  • Not 9900Mah False Advertising
Size: 10 Pack Color: Flat Top
These batteries are far less than 3000Mah. Do not buy! I don't get why Amazon stopped selling all of the good, reliable 18650 3.7V batteries. Now they only sell a handful of them that don't have any reviews or I've never heard of. Very disappointing.
