18650 Battery Charger, 3400mAh 4 Pack Batteries for Flashlights, Tactical, Headlamps, Doorbells, Handheld Fan, Solar Wall Light, RC Cars

I got these as off brand replacement batteries for my Huni-badger. Worked very well, fast recharge. Can also charge in the official Huni-Badger charger.

I use a gymbal for recording videos. Even though my current gymbal is supposed to last 12 hours on a full charge, I typically get about 2 hours of actual battery life. I ordered these replacement batteries so I would have extra to use for recording. They work great and with 4 batteries I don't have to worry about recharging all the time as well. I also like that they come with 2 cases to hold the batteries as well. I toss them into my backpack and don't have to worry about them bouncing around or getting broken.

Works great, does need recharging every week. The only reason I didn’t give it 5. Stars is because the cord is kind of short

I have couple of flashlight as well as night vision binoculars that use these 3.7 batteries, which are not very common batteries that I can pick up from local supermarket or office supply stores so I got this 4 pack batteries that comes with a charger. These are high capacity 3400mAh batteries and worked without any problem with my flashlights as well as night vision binoculars. It's great to have these extra batteries charged so I will have spare ones to replace when the current battery is drained, especially when I'm outside or at camping. The charger works great and it can be plugged into any USB port to use the charger. The charging light indicator changes from red to green when it's fully charged. It would have been awesome if the charger can hold and charge 2 batteries at a time but can't complain about these 4 batteries plus charger at such a bargain price. Highly recommend it to hose who need this size battery.!

Not sure how this company determines capacity but it is wrong. These are around 1500 mah and not even close to 3400. I tested on several devices and results are pretty consistent. I would understand (reluctantly) if 10-15% off as testing can vary but not being off by over 50%?!?! Read the other reviews and you should see the pattern.Search around you will see this as common for similar rechargeable batteries. If you see cheap prices for high mah LIon batteries - too good to be true. Seems those from China are the worst offenders.I suggest investing in a device to test them. Too late for me to return but not too late for you to educate yourself.

Allowed me to bring an old LED flashlight back to service and have spare batteries to swap.

They run out faster than my 2 year old batteries. Not impressed.

This set comes with a battery charger to charge 1 battery at a time and many batteries for you to use. They don't take long to charge but make sure to charge before use because as the battery drains the object your using it with isn't as bright or lively so for best results make sure it's charged so you get the best use out of it
