Always pick branded reliable 18650's and don't trust batteries that claim very high capacity at a fraction of the price. Just because the label states a very high number it doesn't necessarily mean it is true. Unfortunately the market is flooded with knockoffs and 18650 batteries with all sorts of false ratings.
