batteries at one time you won’t be able to determine the overall recharge capability.

I think the capacity is really small, not super impressed with them.
Not particularly impressed with these. I tried them in smoke detectors and they lasted for a FRACTION of the time of a real 9V battery, even after a FULL charge - not even 3-4 months in and I already have to pull them down from the smoke detectors and re-charge them. Is it worth it? You decide. But for me, a real 9V in a smoke detector can go for 2 years (until it beeps and complains) ... So make that call yourself. I think I'll stick to regular 9V batteries (at least for smoke detectors).
