18650 Battery Charger, 4 Pcs Battery of 3400 mAh with Charger for Flashlights, Tactical Flashlight, Headlamps, Doorbells, Handheld Fan, Solar Wall Light, RC Cars

These are buttonless top 18650 batteries. They’re not quite 3400 mah, they’re closer to 2000 mah which is still respectable for an 18650 battery. So far these are working well for me in my little utility flashlights that I keep handy around the house. I did notice that my flashlights are just the slightest but dimmer with these batteries for some reason. They come with a charger but I already have a 4 bay smart charger so I haven’t used the provided charger. They seem to hold a charge well. Price wise, these were nearly the best deal I could find and there were enough decent reviews I felt I could trust they’d work well and they do. Just be sure you don’t need button tops for whatever you plan to use them for otherwise you might need to add a drop of solder or a rolled up piece of aluminum foil to make the connection.

I needed new batteries for my Mini-subox vape mod. Ordered batteries; the kit came with four batteries, two batteries cases to hold batteries (you really need these for the safety of the batteries and to prevent accidental discharges), and a USB single battery charger. I travel a lot, and this kit is perfect for traveling. I can recharge one battery either on a USB outlet charger or using my laptop USB outlet when I travel. The batteries are long life and give me 3-4 days of vaping before I need to replace the battery with a freshly charged one.

Bought these as backups for some fenix flashlights. They worked great in my older tactical flashlight but didn't work in the hm61r headlamp and no go.

This uses a USB port to charge. This can easily be charged at home with a USB base or off the computer or gaming system but it can also be charged in the car if yours has a USB port or a plug in for the lighter with a USB port, a power bank or battery pack. It's perfect for everyday use.The battery has a built-in safe circuit integrated system to help prevent the battery from overcharging, over discharging, short circuit, and overcurrent. Batteries can be reused and are a good helper for environmental protection so you keep batteries out the landfill hy recharging vs buying new and throwing them away

Instantly suspect when first handling, they are lighter than regular capacity 18650s which screams fraud. You dont get double, triple capacity batteries that weigh *less* than their counterparts of the same and size and chemistry.Sure enough, a fully charged battery lasted half a day on my vape. Likely 1000mah. Avoid this fake junk and anyone who sells it. I hate jumping through hoops to return fake junk.

The product arrived in a a day and already had a charge so I was able to use it right away, the charger is a good design and works well.

These charge fairly quick and have a long usage time. I have used these on both my vape and several flashlights and they work great.

I do not recommend these for vaping with Re-Buildable Atomizers (rdta rta rda rba). They do no have a high Continuous Discharge Current (CDC) , which is needed. Vaping at 30 or less watts, they do work for a couple of hours, so, useful in a pinch. Vaping at higher watts would probably drain them very quickly. My 3-STAR rating is based on that. If used for flashlights and other low CDC devices, I would give them 5-STARs. I made the mistake of not noticing that the description says "low discharge rate". Bottom line: if a description doesn't specifically have the CDC or CDR, don't bother. Look for a minimum of 20. The rating will be a number with a single "A" (not mAH)....20A, 30A, etc.
