Timely delivery. This battery charger with the digital readout is wonderful for quick read on the status of the charge , excellent product. Good value for the money.

So far... All (4) BATT's seem to have Excellent Life after full Charging. Though be prepared to await several Hours of Charging with Average Chargers. Not only do these BATTs last 2X longer than my previously purchased BATTs, they don't Leak, get Hot, or any other worrisome issues, so far, so good

Purchased these along with the other comparable brand names and one of the best smart chargers as I plan to use these more often. After the initial charge I immediately tested a brand name with these in the same exact headlamp. Both lasted far longer than any other 18650 battery I have dealt with and these outlasted the all brand names by a significant % (20% if I had to guess). These are comparable in price to the brand name when purchased in a single pair which is the only option for the brands but these can be purchased in volume making them far superior in both performance and price. I HIGHLY RECOMMEND these batteries!

The batteries were a perfect replacement in my rechargeable headlamp. Haven’t tested how long they last but they charged up fine and are ready to go find a downed hog.

these are great batteries. they arrive at about 50 percent charge; I do like this as it's the best state to store a lipo is at 50 percent charge. the first pic is a charge right out of the box showing they took about 50 percent charge. the second pic shows a full discharge cycle down to 2.99 volts. the third pic shows a full recharge after that discharge. ran this test 8 times and it was very consistent. these are true 3000 to 3300 Mah Batteries. I will be buying many more. So Many Batteries claim capacities they come nowhere near close to, Jesspow Batteries are the exclusion, great batteries

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.

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.

Put two of these in my UConsole from ClockworkPi, took literally 20hrs to charge that device. Since that is run in parallel means that the capacity is doubled, to a theoretical 6600mAh, and with mafs, I was in between 6000 and 6600mAh range meaning honest enough. Apparently you can go inside of Linux and boost the charging current, otherwise it defaults to 500mAh. WHICH IS WAY TOO SLOW. This definitely does the job and is honest enough about its capacity, that I can recommend them.ADVICE/WARNINGWhen shopping for these, anything claiming 3500mAH or more capacity is a lie, even with the newest and greatest improvement now JUST HITTING the market Lithium Silicone Graphene, the theoretical max capacity with that tech is about 5000mAh. You're paying more with these, since it's closer to honesty.
