Battery life - full cycles prolong life?

[Kind Head]

Do e-cig batteries work anything like cell phone batteries and similar electronics? In the way that with cell phone batteries, they say going through a full cycle helps prolong the life of the battery, and keep it holding a charge better. I was always told that I should not keep my cell phone plugged in a charger all day. I should let the battery get close to dead before charging it. Then letting it get a full charge, and repeat cycle. I was told that only letting it get 50% low, then recharging, or just keeping it on the charger all the time, causes more "wear and tear" on the battery.

I'm not 100% if that's even really true with cell phone batteries. Even so, does this theory apply to my e-cig batteries? Should I let them run out before charging them back up? Someone told me that this wasn't the case with newer cell phones. They said the older phones used different chemical batteries, and this wasn't really necessary any more.

Anyone care to learn me something about batteries?

I believe they are referring to the memory effect. Older chemistry batteries had this issue.

I have four sets of 14500s that I rotate. I don't always wait for them to discharge before placing them in the charger. This isn't intentional. I always put freshly charged batteries in my PV and take a backup pair with me when I go out. So, the ones that were in the PV get recharged.

It's been 5 months and they still last as long as the first day I got them.

theoretically it shouldn't matter with the batts we use...in reality, it is better to change out batts before they reach that point...for myself, as soon as I notice the hit falling off, I change them out...

Most rechargeable e-cig batteries are Li-ion batteries (lithium ion). Li-ion is also commonly used for cell phone and laptop batteries. Protected Li-ion battery cells include circuitry that prevents overcharging and over-discharging, so it is not easy to run these batteries down completely.

Li-ion batteries have no charge memory. The do not lose charge capacity due to charging before they are run completely down.

Older style NiCd (nicad) rechargeable batteries benefited from being run dead prior to recharging. This is not the case with Li-ion batteries.
