Hi all, This discussion is very interesting. My question is this: Do the lithium batteries have memory? What I have heard is some rechargeables have memory and that if you say for instance, have all you ecig batts dead, can you do like a half hour charge just to get your vape fix? Will this be a problem?  Not as such memory effect was only really a problem on Ni-Cad's what would happen is the battery would run for so long then suddenly drop off. It was caused by part charging. The best way to avoid it happening was to run them flat before recharging. Lithium battries do degrade with use but this mainly happens in high C draw applications, eg. running ESC's for high speed motors etc. Hope this helps. |

I have a KR808d-1 style e-nic I use for backup. I have 3 of those batteries and 2 PCC's for them. Nice small battery but it doesn't take much time to deplete the battery. I use if for short trips out of the house or when I am doing a lot of physical activity in case it falls out of my pocket like when I'm roughousing with my young sons so I don't lose my favorite tornado tank. I can get a tornado tank battery to last me from waking till I go to sleep. The one reason I keep them around is these particular batteries have a full LIFETIME garantee. If a battery dies I just call the company, get an RMA number and then post it back to them and a free replacement is on it's way. I've had battery issues with then before and they sent me replacements and a SASE bubble mailer for my dead battery before I even shipped out the dead battery. It's a decent company BUT they ONLY sell the KR808D-1 style e-nic, no bottled juice , thread adapters, etc. I don't buy their products anymore but keep them around and refill the cartomizers with TW e-liquid. My only source for my e-cig hardware and supplies is TW for the past few months and I don't see any other suppliers with the discounts and specials , like the yo-yo promo and the weekly discounted items. Add to that the new lower price structure for atomizers, batteries, etc and I don't have any reason to go elsewhere for my supplies.

Simple Guidelines to Prolong Lithium-ion BatteriesDo not discharge Li-ion too low; charge more often. A random or partial charge is fine. Li-ion does not need a full charge. Limit the time the battery resides at 4.20/cell (full charge), especially if warm. Moderate the charge current to between 0.5C and 0.8C for cobalt-based lithium-ion. Avoid ultra-fast charging and discharging. If the charger allows, lower the charge voltage limit to prolong battery life. Keep the battery cool. Move it away from heat-generating environments. Avoid hot cars and windowsills. High heat and full state-of-charge, not cycling, cause short battery life laptops. (I assume this include other devices) Source: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

I was reading this thread last night and, oddly enough, there was some interesting lithium battery news today! Apparently, the University of Leeds is developing a gel lithium batt! http://www.bbc.co.uk/news/science-environment-14852073 |

Crossbow,
i'M IMPRESSED. I am a Technician by trade and your knowlege of those batteries is really good. Excellent graphs. I learned a couple of things here.

Great info on this thread.. I suppose by now everyones heard about the guy with the exploding e-cig battery in Florida or Alabama or something? What would cause something like that? I apologize if theres another thread about it but I didn't see one.
