Chat away in the forum in case it's of any use to someone else I spose
To cut a long story short, I went here:
http://www.kingbattery.co.uk/advanced_s ... =1&x=0&y=0The batteries for the different Acer Aspire models all seem to be much of a muchness, but do check and see if either your netbook model number or the battery model number shows up there.
I went for the 9-cell job, simply because I rarely take the netbook away from home anyway, but I utterly
detest wires
£37.92 delivered from those nice folks in China (so a slightly longer wait involved), though the site has a UK address... it's up to you really

, the way I was looking at it, either Paypal or my credit card company should cover me if it was dodgy.
The battery itself adds a fair bit of weight, as you'd imagine being 9-cell (smaller capacities are available), but it's not going to break your back or your wrist carrying it! Personally I like this if I'm using the netbook on my lap as it keeps the whole thing steadier.
Also, with the
slight size issue and to keep with the shape of the overall Aspire design, the battery elevates the netbook slightly. This is just the undercurve of the battery and the attached rubber feet, and raises the netbook by just under an inch at the back and obviously elevates the keyboard, but not in a 'Are you kidding me?' way, so don't worry
I'm just telling you
everything I can here, the extended battery is no trouble at all, if it sounds terrible it really isn't!
I get over 10hrs with it using Wi-Fi with the screen brightened beyond the usual power-saving bit, and it doesn't heat up much or anything like that.
