    an hour - thats good in comparison to mine - i get the grand total of about 15 mins with my brightness as low as it can go and only wireless on!

    it only holds 11% of the initail capacity!

    Usually if you do the battery calibration procedure recommended by Apple you can at least get it to tell you accurately how much time you've got left, so you don't get "sudden" sleeps. Sometimes this can even recover some of the "lost" battery capacity, although I wouldn't get my hopes up.

    For an older laptop an hour really isn't that bad (heck, I borrowed an older Dell laptop from somebody that literally wouldn't last 5 minutes on its battery), but if it's not long enough for you FastMac is one option (their 12" iBook battery is 4400 mah), or you can try the nuPower batteries that OWC (macsales.com) sells--they have a 4100mah one for $100, or a 5000mah one for $130 if you really want to max out the runtime.

    Well as you don't list a location (even just UK would help) I assumed you were in the US ;). Apple sell batteries for £89, but I'm sure there are cheaper options.

    just tested how long it would last,about 50 mins til it went to sleep,last i looked was around 40% then off :(
    £89 is a ripoff imo,ive seen that on the apple site

    Well, Apple does recommend fully discharging and recharging the battery at least once a month to keep it happy.

    Running a couple of full calibration runs might recover a bit of time, or at least give you a more realistic estimate of the remaining capacity (procedure is on the support site--down to dead-empty, not just when it goes to sleep, then charging it up and leaving it to top off for a few hours after it claims full).

    As for where to buy in the UK, you're going to have to hope someone else can make a suggestion there.

    its a bit nutty,the battery has lasted over 2 hours without the charger now:confused:
    got to about 38% then sleeps,i plug the charger back in and it says 0 now. no warning about reserve battery like it used to do randomly when i had 90+% left
