These JESSY 18650 rechargeable batteries are a solid upgrade over disposable options for flashlights, small electronics, and other gear that uses this size. They hold a good charge out of the box and recharge reliably without getting overly hot or acting unpredictable. Runtime is impressive for regular use, and they seem to keep their capacity well between charges instead of draining while just sitting in a drawer. The build quality looks clean and consistent, so they feel like something that can be trusted for devices that matter in daily use or emergencies. For the price paid, this pair offers very good value compared with constantly buying one-time-use batteries. Overall, they are convenient, economical, and a smart choice if using 18650-powered devices regularly. Read more

I originally purchased these batteries believing they were solar. They powered my string of solar lights for at least four days, which shows they have excellent capacity. When they stopped working, I gave a low rating, but after contacting the seller, I learned they are rechargeable batteries, not solar batteries. The seller was very professional, replaced the batteries promptly, and even told me to keep the replacements. While they’re not suitable for solar use, they’re great rechargeable batteries, and I truly appreciate the seller’s professionalism and service. Read more

Test verifies battery capacity is 3000mAh as advertised. Dimentionally accurate. Works perfectly. (This is a breath of fresh air given the vast number of other battery products that make fraudulent capacity claims. Thank you Jessy..) Read more

These 3.7-volt rechargeable batteries work great and hold a strong charge. They recharge quickly and last a good amount of time between uses. Perfect replacement for many small electronics and flashlights. I like that they’re reliable and save money compared to disposable batteries. So far, they’ve performed just as expected — consistent power, no issues with overheating or draining too fast. Great value for anyone needing dependable rechargeable batteries! Read more

These batteries were exactly what I needed. The information given by the vendor was very explicit. If you ordered these and they don't work for your intended use you have nobody to blame but yourself. I wish more vendors were this detailed in telling you about their product. It sure would save a lot of returns. Read more

These batteries are great! They last a long time because they are 3000 mAh. They are also great that they have the nub on the end(button top). I love that they have a 1 year warranty and I highly recommend them! Read more

Not a true 18650 battery, the length of the battery I received is 652mm which I suspect is the function of the added button top. Unfortunately for my application that extra 2 mm casuse the battery not to fit in the battery compartment. Also when measured with calipers the diameter was 19mm vs a true 18mm. Otherwise I would give this a five star review. Read more
