Hi guys, I have an Acer Aspire 6930-6942 (http://www.newegg.com/Product/Product.aspx?Item=N82E16834115539), and it comes with a standard 6-cell, 4400mAh, 11.1v battery (P/N: AS07B41). Due to the form factor of Acer batteries, they're unable to hang out of the back to cram more cells in like Dell and other manufacturers' batteries. I get pretty poor battery life on this laptop, and I was hoping to either find a higher cell count or higher mAh battery. Apparently there are some compatible 8-cell batteries, and some batteries with higher mAh... However, I see most of these listed at 14.4v, which I assume is not compatible (even though it says they are?).

Before I go off ordering a battery, can anyone help me out here? I'd like to find the highest capacity battery I can, but I don't really know what to look for.

Thanks in advance to anyone who can help me out!

I don't like bumping, but does anyone have any suggestions for me?

Yep.

Good luck finding batteries.

Not happy with battery life? GeF-M9600 and C2D, what are you talking
about? You expected battery life from a gamer notebook? Even worse,
a cheap gamer notebook? Reality check. Dedicated graphics are power
hogs. The only thing you can do to prolong battery life is to clock down
the CPU and GPU and undervolt them in idle, and turn screen brightness
down. Still, you won't get much battery life out of them. If you want
battery life, stick with integrated graphics, a smaller screen and a low-
voltage cpu.

If I were you, I wouldn't bother with new batteries (they are expensive
anyway and won't yield much better battery time with that hardware);
low-end Acers are prone to dying prematurely anyway...

Really now, there's nothing to get worked up about. I'm perfectly aware of the consequences of dedicated graphics on my "gamer" laptop... I thought I asked a fairly simple question about batteries

I am not worked up at all -- it's just that you won't get any significant gain
out of a battery change. It's a gamer notebook after all, it's not for battery
life, but for mobile gaming. The most you can do for it is downclocking and
undervolting in idle -- may even have better results than changing the
battery; also, it's free (well, it costs time), while a battery is anywhere
from ~$60-80 (generic battery from ebay -- usually lower capacity and
may even be used) to $200-300 (manufacturer replacement batteries).

Well, I think what I may just end up doing is getting another battery... That way I have effectively double the battery life.

I was just hoping that I could get a better battery than the stock one, but I guess it's not possible with this laptop. Oh well.
