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!!!😄

The battery charger works well. It's a slo...w 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+ ba...tteries. 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 gre...at 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.
