These batteries were a great deal and came in the mail a lot quicker then anticipated. The only downside is that i use them in my kanger tech five 6 vape and so i needed 5 of them and they dont hold enough charge to really get me through more then a Day on my vape. But my biggest concern when i bought them was to make sure i had batteries in order to use my vape. So to be honest i paid like 4.00 bucks give or take for 4 batteries and a charger which is a steal. And they do get me through a whole day on my vaporizer which has me happy. And i am not sure if its the batteries fault or the fact that my atomizer is just really powerful. It may be normal for the batteries to only last a day. But for the price and the speed of which they got my order out in the mail and to me i will definitely be ordering more in the future. Which then i will have more then one aet to switch out each day while the next set is charging!!!😄Read full review

The battery charger works well. It's a slow charger so if you don't mind waiting for 4 - 6 hours, it's good enough. The batteries that are labeled 6000mAh are another story. I fully charged the batteries using the charger then ran a capacity test on one of them. Using a constant current load of 1/10C (500mA) for a theoretical 6000mAh cell, the total battery capacity came out to roughly 1200mAh with a test termination voltage of 3.0 volts. The test results were nowhere near the 6000mAh capacity stated on the battery label. So my conclusion is don't trust what yo see just because it's printed on a label.

Used these to rebuild Ryobi 18v power tool one+ batteries. Used on both the single(5 cells) and double(10 cells) packs. Not perfect but a great value, packs won't charge to green on the led tester, but I am happy with the charge that they hold, hard to say what mAh these hold as some chargers charge to 1100+ mAh while my IMAX b6 will only charge to 900+ mAh. Had one vent on me during solder, but that was my fault(shorted + to -). My advice is solder outside just in case.

A powerful battery. Works great when fully charged, but you'd better keep a fully charged set at the ready. My light will drain them fairly fast.

These batteries are advertised as 3000mAh batteries. They are not. I received 10 batteries and they were just dumped into an envelope. There was no protection to prevent them from shorting out against each other. I measured the voltage when they arrived and they were all sitting about 3.8 to 3.85 volts. I put the first 4 on my Nitecore Intellicharger i4. After a few hours the first batch came off and read 4.14 volts. I put the second batch of four on. A few hours later when the second batch was done charging, the first batch were already down to 4.04 volts. I popped one of the "batch 2" batteries on my discharger (SkyMax B6ACv2) and it revealed the first battery only had a capacity of 1100mAh, the next only had 881mAh, and the last one I tested came in at 1081mAh. All of these are drastically below the advertised capacity of 3000mAh. These batteries would not last long in any device and I don't recommend anyone buy them.Read full review

DThis purchase was forced on me after I discovered that the "great buy" of a nifty miniature flashlight I had purchased didn’t use any of the standard type of batteries available in the states! Instead I had to contact the supplier of the flashlight and found that only one type of battery would work and it was rechargeable. That meant I had to buy a recharger as well.... in my hurry to get the best of a "not so good deal after all" I ordered this unit and then discovered there were other units that would recharge multiple batteries at one time ! Moral of the story: DON'T RUSH INTO A GREAT DEAL - until you’ve checked out all the options !!!

They seem to be working pretty well, but I will say that the batteries seem to be a tiny tiny little bit bigger than the other ones so I have to work a little harder to squeeze it into my devices

These batteries came pre-charged and ready to go. Don't know how long they'll last but they seem well made and durable. Would recommend to buy. For the price you can't beat it. Also comes with a charger. But don't leave the charger running and leave the house because I don't trust these cheap chargers. Other than that the batteries are a good deal.

I use a 5000mAh normally in my flashlight and the battery lasts a long time before I charge. In fact I usually charge without any drain in brightness. My first time using these which are 6000mAh, After a couple of nights of usage the batteries died quickly and without warning. So I am not sure yet but may not live up to the 60000mAh label.

Very cost effective product, these do a really fine job in low to medium current drain applications. I use them in UltraFire flash lights on high for up to two hours before they dim slightly then swap in another battery from a plastic case in my pocket. If you don't need the high setting they will go for about four hours on a medium setting. Never take them to zero charge or they will ruin. Recharge them when you notice the light has dimed slightly and they will last a long time.
