The first thing to acknowledge when choosing a 18650 battery for your device is the battery brand. Not all brands are designed equal and often you will see are not very honest in their battery ratings. This is particularly true when considering the Chinese re-wrapping brands.

Any manufacturer or brand aims to sell as many batteries as possible, but some companies have been known to expand their ratings to seem to offer a better product than the other.

This method of expanding battery specs is unlawful and can be very risky to consumers if gone unchecked. Thankfully, there is a watchdog in the lithium-ion battery production known as the battery mooch who gives thorough testing and will call out these brands for their unlawful usage.
