The battery works well and keeps charge better than the original battery

Fits and works perfect for my Costco motion sensor solar lights.

The sets of QOJH batteries I tested here surprisingly did quite well. The tested capacities actually matched the advertised capacity for once. This is very uncommon for an off-brand 18650. Usually they fall in the 50 to 66% range of the rated capacity. However, these were an exception. I also tested a 3000 mAh version of these batteries sold by QOJH and they tested out to only 1947 mAh (65%). Given the inconsistency, it is difficult to say if the next batch on 1800 mAh batteries from this supplier will test this well. Whatever you end up buying, try to stick to the reputable brands. Stay away from the off-brands if possible, especially the ones with high capacity claims. You've most likely seen 9900 mAh batteries advertised...the capacity of major reputable brands top out at 3500 - 3700 mAh. This should tell you something.

Received this 4 18650 rechargeable lithium batteries in a small box and batteries are shrink wrap and properly packaged. I tested all of them by using a charging device that measures milliamps and I got close to 1800 after discharging them once and charged to full. I am very happy with the results as I have bought fraudulent batteries in the past before. Since it is new, I am still unable to do the better testing which is to test for cycles as this is rated for 2000 cycles but that will take time and will update this review of it fails early. So far though it is living up to its name by lasting as good as your usual 18650. Being that this might be the battery of the future and is now being used with multiple types of flashlights and even the inside of most power tool batteries ( and not to mention EV batteries). I can see this being the future and I will be happy if I can use this for future devices but either way, this is a great addition to my flashlights.

The media could not be loaded. I have a great portable headlamp that I use for all my backpacking and camping trips - it utilizes the 18650 rechargeable style batteries, which are not easy to find and purchase my local shopping area. Also using one battery that the headlamp came with limits the amount of time I could spend using it outdoors. I was pleased to find this four pack 3.7 V lithium ion batteries at an affordable price and it will extend my usage in the evenings when I’m spending time outdoors - especially in the winter months when it starts getting dark around 5 PM. I can now bring these four charged up batteries with me whenever I go camping or backpacking especially when I tried to pack light and I have to carry a charger to recharge my electronic devices. Pros: batteries came pre-charged, long lasting, great prize for four pack Cons: None

1 out of 4 batteries work.

These cells are common in electronics. Often your lithium battery packs on tools, scooters and larger portable devices are made up of a bunch of these cells spot welded to each other and soldered to a battery management system. I got these to add power to a radio that otherwise used AA batteries. Plays good and loud on Lithium power now!

What factory? Who made this? What's gonna happen when they go nuke in whatever I put them in...? It's a high-risk item. They seem to work fine in my testing, but I'm nervous about leaving them in the charger, or in any device. Or in my house. They're bargain-priced, so that's good, but I don't yet know whether that's a good call until after a few weeks of use. In short: If limited to low-risk usage, yeah, get 'em! Else, be wary.
