Actually laptop batteries are usually the pick of the pack. They are going to be genuine and are going to be top quality. Often the batteries we buy are "factory seconds", they didn't test as well as they should from the factory (this is talking companies like ****fire, fakes, and the like. AW and genuine OEM batteries are good). What you should be more worried about is the state of them. They are used batteries, which is a gamble. How old are they? How sure are you that they haven't been overcharged or discharged? Do you have a way of fully testing them?
go to any flashlight forum and search "laptop pull". You'll get the idea
edit: sitting in storage for two years? I'd pass on this batch. They likely have been undercharged for a long time
while you do have a point, this is not CPF.
not all packs are created equal,
2300mAh 18650... i highly doubt its high drain...
And not all ECF users are competent enough to disassemble a battery pack.
And of all places the Newbie forum is not the place for this kind of information.
Just the other day, a user wanted to take off the shrink wrap on a battery, just because it looked cooler on his DIY mod... see my concern.
i know a good bit of battery info, and do have machines to test batteries, but even I wouldn't take the risk on a used laptop pack.
I've owned 10 AW's in the 3 years that i've been vaping... They have paid for themselves. no need to pinch pennies in that department.
I'me just advocating safety here, Vapers shouldn't be missing teeth, due to an oversight.
