Deserves MORE than five stars!!!!!
I've bought other brands of 18650 batteries, but these a by far and away the best ones to date! They come with a 50% charge (perfect for storing this type of battery), and they don't get weaker as the battery power decreases like so many other 18650 batteries do. They provide about the same amount of power when they're have a 10% charge as they do when they have a 90% charge.

More than satisfied
I decided to try these for flashlight use since the previous vendor I use doesn't seem to exist anymore (those batteries have served me well since 2018).First off, beware of any vendor with ridiculous capacity claims. Also there are lots of horror stories of subpar rechargeable batteries when purchased on line.These batteries have a claimed capacity of 3300 mAh. After complete charge (they arrive at around 50% charged, ideal state of charge for storage) the were all in the 3100 to 3200 mAh range and stayed cool during charging. After a few charging cycles I'm sure they'll be up around the 3300 mAh range.I definitely recommend these.

More like 3000mAh
I tested these on my VC4SL and found them to have capacities in a range from 2988mAh to 3133mAh. I measured the capacity of 8 of these batteries, the mean(average) capacity was 3021mAh. This isn’t bad but it’s not the 3300mAh they claim, the highest was 3133mAh. These batteries are button top and have a protection circuit. They have pretty high internal resistance averaging 70 or so milli-ohms. I tested the max amp draw for these to be around 8-10amps continuous. They have an ok voltage discharge curve, they don’t see any issues till after 50% discharge where the drop off becomes somewhat steep.All that aside, they are fairly inexpensive and arrived very quickly. They work well enough for most applications, but suffer V-droop in the cold. Battery life is good, but not as advertised. They seem to be reasonably durable, not sure how long they will maintain their performance as only time will tell.

Terrific, best I've found
Fantastic batteries. They last quite a while, even with heavy use. Very pleased. Will buy more.

Shining Bright for A Long Time
I have used so many different rechargeable batteries that just do not perform as described. There are many that over state the mAh's and do not last over 20 recharges until they start going weak in 15 minutes. These have surpassed my expectation's as I have never bought this brand before, but to my surprise these work GREAT. I waited until I used these for several weeks and they still are holding the charge when using them for a long time close to 1 hour on MAX Power on my headlamp set which to me is incredible. The one thing you have to get used to is the recharge time. They take longer than those Cheap-O's but that is to be expected on a True Quality Product. I will buy more as needed That's A Fact Jack...

A little too wide ...
I'm trying to find some quality 18650 batteries for my headlamp.These appear to be quality batteries, based on the reviews and their heft compared to the batteries that generally come with flashlights and headlamps.However, they are a little too big--they don't fit in my headlamp's battery compartment. I've run into this before, generally the batteries are too long, as though the manufacturer slapped a button on a flat-top battery. Not the case with these, they're simply too wide. About 0.5mm, according to my calipers.A bit flabbergasted that there's so little extra clearance, but at the end of the day, batteries made to the 18650 spec fit, and these don't.

Price didn’t break the bank.
Not bad. Average battery longevity.
