9-Cell 7800mAh Replacement Laptop Battery for MSI U100 (Black)

Pros: This battery definetly have more capacity than stock one :). My U90 works 5-6 hours (playing video) instead ~2 hours as before.

Cons: I don't know what the real capacity. The description here says it's 11.1v/7800mAh. Label on battery (at least, that one what I got) says 10.8v/7800mAh. Linux ACPI says 11.1v/6000mAh. Autonomous work time looks like the last one is correct.
And the other (possible) con - this battery is larger and havier then stock one.

Other: If you need more time on battery - buy it.

Pros: Huge power capacity compared to my stock 3 cell one. This one came shipped with 50% charge which equaled to 3.5 hrs based on my battery meter. It was bang on. I'm running a portable drive, portable dvd burner, blue tooth mouse, usb keyboard & external monitor on this little netbook.

Cons: - The left locking hole does not line up properly with the release pin, so it can slide out without having to slide the release lever. - The size is HUGE, it's like comparing me to Peter North. LOL, the complaints are it's HUGE & LONG... did I say I ordered the BLACK one too? Dirty minds... LOL

Other: Totally happy. I don't have to lug my power supply every where I go now. As for the non-locking battery, I'm removing the battery before transportation anyways because it's too big to fit my netbook case.

Pros: Came very well packed, bubblewrapped and anti-static bag. Capacity is overwhelming, didn't measure continuous use, but in on-off operations, it lasted all day long with 20 and something to spare. And, different from some other reviews in this site, the battery actually locked just like original. No complaints here. PRICE, it's hard to find here and expensive when it's available. 2 weeks to deliver, that sure astonished me. Was counting at least 2x that time.

Cons: It's a bulging "handle" under the Wind. The battery actually weighes more than the netbook. Shifts completely its CG. LONG time to charge to full capacity. I had to leave it plugged all night long to get 100%. It may pose a problem with some people who has the original leather case, it should be a tight fit. As mine was already overstretched (my wife manage to stuff the power brick inside the case), no problems for me.

Other: Great product!
