Battery (power) management?

[skou]

OK, I'm running the Lenovo provided Power Manager program on
one of my 4 running T60s, and it's not quite running OK. (And,
it won't install on the other 3.)

I started to drain the battery tonight at about 9:00 PM. It showed
0%, about 1:07 AM. It's still alive. About 1:30, I kicked the screen
light power up to full, and started watching a youtube video. (Well,
running youtube, to drain the battery)

After about 40 minutes since it showed at zero percent available,
and 15 minutes after I started trying to drain it faster, it's STILL
running. Current draw, (according to the power manager) is about
4 amps. I just got these batteries off of Ebay, and they show a
build date from 12.2013. They aren't that old. They are showing a max
watt-hour of 58.64 (yes, they are ALL the same on that respect) and
a design capacity of 71,28 WH.

MY questions; is there a decent (working) version of power
manager? Is this typical of T60 9 cell batteries?

When I just run the battery conditioning feature of power
manager, it charges, discharges, and charges again, but
just hangs after that. I've got to manually cancel the battery
conditioning program.

It's coming up on almost an hour at a 2 or 4 amp draw,
all at a zero percent capacity.

Oh, $20 a piece, and free shipping. I'm happy about the
batteries, just not the software from Lenovo.

THANKS, guys.

2:01 am. It just died.

That was almost an hour, on a dead battery.

Plugged in the power cord, fired it up, and started
power manager. It's now showing 94.WH as full charge
capacity.

Interesting.

It is not uncommon for batteries, especially third party, to be poorly calibrated.

Usually after running them down and up a few times, as you just did, the gauge becomes more accurate.

It wasn't just running them down and up that did it.

Had to do the running manually, not using the software.

One more thing, why do my other T60s not recognize the
software? Every time I try to install, I get asked, this is an
older version than what you have (I don't have any installed)
installed, do you want to continue? It goes through the install
process, but nothing is there.
