Lithum ion batteries do not need to be charged like that. But Nicads do, they need to be discharged 100% then recharged to slow down the memory process that these batteries develope over time.


So how do we do this? New battery>drain>charge or New Battery>charge>drain>recharge..... ???

Lion batts-need to be cycled 4-5 times to maintain chared capacity(charge>drain>charge/drain/etc)

NIMH batts-need to be cycled as well, i cycle all of my batts about 5-6 times, these do not suffer from memory effect, so they dont need to be drained before charging, once the batts have been cycled a few times you can charge them anytime

NICD batts-suffer from memory effect and have to be drained 100% before charging, still wise to cycle these as well a few times

SLA-should never fully discharge, i keep my SLA connected to the wall-wart at ALL times, theyve literally been 'charging/trickling' for YEARS steadily

Lion batteries do not need to be cycled
this is a myth please read below and follow the URL for a more detailed exxplanation.

Summary of excerpts on using LiIons from Batteries in a Portable World:  http://www.buchmann.ca/

There is no memory and no scheduled cycling is required to prolong the battery's life.
The typical life span of a Li-ion battery is two to three years, whether it is used or not.
The internal resistance of the Li-ion batteries cannot be improved with cycling. The cell oxidation, which causes high resistance, is non-reversible. The electrolyte slowly eats up the positive plate and the electrolyte decays. This chemical change causes the internal resistance to increase. In time, the cell resistance raises to a point where the battery can no longer deliver the energy.
The recommended storage temperature of a lithium-based battery is 15°C (59°F) or less. A charge level of 40 percent allows for some self-discharge that naturally occurs; and 15°C is a practical and economical storage temperature that can be achieved without expensive climate control systems.

thanks for the info, i have read MANY articles on lion batteries, and i have come to the conclusion that they do initially need to be cycled, i am just an anal person and feel better if i cycle them ;D

i do believe that they can go bad if they sit on the shelf w/ out first being charged, thats why i got a somewhat dud on the one i got off of ebay

and i know lion batts are the shit because of size/weight/capacity but why do they freakin die so soon in their life? 2-3 years is horrible, especially when 722 batteries are 40 dollars a piece for the 6600mah sony ones, cant they integrate an SLA/NIMH  type battery that has the size/weight/capacity of a lion w/ the lifespan of a NIMH/SLA ???

i have had my 6v ecocharge SLA's for years, i had two die on me last year, but they were freakin 7+ years old :) one is still going strong after about 5 years being constantly trickled :)

You are the posting master I just looked at your stats wow. I am not going to argue the point with you this what I have read on the subject there was also a study done on the subject.  ;D

thats cool, i am not saying youre wrong at all, just saying im anal and cycle all of my batts w/ the exception of SLA's

Lithium was what I was questioning. My 2 7.2V 5400's seem to be losing their zip. They are about 2 years old and I did recycle them 3 times when new. However I never stored them in a fridge. I fully believe that the recycle did nada. It was the improper storage that shortened their life. I still use them with the V3, but always carry the second battery and usually switch after 3 hours. At that point I'm done to one light and feeling uncomfortable. New, they were good for at least 5+ hours. I think ???

Now I've got a pair of new ones, 9V 6000 mah, and was just trying to remember the proceedure, if any. Thanks for the article Chris, but there are still a good number of folks who believe in cycling. ;)
