Larry... I have a third party 10400ma battery for my EeePCs (made in
China - noname brand). And that doesn't happen here. How laptops and
notebooks are generally designed, gives the machine all of the power
it
needs. And whatever is left over, gets passed over to the battery for
charging. So I would try and use the netbook while it is charging and
see if the AC adapter gets hotter or not. It really shouldn't, just
takes longer for the battery to charge.

Wow! 10AH! I'm impressed. If mine had a name, I probably couldn't
pronounce it, either, which would be pointless. Curiously, it reports
in WindowsXP as a Samsung battery...??

Oh, yeah, the full charging current of this quickcharging beast makes
the power brick switcher way warmer than running the netbook. The
switcher would shut it down if it didn't like it, but it hasn't.

It FINALLY DID switch the LED to green, for the first time, last night.
This may have been due to the new battery not being fully conditioned,
yet, and there might be some kind of staged charging going on after the
initial blast that makes the power brick so hot. Every charge gives me
more running. I woke up to a Green LED (charged) for the first time
this morning. I powered the NC10 up on it at...er, ah...9AM (late
sleeper) and it has been running 12 hours now. WinXP's stupid battery
meter still reports we have 2 hours 28 minutes to go before 3% shutdown.
This isn't standby-you-can't-see-the-display running. This has been
AlJazeera TV on the sellphone USB tethered and charging all day. The
beast is powering the sellphone (Motorola ROKR Z6m) modem, too! I'm
totally impressed. I HATE this conservation nonsense sitting in the
dark to save the tiny battery packs. What hooey!



Does the battery get hot while it is charging? That would worry me
more
than anything else. That means the battery is getting too much
current.
My guess is that the battery voltage is much different than the
original. Lower would be my guess.

No, the battery barely gets warm. There's no sign of overcharging at
all. I'm sure the LED is voltage-sensing and finally the newly
conditioning pack came up to full voltage, today. There must be an
initial high charge, then a lower charge until the led goes green then a
topping or maintenance float charge the way it acts.



My huge battery for my EeePC charges fine and the charge light works
right too. Guessing how much time is left is sometimes off a bit, but
it
is okay most of the time. I get about 6 hours with the WiFi on and
high
screen brightness (this is a Celeron CPU). Load tests shows they
overrated the 10400ma. As it is much more like a 8800ma battery. Which
is still ok, as they are only 50 bucks each.

I got $75 in mine with $17 shipping. Some places rate the battery at
7.8AH, others 7.2AH, which is probably closer to the truth on 9 cells.



If your battery doesn't get warm, I guess that is okay. Although you
might think about investing in a larger AC adapter. As that one might
cook itself in a year or two. Look for one 2.5A or more at 19V (or 50
watts or more). As long as the netbook doesn't get hot anyway. If it
does, scratch that idea.


Got that covered:

I'll charge it out in the garage....(c;]
