Charging Batteries

[DreamVapor]

I killed one of my batteries recently after only a month or so. My boyfriend thinks that it's because I wasn't letting it go all the way dead before recharging it. My problem was the hit just keeps getting weaker and weaker with the battery. So, from now on I'm going to puff on 1 bat until it gets weak and start on another for a strong hit, but continue to puff on the weak one between strong hits so that the battery runs all the way down.
The b/f says that the battery has like a memory of the charge and if I only let it get half way uncharged the memory will make it die sooner...something like that. Just wanted to share this. Don't remember reading about letting the battery completely die before recharging in here yet(course maybe it's common knowledge and I should have just known it, lol).

For all you ever wanted to know about li/ion batteries Charging lithium-ion batteries

I understood about a 10th of that, maybe less...
Thanks for trying though lol.

Basically li/ion likes to be charged and doesn't need full discharge (no memory cycle) like the ni/cad ones did for so many years. People just got so use to doing that with the old ones that they still think it applies to all rechargeable batteries.

Unlike nickel and lead-based batteries, a new lithium-ion pack does not need cycling through charging and discharging. Priming will make little difference because the maximum capacity of lithium-ion is available right from the beginning. Neither does a full discharge improve the capacity of a faded pack. However, a full discharge/charge will reset the digital circuit of a 'smart' battery to improve the state-of-charge estimation.

What this means is to discharge every once in a while to reset the protector circuit because e-cig use the "smart" battery. This does not have anything to do with the life of the battery but is about helping the protector circuit read the voltage range properly for safe use.

From the Do's and Don'ts section at Battery University:

For Li/Ion:
Do charge the battery often.
The battery lasts longer with partial rather than full discharges.
