I measured the capacity of these Shockli cells and actually got rated 650ma-h capacity! I'm impressed given the typical over-rated stuff found here on Amazon. (Amazon, review your ads! There are no 18650 Li-Ion cells above 3300-3600ma-h capacity!)

Hadn’t heard of this particular brand but I’m pretty happy with their performance. I use these for some solar powered post lamps and the performance has been great. I’m satisfied with the results and will be replacing the other older batteries in the lamps.

Don't make the mistake I did and get excited about a AA LiFEPO4 option for all your devices around the house. This item runs 3.2V-3.6V which is triple the voltage of a normal AA. You will pop your electronics if you use these like regular AA batteries. With that said, I did test these batteries and they seem to max on charge then drop to 88% capacity or so after 24 hours in storage. After that they seem to slowly drain a few percentage points day after day until settling in at 50-60% capacity according to my charger test reads.Some positives: These work great in the dual fuel Streamlight Pro-Tac 1L-1AA. Full charge to full drain was 1 hour on high beam. You get the benefits of 3.3V power even with diminished capacity. I find that fine for emergency purposes.If you have a three AA device you could get creative and use one of these batteries in lieu of three AA. With diminished capacity of course. I put one in my three AA chargeable radio and bridged the contacts.

Bought these batteries for solar lights and some of them work great and some don’t work at all or hold charge

These batteries didn't last even half the night, and now they won't recharge at all. I was impressed with the positive reviews so I bought 8 of them. Now I'm sorry I did. A waste of money.

The driver who delivered this item took the time to put the box in a non visual area. I've had boxes delivered just thrown on the porch. This driver not only made sure it was safe but delivered a great product from this company. Kudos to everyone.

All batteries were received fully charged and functional. They were the type and dimensions as specified.Longevity cannot yet be determined.

I bought these mainly to retain power to solar lights. What I surmise is, that like most batteries, they are prone to changes in temperature, which depletes the cells prematurely. I suppose it is what it is, but when they works, they work very well.
