Question about battery memory efffect and electronic cigarettes

[fredflintstone]

I Just got a new 510 battery and I might as well cycle it correctly since it's just a spare and I already have a few others. Here's a link if it might help:

What type of technology is used in e-cig batteries? (Eg. NiMH, nicad, li-ion, etc.?) Should it be discharged all the way then recharged all the way? Or just charge all the way and then drain all the way? Or does this even affect the time frame a battery will last?

Li-Ion. No memory effect.

 

[Grimloki]

The less often its fully discharged, and the less depth of each discharge, the better battery life you'll get.

 

[phishtraveler]

Not sure I understand what you mean? Most e-cig vendors state that they will last for 200-250 charges. So wouldn't you want to make the most of those 200 and completely discharge it before re-charging??

The less often its fully discharged, and the less depth of each discharge, the better battery life you'll get.

 

[NCC]

Most, if not all, of the batteries have circuitry built in to prevent complete discharge since that would decrease the service life of the battery.
I seem to recall somewhere that the circuit cuts it off at around 20% charge ... but, I could be wrong about that figure.

My NPro definitely cuts off before it drains the last of its charge - When you take a drag and it's 'empty,' it still has enough juice to blink its LED at me angrily, demanding to be recharged. I wouldn't worry too much about it, though I have been warned repeatedly to charge it for 3-6 (Some people have even said 24) hours before using it.

The link you provided states the opposite. It states CHARGING it to less than maximum prolongs battery life, which is something your charger would do automatically (depending on if it was built for maximum run-time or maximum service life). It also states the OVER-DISCHARGE is bad (which is true for pretty much everything), but Li-on batteries have built in circuits to prevent this.

In other words, charge it when it needs to be charged, let your charger do its job.

great question Fred,
what may be obvious to some is news to others.

People/newbies wont all know how to go about prolonging battery life. The average joe (moi) doesn't know the scientifics of battery care.

So well done everyone for answering this topic..you've given out knowledge to the masses who can now make informed decisions.

wow....don't i sound like a .... ......lol

All that being said. . .maybe I'm the exception to the rule. All I know is what I've personally experienced. I use my NiCd flashlight, 5 shifts a week, 52 weeks a year. I've been using the same two flashlights for 5 years. Just anniversaried 5 years with the same company. I alternate between the two torches every shift, switching between the two. When I get home I place the used light on the charger that came with the flashlights. Place the used one on, take the charged one off. These NiCd batts are only supposed to be good for a certain number of cycles. A year of my work nights is 365 nights. Means each flashlight has been used approx 182 cycles each year, then times 5 years. That's 910 cycles each light. Being the control freak that I am, I in my wisdom purchased a spare flashlight battery stick. About every three months I throw it in the group to keep it charged and I think healthy. I think I may die before I ever have to use this spare backup battery stick. Knocking on any wood I can find. . .but, I think I'm whipping the hell outta what's normal for NiCd battery sticks. And, whatever I'm doing with them, that's how I treat my LiOn batts. Been at this since May 2010. . .haven't lost a battery yet. Maybe I should buy a lottery ticket. Seems I'm having better luck than most when it comes to batteries. Prior work I lived on the road outta my vehicle, lived off of DC current. Somehow I seem to have established some successful battery charging habits. Either that, or I'm luckier than most. JMHO

Cheers,

Sorry, I provided the wrong link.

This is the link I meant to provide...
How to Prolong Lithium-based Batteries

The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses.

Which is pretty much what he said...

The less often its fully discharged, and the less depth of each discharge, the better battery life you'll get.

So I would kinda disagree with this...

In other words, charge it when it needs to be charged, let your charger do its job.

Because it is better to charge the battery whenever you want, without waiting until it needs to be charged.
