Indeed... The typical rechargable battery has a life of roughly 300 charge cycles... So they should last about 10 months or so, but usually longer.
If these are what I think they are, then you should be good on batteries for a good long time with 8 of them... You can use the atomizer until it stops working, or tastes terrible. Then just toss it and grab another.
Sounds like you have a few months worth of atomizers, they should last a good week or two, maybe a bit longer depending on usage.
And the batteries should probably be enough to last you until 1) you quit vaping or 2) you decide to try something else
