Anyone know of a good (preferably free) software for reconditioning lithium ion batteries? Specifically for Lenovo T60 laptops, though I doubt the model would make much difference?
Thanks!

Never heard of what your asking about.Cool idea though.Quote:

I've heard of it, but not for some while... few years ago some laptops were supplied with it in the laptop management utilities... but that was before the li-on and was about removing the memory effect.
What is the problem with the batteries Percy?
NiCad and to a lesser extent NiMH batteries did benefit from "exercising" to counter memory effect, as NooNoo says. Li-Ion doesn't benefit from deep cycling, but does age in a consistent way, and power management will benefit from periodic re-calibration.
Percy, is there an option anywhere in the BIOS setup to initiate a battery re-calibration cycle for the power management? If not, try just running the battery right down until power management shuts the laptop off, then after a full recharge see if the results are any better. If not (or if you've already done this) and the battery is a few years old, it may simply be nearing the end of its useful life.
There's some useful information here:

Thanks for the replies, folks. The specific situation is that I've got a number of these T60s that're in warranty, but the batteries only have a 1 year warranty, so those're no longer covered and the batteries have died. They'll show as fully powered, but you pull AC and the machine powers down.
Years ago, NiCad batteries had 3rd party reconditioning software that let you wipe the "memory" of the battery to get rid of partial charges, etc. I'd hoped that the new batteries had that too, but checking around it doesn't appear to be the case.
Seems a shame that the newer "better" batteries die this quickly, but I guess that's just the industry.
Thanks again for looking into this though. :)
I have found that this behaviour can be indicative of a bad mains adapter. Leaving the batteries alone on a shelf for a couple of weeks and then inserting them into an already powered up laptop (with a new adapter) can often kick them back into life.
But yeah, they go with annoying regularity about 24 hours after the warranty expires.
Look on the bright side, Percy. They aren't bursting into flames at least.
We actually had three of the Explodo-matic batteries here. None of them caught fire or anything fun, but they were on the bad P/N list. IBM's pretty good about getting new ones out to you.
There is a software for Lenovo Laptops. It is called Battery Maximiser. It works great and will give you the discharge count for the battery. If you go to their website you can choose to download drivers for your model and then select the software. Hope that helps

If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, ...
