JESSY 6 Pack 18650 Rechargeable Battery Flat Top，3.7Volt Lithium Batteries 3300mAh High Capacity for LED Flashlights, Headlights, Small Fans, Toys

I recently purchased the 6 Pack of 18650 Rechargeable Batteries (3.7V, 3300mAh), and they've been a reliable power source for my devices. These batteries are perfect for a variety of gadgets like LED flashlights, headlights, small fans, cameras, and toys. The 3300mAh capacity offers long-lasting performance, meaning I don't have to recharge them frequently. The flat top design fits well in most devices, and they hold their charge effectively even after multiple uses. If you're looking for durable and high-capacity rechargeable batteries, this pack is a great option for powering your everyday electronics!

Not bad battery for price. Some decharge quicker then others overall satisfied

A+

Purchased the 8 pack of these batteries and started using them in flashlights and vapes. By the time I got around to using all 8 batteries, more than 30 days had gone by and it was at that time I discovered that 2 of the 8 batteries were dead. As in zero voltage. And being zero volts my battery charger wouldn’t recognize there being a battery in the charger, so they won’t charge. I didn’t want a refund since the other six worked just fine. I wanted the two dead ones replaced. And since it was past the 30 days, this company or Amazon wouldn’t replace them. I get it, it was my fault for not checking the voltage on all 8 when I first received them. But you’d think a company that sells batteries might check themselves before shipping, but apparently not. The batteries that do work, work fine which is why I’m giving 3 stars and not 1 star. Next time I’ll know better. Bottom line, check all your batteries before thirty days so you don’t wind up keeping brand new batteries that don’t work.

It works spectacularly well, recharges just fine, and I have no complaints.

Seem to be good batteries. I have no way to test the mah, but the time it takes them to charge, and the weight of them makes me believe they are close to their rated capacity. They do last noticeably longer than others I own.

These are nice quality, and I use them in projects and flashlights. They aren't 3300mAh, but that's no big surprise. They are around 3000, and that's not bad as far as an 18650 goes. The build quality is good, and I can feel nice about giving somebody a flashlight with one of these in it versus some battery pack pulls. I like them, but I do wish these companies would stop lying about stupid things that can be easily checked.

I received this pack of 6 18650 batteries and immediately used one to replace a battery that was past its service life. The replacement has been great for four months so far. No problems. Since then I used a second one of these 18650s. I think it has been in service 2.5 months. Again, no problems at all. I'm pretty happy with these batteries.
