iPhone Battery Charging

We've all been reading about the iPhone and its battery that's supposed to last 300-400 charges. How do they define "charge"? I usually charge mine every night, when the battery is at about 50%. Is that a "charge"? If I top my iPhone off when it's at 80%, is that a charge? What's the best way to preserve the life of my iPhone battery?

Looking for the best value AA battery available (or "Let's Have Some Truth in Battery Advertising")

So Energizer or Duracell? Or some other brand? I'm confused. Apparently they are both 5 times more powerful than the other. I'm looking for the best value-for-money AA battery on the market (i.e. battery hours per dollar). I understand it depends to some extent on the device. Let's say two devices - the TV remote control - and a digital camerra. Anyone have a link to the definitive report? [more inside]

Lenovo battery failure: a cruel April Fools joke?

The battery in my IBM/Lenovo Thinkpad Z60t went out of warranty 4/29/07. When I woke up today, the machine says "Irreparable damage to the battery has been detected. Replace the battery with a new one." Is it really damaged? Could it be a broken sensor? Some kind of software glitch? Is this typical? Is there a better alternative to the $159 replacement?

Obsessive saving of documents isn't cutting it.

My year-old Powerbook G4 has acquired the habit of suddenly shutting off when it thinks it has no more power, which usually happens when the menubar item says the battery is around 30% full. Do I need a new battery? Or can I massage it into the proper sleeping/hibernating behavior somehow?

Where to buy a new battery for a 2-year-old cell phone?

Where should I buy a battery for a 2-year-old cell phone? My LG VX6100 is down to 48 hours of standby time, and I'd prefer not to get a new phone (and renew my cell carrier contract) right now. But a compatible battery does not seem to be available from a small handful of trustworthy sources, only from dozens of anonymous cell phone accessory stores. I'm wary of lousy or simply fake cell phone battery stores selling refurbished or used batteries as if they were new. Does anyone know of any reputable sources of new cell phone batteries for old phones? [more inside]

Replacing batteries

On a device with 2 batteries, say for an example, a remote control with 2 AA batteries, the instructions for the device say, when the time comes, to replace both batteries, not just one. As if replacing one battery, while it will supply enough energy to run the device, will somehow damage the device. Is this just a ruse to sell more batteries?

Apple iBook G4 Battery Problem?

My iBook G4 has lately been winking out, for no apparent reason, as I'm in the middle of something (I have to reset the date each time, among other things). The weird thing is that it only seems to happen when I'm on battery power. When I press the little button on the bottom, it seems to indicate full power. However, I was noticing a month or so ago I was getting weird battery warnings -- saying it was almost out of power, when it said there was 41% power remaining, etc. Has anyone had this problem, and might a new battery somehow be the solution?

How to clean up a battery leak in a flashlight

When trying to change the batteries in my maglite after a long period of neglect, I found that the cap wouldn't unscrew. After persuading it open with a pair of mol-grips, I could see that one of the batteries had leaked and there was a big grey corroded-looking stain on the inside of the battery compartment. Is there any way I can clean this up, or should I bid farewell to my trusty torch? The battery is a D cell alkaline.
