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. THANKS FOR YOUR ADVICE. [more inside]

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?

I have a third generation ipod with the now-infamous crappy battery that falls just outside eligibility for the lawsuit reimbursement. All ranting aside, if I spend the $59 to get a new battery, is it actually going to last any longer than the lame original? Or am I better off investing in a new player altogether?

A lab I have recently taken over has a box full of obsolete batteries, mostly for various video cameras stretching back at least to the late 80s. I assume these are mostly lead-acid or NiCad. I don't have the cameras anymore. The batteries are intact, but I would like to dispose of them properly or find out if they can be recycled. Any ideas?

My battery acts funny. It always says I have over three hours when it first gets charged. Then after just a few minutes it says much less, like an hour or so. Then within minutes it is off. I have charged it completely and let it drain to completely of which I have been told resets the power manager. Do I need a new battery? If I do, are any of the after market batteries better than the Apple battery? The computer is two and a half years old.

I recently replaced the battery in my old Dell Inspiron 4000. Today I noticed that the led on the power adapter goes off if the battery is in the machine and the machine says it is running on batteries. If I unplug the battery the computer turns off. I am able to boot on AC power but the moment I insert the battery the adapter stops working. I think this is new otherwise the battery would've drained days ago. Has anyone encountered this before? Any ideas? Also, if the computer is off and I plug the adapter into it while the battery is also present, the led on the adapter goes out. If I then remove the battery and attempt to boot the machine, nothing happens. This is very weird. [more inside]

iPod help: My 5-Gig, Touchwheel iPod is hung and displays the following message: "No battery power remains. Please connect iPod to power." However, the iPod had 2/3s of a charge before it hung and does not accept a charge when I plug it in. I am unable to reset the iPod and it refuses all keyboard input. It has displayed this message for almost two days now. The iPod also does not register in the Finder of either of my computers. Should I buy a new battery or is the iPod dead?

I have a laptop (Sony Vaio R505) with a lithium ion battery. Last night, I used the machine fine with out it being plugged into the wall (for about 2 hours). Today, when I tried using the machine after a full charge, it died within half an hour. I'm currently using XP with SP2 and google'd all the user groups. Any suggestions other than buying a new battery?

Is there anything I can do to make my laptop battery last longer? I've had two HP laptops, and within months the batteries in both of them stopped holding a full charge. Presently, the icon indicates a fully charged battery, but when I unplug the laptop the battery dies within 30 minutes. Is this an HP specific problem? Is there a "better" kind of battery I can buy?

I'm considering buying a new laptop battery and after scouring the web and usenet, I can't find any definitive word on aftermarket batteries. This thread
essentially says they're both good and bad, as does this one
I've made a lot of purchases of refurbished equipment, but batteries have always been something I'm wary of. I've seen pretty solid recommendations of igo.com
and Eagle Imports
(whose batteries completely dominate the ebay laptop battery market
), where they frequently sell for less than half the normal retail cost.

I'm having problems with an 87' Nissan truck (5-speed). Recently when its been sitting for a day or so, me engine doesn't want to turn over at all when I turn the key and all I get is this "click" sound that is identical to how my old car sounded when my alternator went out. The thing is, if I turn the key a few times, it'll start and its fine for the rest of the day when I try to start the car. This "clicking" thing has happened a few times now, and I don't think its the battery (lights and everything work perfectly, and no problems with engine turning over when no click sound). Any ideas what might be wrong (gut instant says alternator is going, but just seeing if any other ideas).
