So I've just started using my Sigelei 150w and it came with two Efest 18650 35A's. I have two VTC4's on the way and they should be here in a day or two, but for now I'm stuck with only one set of batteries. I know with cell phones the belief was you would want to drain your phone till it dies then charge to full as soon as you got it. With the phones today I've heard you don't have to do this anymore. But I've never used rechargeable batteries before so I'm not sure the best way to take of them. So I just have a couple of questions regarding the best way to take care of them to ensure safety and longevity.
1. How low should I let the battery get when I'm using it? Let it die (0%) or at what percentage should I plop them in the charger?
2. About how long is the life of a battery? I don't mean from charged to empty I mean how many recharges can the battery get and still be safe to use?
3. If I'm in a pinch and have no other battery or charged mod with me is it ok to take the batteries out, charge them for a little while (not to 100%) and use them until I'm able to swap them out for fully charged? Or should I just suffer for awhile until I can get my hands on fully charged batteries?
4. I have the Nitecore D2, is it safe to let the batteries remain on the charger if they've reached 100%? For instance while I'm sleeping? Or should I wait to charge them when I'll be awake when they reach 100%?
5. And lastly, If I have one pair of batteries (Battery1) fully charged and in my mod and one pair of batteries fully charged (Battery2) sitting on the side (not in the charger) will the batteries on the side (Battery2) lose their charge in the 2-3 days it takes me to drain the first pair (Battery1)?
