18650 Rechargeable Battery 3.7V 9900mah High Capacity Long-Lasting for Flashlight, Toys and Pathlight 24-0717-3S (Button Top, 2 Pack)

These are a stronger amp hour rating than most. I appreciate that. And I really like that they are rechargeable. I have used them for only a short time, but they seem to be fine. They were a good value.

Good life after full charge! Recharged 3 times now and still does very well. Flash lite is used nightly for about 20-30 minutes per night. Recharge after about 10-12 days. We had to purchase the CWUU 18650 Battery Charger because we couldn't find a these particular battery's that came with it's own charger.

This type of seller doesn't care if this battery cell blows up in your pocket or handbag. Cheap cells don't last long, poor output, more likely to have a reaction to charging or dropping.Most 18650 cells are made in one or two places in China. Some cells are great and the high-end ones get sold to companies like Panasonic ... the 18650 cells that test poorly get sold to companies like this one. They are bad batteries and should never been sold in the first place. You have been warned.One 18650 cell on a full charger at 4.2v will burn for about 2 to 3 minutes like a crazy welding torch, burning everything in sight. You can't put a chemical battery fire out. It burns till the reaction is complete.It is a very bad idea.I'm a very experienced person with Decades of experience with battery charging. I ordered a set of them to test. I ordered the over two weeks ago. Still hasn't shown up. That means they are coming straight from that wonky China cell factory that should be disposing of the bad testing cells and not selling them at a fraction of the cost. And we think we are getting a great deal but in fact, you're getting a little bomb waiting to burn down your home. This is not a joke by any means. Please use reputable battery company for your 18650 needs this company is not it

These are actually very reliable, I've had them for only a few days. They work great for my vape, doesn't require any real upkeep or anything. it's a hit and miss with them coming charged or not. I got a hit on both of them, they were both almost fully charged. I haven't had any issues with them so far! Thank you so much for providing this product at an affordable price! (It even arrived sooner than expected!)

Does well performs excellent

Once your battery gets to around 30-45% they will just immediately drop to 0%. On top of that 1 of the batteries won't even hold a charge at all. Update: They are not safe to use I have 4 dead batteries now and one overheated while in a carrying case. Don't waste your money on this. There are better brands

These seem to be good batteries. Work in my Tac LED flashlight very well. Two for less than $15 is a good buy. I haven't used them long enough to evaluate their life though they already seem much better than the old battery they replaced. The description in the invoice says this is a 9900mAh battery. IT IS 3200mAh. Question any listing showing 9900mAh capacity. I am certain the CWUU was advertised as 32oomAh when I ordered it. It obviously is not.

Had to modify the wiring to a yard lamp but once these got charged they light lasts all night.
