4 Pack 18650 Rechargeable Battery Set, 3000mAh 3.7V Flat Top Battery with Storage Holder Case for Flashlights, Headlamps, Electronic Device

I use these for my vape mod and they are very good batteries. They charge quickly yet last a long time. Definitely recommend them.

Great. So far so good. They last long. Arrived as expected. Happy.

I bought a charger because my old one died, and figured get some batteries so I could get same day delivery. Well - you get what you pay for. At least I got same day delivery :)I use these in a single battery vape mod. They work OK, and they charge OK, and I use the flat top batteries (someone complained about them not being button head - read the description is all I can say). My other batteries are 3005 mAh - a whopping 5 thousandths difference - and they hold up for quite a bit longer. These don't seem to have capacity even close.So I don't really expect these to last long, and they don't perform like other batteries that are name brand. Maybe because no self respecting company would sell them? I won't buy these again. I knew better...

These replaced some old batteries in a tool and so far they are working great.

This 4 Pack 18650s has become a daily staple for me, especially in my vape devices. Overall, I'm genuinely impressed with their consistent performance for the price, earning them a solid four stars.The set comes with a convenient storage holder case, which is perfect for keeping them safe and organized when not in use. They charge up reliably and immediately jump into action. I've been putting them through their paces in my vape daily, and they deliver consistent power for my needs.Crucially, these batteries are far superior to Amazon Basics 18650s I've tried before. They handle the demands of daily vaping much better, providing more stable output and significantly longer runtimes than those alternatives.The primary reason for the 4-star rating instead of 5 is that, from my experience, they haven't quite held their charge for as long as some older, more premium 18650 cells I own. While they perform admirably for their capacity, those older, higher-end batteries still offer a noticeable edge in terms of pure longevity between charges.That said, for daily use, especially in a vape where reliability is key, these batteries are a fantastic budget-friendly choice. They're a dependable workhorse and a significant upgrade over many generic options. If you need a reliable pack of 18650s that perform well without breaking the bank, this set is a very strong contender.

Good quality

Batteries might work great for some applications but not in things that have a high-output draw (such as 50w draw) as they deplete too quickly.

batteries work great and have longer life then oem alternatives
