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?

Is anyone else having trouble with Apple's most recent G4 powerbook battery recall program? [more inside]
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?

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.

Power Inverters for cars - the thing you plug into your cigarette lighter, with a regular wall-plug on the other end. I bought one last night, for use with gadgets on a road trip. Thing is, they offer two types, excuse the B-st B-y links: this one (95W), which I bought, and a stronger one (150W) here - Question is, I went with the smaller cheaper one but I know nothing about power use for things. Should I return it for the larger, or is this sufficient power to charge a laptop, camera, PSP, ipod, etc? Mostly concerned with safety to equipment and car's electrical system.

I'm sure somebody else who's travelling over Thanksgiving could also benefit from this knowledge. I brought my cell phone with me on my five-day trip to my parents' place, but of course I forgot the charger. The question I ask is: 'tis nobler to leave the phone on continuously and hope the battery pulls through, or is it a better idea to turn the phone off every night and turn it on only at the point in the day when I plan to use it? Does powering off and on drain more battery power than idling / the cell phone equivalent of "sleep"? FWIW, I have a relatively new Nokia 6682, and the battery is currently showing a full charge but I suspect it's lying, as I think it's been at least 24 hours since I charged it (that said, this battery's done five days unplugged before).
Battery power cycling - it's offered as advice for poor battery life on pretty much anything, from cell phones to laptops. Heck, T-Mobile told me to do it today after I switched phones and the same battery dropped from 50 hours of standby time to 9 hours. However, I've only ever cycled one thing - a laptop battery - and that dropped its capacity from 4 hours to 30 minutes. Because of that I'm a bit wary, so my question is, what's the logic behind power cycling a battery, and has anyone actually seen any benefits from it?
PotentiallyStupidQuestionFilter: I'm looking to juice up my long-in-the-tooth titanium Powerbook (from March of 2002 -- 667 mHz processor, 512 MB of RAM, 30GB harddrive, etc.) with both a new battery (since the original one now gets approx. five minutes of life when unplugged) and OS X 10.4. Here's the weird question: Should I put the battery in first, and then update the OS, or do the OS update and then swap in the new battery? It might not matter at all, but I know that operating systems do have an impact on battery performance -- is that something I should be taking into consideration, or can I do either upgrade at any time without worrying about sequence?
