Is that possible? 9cell battery for a T40

[orck]

Hi there
Yesterday I received a used battery I bought on ebay for my T40
it is a 9 cell battery for T4x with the PN 92P1073 (which I know it's being recalled)
below you will see the report from Battery maximizer which says that this battery has been charged for over 100 times from February 2007 but it still can hold its maximum design capacity of 77,76Wh
Is this possible?
Also from your experience the report of total of 6 hours working is it true? (broswing on the internet, email stuff like that)

Looks like it is in great shape, 6hrs is a little optimistic I think, closer to 4 depending on your screen brightness.
Best way to find out is run it on the battery down to 5% or so and see how long it goes. Specs look good and according to Levono's site, your battery's bar code shows it is not included in the recall.

Yesterday when I receive the battery I downloaded the lenovobatteryprogram.exe from lenovo and after I run the program it said to me that my battery is being recalled
I also place an order for a new one, if you check again with this serial number 11S92P1072Z1Z9YM625250 it says "An order is already in process for this battery. 2008-04-04"
right now it seems that this number may be not optimistic (with light use of course)
thanks for your reply

Sounds great, any time you can get a new battery free, I would not argue. The Levono recall page I went to only required your battery bar code number - the 1Z9....... number, maybe the have 2 different databases to take that big long serial number you entered

I guess you have to return the old one right?

See my sig. It was taken with a new 9-cell and an UltraBay Slim (which when new add about 50 minutes run time). Power Manager was set to a low consumption profile (CPU on Low or Lowest).

Did I get that? I don't recall. About 5 hours certainly. Of course they age as they're used (one UB Slim battery is worth about 10 minutes, but sometimes the system turns off with it in), so your recall baby might've been run down very little. E.g. used for short spurts, then topped off.

I certainly urge you to experiment with Power Manager profiles. I have 3-4 of my own, some which moderate high performance (Adaptive chosen for CPU speed) regardless of power source, and a version of the default "power source optimized" which doesn't slow down the system quite so much, but agressively conserves HDD and video consumption. I tend to get 2+ hours on a 2 1/2 year old 6-cell battery.

I do recommend UltraBay Slim batteries as handy way to swap out main batteries without finding the adapter, and as a 30 minute reprieve when I'm really out of main power juice.
