Extra Battery - 12" PowerBook
Battery Supplied with PowerBook in November 2003
Written by RD from HARROW
10-Feb-2006
I purchased a 12" PowerBook at the end of 2003, and the battery has served me well for a long time... in fact, I could get 5 hours from it for a very long time... but in the last 8 months, it has deteriorated, and I get a GRAND TOTAL of... (wait for this)... 8 minutes!
Anyway, I am just about to purchase another and see how I get on with that, after which I will buy a second, or look for an alternative. …More162 of 238 people found this useful

Battery use.
Written by KH from BATH

We have two powerbooks, one is well over 3 years old, the other 2 years . The older powerbook still has its original battery, the newer powerbook has had two (so far). The reason for the difference? Me! Yes, me! ...Keeping the machine plugged in when the battery is fully charged... I now avoid doing this. I allow the battery to drain and then recharge as much as possible and when the charge is showing 100% I remember to unplug it.... …More

Remove Battery when running on Mains
Written by HM from PRESTON
23-Nov-2007
I have had my Powerbook for 2 and a half years, after the first 18 months or so the battery power reduced dramatically over time to 5 minutes. When purchasing a new one I was told that when sat at home and using the mac running on the mains that to save wasting and draining battery power to remove the battery when not charging it. This stops the battery being overcharged and discharging, pershaps worth a try? …More

Correct use + OS Tiger possibly not too bad
Written by DP from London
19-Apr-2009
I bought one possibly 2 years back and 3 months ago it was performing just as negative as most reviews say.
However when I couldn't cope with Leopard on my Powerbook G4-12' anymore (too slow) I reinstalled the system back to Tiger and guess what, the battery's performance has increased dramatically. In fact from less than 30min performance under Leopard it pushed back to 1h30min performance under Tiger OS. (Though the use of computer is limited to Word and Internet browsing. DVD playing will give about an 1h.)
In the end do not charge your battery continuously from AC (like I did) but use the actual battery whenever possible. Plus probably Tiger is the maximum OS that should be operated on Powerbook G4-12' even with max RAM, then perhaps this battery is not too bad as most reviews say it is. …More11 of 12 people found this useful

Extra Battery - 12" PowerBook
Configure your laptop for maximal battery life
Written by LL from Norwich
13-Mar-2009
I've had this battery for 3 years now and have been very satisfied with it. 532 charge cycles so far (i.e. 133% of its original capacity) despite having the charger on all day. I can still get up to one hour battery life depending on what I'm doing. From my experience, it's all a matter of configuration. Don't leave your battery to drain completely, configure your energy settings for longest battery life (put the screen and hard disk to sleep as soon as possible, reduce processor speed, turn off bluetooth and wifi if not using them…) and remove your battery when your laptop is running on the mains. I also avoid to do anything that is too energy consuming while running on the battery and make sure my computer goes to sleep if idle after one minute. That's how I was able to get up to 4-5 hours autonomy for a long time.
Apple also gives £10 off for this battery to students and teachers through the education store and if you compare the price with Dell, these batteries are not particularly expensive (many of Dell's batteries are priced £90 and over). So it may not be THE best battery in the world, but it's still pretty good. …More7 of 10 people found this useful

Extra Battery - 12" PowerBook
an honourable death
Written by MH from BRISTOL
04-Mar-2009
Well I don't know. Reading some of the other reviews I wonder whether I've just been lucky.... very trusty old G4 with its antique processor, dropped on hard floors, dragged around on trains, planes, boats and a thousand surfaces, after 6 years hard labour the battery's finally giving up the ghost. A new battery will cost about what the old machine's worth, but if it's half as good as the original that'll be plenty good enough. …More
