Let’s breathe some life back in to this old thread.
I can understand how people get very excited about more cells and higher Watter/Hour ratings. But here is some uncommon knowledge to help you make an _informed_ decision.
‘Cell’ refers to a Lithium-Ion cell, specifically the ’18650′ 3.6/3.7V cell. 3 Cell batteries come in at 10.8 or 11.1V etc.
Now here’s the juicy part: Not all 18650 cells are manufactured the same! Most Laptop manufacturers use Japanese made cells. The Japanese made 18650 cells are made by Sony, Sanyo, Panasonic, Toshiba. Some Brand-name Laptop manufacturers use Korean made cells – LG and Samsung. These are generally quite good, but a tad behind the Japanese ones. NOW…we come to the no-name aftermarket ‘compatible’ or ‘generic’ batteries. Most of these use Cells made in China, by Ultrafire or Trustfire, or any one of 100 other low quality battery.
With Japanese Cells, they are rated to supply 80-90% of their rated power after 300-400 cycles. (you’ll usually see 500 charge cycles in specs…sure. but the battery will only charge to a fraction of its ‘new’ capacity)
With Korean Cells, the data is not so readily available. They do tend to drop in fully charged capacity after fewer charge cycles than the Japanese ones, but in general the price difference reflects this.
With Chinese Cells, the manufacturing QC is basically non-existent. Often individual cells are dead or have short-circuits inside. In general you will be lucky to get 100 charge cycles, and at that point their fully charged capacity will be minimal.
Also note, Lithium-Ion batteries degrade in fully charged capacity from the moment they are manufactured, regardless of Charge cycles or how long they are left sitting with low charge. Chinese cells seem to in general degrade to half their nominal capacity within 1-6 months. Japanese cells will degrade too, but the half-life is 18-24 months.
To sum up: Don’t buy a no-name generic 6 or 9 cell battery because the specs look oh so pretty, unless you can find one which uses Japanese cells and offers a substantial warranty.
After a bit of a search on ebay , some dude bt-flash is selling Acer batteries with 3 year warranty and Japanese cells. Slightly more expensive, buy you’re getting proportionally much more than what you pay for.
Adios.

lithium batteries are very expensive but they are very lightweight`-’

I have the AcerOne 532h. Ads state battery life is “up to 8 hours”. I totally drained and charged battery 4x so far, and have never reached more than 5.5 hours. Battery = 6 cell, 10.8V 4400mAH, 48wh.
Use is occasional web surfing but primarily Open Office applications

Battery shuts off (hybernate mode) when it states about 20 min. left, but I think that’s a Windows7 issue not the battery.

What IS the typical life? Is 5.5 hours normal? Or should I trade-in for a new battery (still under warranty)?

6 cell 4400 mAh battery or 3 cell battery, I like to choose the 6 cells, because it’s longer last than 3 cells. And the weight is not too weight.
