Maximizing Laptop Battery Life?

My 1.5 year old MacBook is my first brand new laptop I've ever owned. My previous two were pretty used and battery life sucked. On the rare occasion that I use battery power I get between 3 to 4 hours of life if I'm just web browsing and have everything turned down for minimal power consumption.

My questions is how can I keep my battery maximized to keep this long battery life? Someone told me every month or so I should drain the battery completely and leave it dead over night and then fully charge it. Any truth to that?

I normally keep the battery fully charged wherever I go and rarely use the battery unless I have to. Does this hurt battery life? Should I periodically (more frequently than draining the battery completely down) use the battery and charge it back up even if I don't have to?

Finally question. What laptop do you use and how long does it normally work just using the battery?

my dell laptop battery doesn't hold a charge anymore, because i just used to keep it plugged in all the time and never let it drain. you do periodically need to let it drain all the way down and completely out and let it sit, then plug it back in and completely charge it again. although i would do it 3-4 times a month. laptop battery technology sucks and they easily develop a "memory" so to speak. although macs for some reason seem to be better than pc's, they are still fully capable of going south in a bad way.

I'd first recommend getting a small laptop stand that lifts it off your desk about an inch or so. That'll help out quite a bit because it'll keep the battery cooler. I'd also say to plug it in when you're down to 25% battery life or less. Don't keep it plugged in all the time, cause when you do the battery is constantly charging and staying hot. You can actually overcharge a battery. Letting it run all the way down once a week is a good idea too. We've got an old Powerbook G4 and we've only replaced the battery once since 2004. Currently my younger bro uses the laptop and he can go pretty much all day using it on and off without having to recharge it.

Over five thousand years ago, Moses said to the children of Israel, "Pick up your shovel, mount your asses and camels, and I will lead you to the Promised Land." Nearly 75 years ago, Roosevelt said,"Lay down your shovels, sit on your asses, and light up a camel, this is the Promised Land." Now Obama has stolen your shovel..., taxed your asses, raised the price of camels and mortgaged the Promised Land!

Dim the screen, turn off as many processes as possible, turn off the wireless card if youre not using it. disconnect any usb devices.

There are apps out there (my IBM lap has one) that'll stop the batt from fully charging EVERYTIME and it'll also stop the battery from continuing to be charged when it is full.

My HP does this automatically. You can see it will switch from charging to running on AC. I can watch one DVD (a little over 2 hours) on a full charge or work for about 6 using the internet tethered via USB to my PDA or just working on local apps. Make sure your hard drive is not set up to continue running if it's left on and not being used.

My 2 year old Dell M700 will go for about 4 hours before I get a warning to charge it. Best laptop I've owned yet for battery time.
