Pros: Excellent product, I now own two of these for myself and my partner's netbooks (both AA0-150 models/original battery model UM08A31 - which is not listed in the product description). Whilst I have had my battery for only a week or two my partner has had hers for approximatley a year now and has had no problems with it. Cannot fault the product, easy to use, raises netbook at back slightly which allows for better ventilation, not too bulky, easy to attach. Battery bar reported a wear of 8%, lifetime rating of battery is registered and works for just over 8 hours (wi-fi on, screen brightness medium. One netbook is used for multimedia and simple gaming usage whilst the other is connected to a printer and used for academic purposes.

Cons: No cons found so far.

Other Thoughts: When I ordered the second battery, the first battery to be delivered was defective - it refused to be recognised by the netbook and would not charge. Upon reporting this fault I was asked to complete an RMA. After submission of the RMA I found the after sales department to be very efficient they asked if I could find out a price for the return postage of the product, upon receipt of this information they then asked me to post the fault battery back to them, they then refunded me the postage price and I received a replacement battery within 2 weeks of submitting the original RMA. I am therefore very happy with the product and services received from deal Extreme.

Bottomline: An essential addition to your Acer Aspire One.

Pros: If you use your Acer Aspire One on battery, this battery will give it new life. I have stopped looking for where to plug in my trafo, I can leave my home without the trafo.
It gives around 6.5 hours of working time, can be extended to 7, turning down screen light, turn of wi-fi etc. And I can watch a divX movie without problems.
Now I often bring the PC to a local café, do some work and have a coffee or three.

Cons: A little size, but it gives the PC a nice working angle

Other Thoughts: I was really impressed with how usefull it was

Bottomline: Buy one, or two!

Pros: Very good charge. I received and put in netbook. It is working about 2h30...! When I charge it I think it will work more than 4 hours!!!
Good construction! It seems original product!

Cons: It makes netbook heavier (obvious).
Battery is bigger than original (obvious!).
Netbook dont be plan on the desk because size of battery.

Other Thoughts: Portugues: veio com carga e durou mais de 2h30. Acredito que depois de eu fazer a carga completa devera durar mais de 4h!
Muito bem construida, parece original.
Deixa o note mais pesado. E o notebook nao fica plano na mesa devido ao tamanho da bateria. Mas até q isso nao chega a ser um problema.

Bottomline: I recommend it!!!

Pros: - getting +- 6,5 hours of battery life with wifi on (vista ultimate sp2)
- it tilts the netbook for easier viewing of the screen
- price (compared to original acer batteries)
- installs easily
-

Cons: - makes the acer netbook 'fatter'
- a lot heavier than the original battery (is too be expected)
- recharching takes long ((is too be expected)

Other Thoughts: - uhhm.... 500 characters

Bottomline: A musthave for owners of the acer aspire one netbook who needs a little bit more juice...
