A big test of cheap Ebay Li-Ion 18650 batteries. This time I tested 7 more types and found that 2 of them are real. The 1800mAh and 2000mAh cells really have the declared capacity. They cost $ 3.76 per 2 pcs, this is only 1.88 per cell. On the other hand, the fake cells rated 2 500 - 12 000 mAh actually are only 400 - 550 mAh. And they are more expensive than the real ones!
