Li-ion Battery Regeneration??

well... you try telling a H/PC not to discharge quickly when you're watching a video in TCPMP

But isn't it impossbile to overcharge a lion using the charging circuit that comes with the pack? And how can a conditioner bypass the circuit in the pack? Too many questions, not enough answers

Well, aren't most of us here on 5-7 year old lions? Some of us on even older cells?
That debunks any 3-5 year lifetime crap.

If lions degrade 10%/year then one of my original 6651 packs must be a monster pack. It still gves 4+ hours with wifi, and since it's 5 years old it would be 1/2 original capacity of 1800mah=900mah?

So much for the 10%/year thoery, which itself contradicts the 3-5 year lifetime thing.

I'm off the read the CESD here.

BTW, those abused nicads were discharged to 0, reverse charged (by mistake), drained and properly charged and they didn't explode or die. One leaked tho'.

The nimhs that came with my Fuji camera won't hold a charge, they've always been topped up and never deep cycled, so bad QC or bad brand, I don't know. They only worked properly for about a year.

1 and 3/4 plays of 'Anna and the King' (my benchmark DVD) - which is 2:13:13 long; with the display on dim and using headphones. Jornada 720. 2004 battery.

Course it's not impossible. You put your faith in a PCB not to fail.
As Pete says, you can do the reverse too, and by allowing the cells to drain out completly for much in the way of time you can trip the end of life pixie switch that will prevent it from charging back up again.

I have some 15 year old NiCad AA's, which through successive house moves got lost somewhere.
I found them a couple of weeks ago, they can't have been used for at least 9 - 10 years. Test charged a batch up, and low and behold, they work better than my 2002 1400ma NiMh's.

Cmonex, some nicads never die. I wish I knew why. Supreme QC at build I guess.
I have a pair of Radio Shack 9v nicads, over 25years of age that both work great. I use them once every couple of years in my metal detector when I get the urge to treasure hunt.

I do know about memory and those nicads I have were discharged to 0.1v once a month or so. I've done the same with my Fuji nimhs to no avail (after they started short life). My RS nimhs short or deep cycle fine.

FWIW, the J565 here (lithium polymer) has been deep cycled and recharged every day or other day for the past 4 years and still maintains 90% or better runtime. It won't die.
