Review: Great deal! - These are pretty decent for small size batteries. They are comparable to an Aspire branded 18350 vape battery rated at 1350 mAh. Vaping at 15-23 watts and they last a decent amount of time for the size. I've put these through about 8-10 charge cycles each and no issues so far.
Review: New Batteries failed to charge - These batteries may not be compatible with all chargers. All I know is I have a functional charging unit for 18350 batteries and these batteries would not charge. Very disappointed. They may have been defective or outdated. These batteries are Made in China. I had to initiate a return.
