Where did you buy them, and do you know for a fact they are genuine? You really want authentic sellers for batteries.
Efests are known offenders as far as inflated battery specs and etc. I'm not really fond of them. You may find you get poor life depending on what wattage you want to use, they just generally their ratings are pretty worthless. If the Sony's are authentic there should be letters on them explaining their specs and ratings (printed right on the wrap) but again unless you used a reputable seller (I don't consider most vape shops "reputable" sadly) it's going to be hard to know exactly what you've got. They could be seconds, purchased from a vape shop and then rewrapped and rebranded by the vape shop (knowingly sometimes, sometimes unknowingly.
I'd suggest checking out these blogs, they offer a great deal concerning battery safety generally and in Mooch's blog, you may find a "real world" test for your batteries and the "real world" rating. There is also a table that you can look at, it sort of lists many of the batteries in use with their true ratings and recommendations, and in the last cell, Mooch lists "reputable" vendors, and the good news on that, is they are usually far less expensive than purchasing through a vape store, these sellers do volume, and batteries arrive fast .I use IMRbatteries.com and they always send extra cases and wraps. You'll also get a "don't use in vaping" warning, but most of the "true" authentic battery sellers know batteries are being used in vaping, and wish for nothing to do with it, since at times batteries are used unsafely by new users.
