Click Here to Order Extended Battery for ACER Aspire One Blue ZG5 UM08A73 6600mAh from Amazon

The battery life of your 9 cell ACER Aspire One UMPC is limited like any other device containing rechargeable batteries. The battery capacity of the ACER Aspire One UMPC drops every time you use it. This replacement battery will extend the life of your ACER Aspire One UMPC. When the available battery time is shortened considerably a probable cause is that the battery of the ACER Aspire One UMPC has reached the end of its life. The battery life of the ACER Aspire One will vary according to how it is stored charged and through general operating conditions.

This battery has three times the capacity of the standard battery, and not unsurprisingly requires three times the space. Basically, I now have a battery with a netbook attached to it. Just imagine that a second battery pack is added behind the standard pack, and a third battery pack underneath. If that is what you want, get it!

As the photos suggest, it’s a big beast. If the aesthetics of the Aspire particulary appeal to you, then you might be put off by having a big lumpy battery pack hanging off the back. On the other hand, if you regard your Aspire as a proper mobile work horse then you may find yourself really growing to love the way the battery pack acts both as an angled keyboard rest and a handgrip – holding the Aspire in one hand whilst you type/mouse away with the other hand is now quite comfortable and secure.

Since getting this battery, my Aspire has been turned from being a cute little toy into something more serious. It can be taken out for the day and be actually used without wondering about the battery going flat It would be nice if it could be a bit lighter and if the outer casing was a better match for the Aspire. The larger battery successfully extends the runtime of your Aspire.
