Replacing 3 cell battery with 6 cell battery

I have an 8.9 inch Acer Aspire One with a 3 cell battery. The battery life has steadily been decreasing and I would like to replace the battery. Can I buy a 6 cell or 9 cell battery or do I have to replace it with another 3 cell battery.

Thanks!

 

There are 6- and 9-cell batteries available for the 8.9-inch Acer Aspire One. Just search on "aspire one battery."

I added a 9-cell to mine for use in long airline flights. It gives me 6-9 hours of service, sometimes more, especially since I have to turn off the WiFi card during flight, which saves a lot of battery drain.

With the 9-cell, you can't open the screen as far (but more than far enough), but the larger battery pack acts as a "riser" on the rear, raising it to what I think improves the typing angle AND air flow for cooling. A picture is here, although the price shown is a lot more than I paid: http://eeepc.net/9-cell-battery-for-acer-aspire-one/

Agreed... im currently selling my 3 Call on eBay at the moment and planning to use the money from the sale to put towards a 6 or 9 cell from china/hong kong.

Ive read some are duds ( 6 and 9 cells from outside of the EU) so keep in mind the sellers feedback before purchasing.
