In August 2006, discovered that some APPLE A1148 Battery do not meet our high standards for battery performance. Apple initiated a worldwide battery exchange program for certain rechargeable batteries that were sold for use with computer systems from February 2006 until May 2006.
If you follow the instructions in the manual, and cycle the battery once a week. You may have about 4-5 hours of your life acer aspire 3000 battery .I've tried cycleing the battery and it really works and makes the life of the battery. But the key is to find out once per week.
This Apple A1175 battery is terrible.I religiously-cycle battery and I get about 9 months before I up to about 1 to 1.5 hours. Unfortunately, the aftermarket is not much better. I'm glad that Apple is investing in battery technology, because these things are very expensive and suck.
I think the Apple A1175 Battery is pretty good on the MacBook Pro I was in a three hour flight the other day and my Mac battery died shortly before landing. Other PC users around me had to close because of problems with the battery for 45 minutes. After the flight was actually an entrepreneur ask me what I think questions about equipment and the battery I could not have lasted so long.
But in my opinion, this battery is extremely hot and more than one PC, which I worked or the acer aspire one battery I had until I upgraded. Therefore, be sure to wear pants or use a pillow when your notebook on your lap card! The design is great for the battery, I only have a larger fan in the MacBook to make it this cool thing.
