Last Thursday, my 2008 Scion xB had its alternator die. I picked it up yesterday from the mechanic, and a new alternator and new battery later, it runs fine, except for one thing: it gets a case of the shakes like it wants to conk out when it is idling. Could this be related to the aforementioned alternator problem, or is it something else? [more inside]
I wonder if having 4-5 Word files open (including 2 always, just for for convenience) will drain my Dell Inspiron 11 3000 series battery quicker than just using one file at a time. I wonder: Does more tabs being open in a broswer mean more battery drain? Is a nonactive YouTube tab best being closed till used? I wonder if even having calendar, weather -- stuff I seldom open -- pinned to my taskbar run the battery down more quickly. Same question regarding having several Adobe Acrobat Reader PDFs ready at hand...just comic book pdfs. These things take so little space on the hard drive, so I figure they'd also use less RAM than other actual heavy programs, thus would be easiest on the battery-time availability. Correct me if I'm wrong, but having Foobar, Windows Media Player, and Spotify open at the same time will drain battery faster than having one going, as well as slow things down generally? Add to that the Word, Acrobat, a broswer... Thanks.
I just finished reading The Powerhouse by Steve Levine and it inspired me to be curious about the specific lithium battery chemistry of current cell and smartphones. I've found this link from Battery University which does a great job describing the current major variants used (LMO, NCA, NMC, etc). In some google searching I haven't found any specs on what phones like the Nexus 6 or the S6, or iPhone 6 uses. [more inside]
We are getting to the time of year where I am going to have to start mowing the lawn. Our old reel-style mower died at the end of last year, and it kind of sucked anyway. I do not want to mess with gas. Do you have an electric lawnmower, either corded or battery powered? Is it great? Is it terrible? Please tell me about it. [more inside]
My car (2012 BMW 328i xDrive Wagon E91 LCI) has two quirks: 1) battery warning after turning off the car, even after extended drives (never BEFORE starting the car) 2) brake wear warning after car has been parked in the cold for several hours (disappears after warming car up) [more inside]
I have a 2007 Mazda 3 with battery problems. I'm looking for: 1. Any thoughts as to what the underlying issue might be (and how expensive it should be to diagnose/fix); and, 2. Recommendations for anglo mechanics in Montreal (specifically Verdun, ideally). [more inside]
I have to jump my car almost every time I drive it in the wintertime. Help! This is not fun at all. [more inside]
Twice in the last 6 weeks, our car wouldn't start without a jump. Rest of time it's fine. Should I buy a new battery or is it something else? [more inside]
Help me diagnose, because I'm not convinced that it's because the battery is completely/irreparably fried. I am computer hardware naive but would prefer to explore all diagnostic possibilities before purchasing a replacement battery, especially if that won't fix the issue. [more inside]
Dead six-year-old car battery last night. Replace? [more inside]
My 3 year old Dell Latitude E6420 laptop needs a new battery. It had a replacement already about 2 years ago after the one it shipped with just fell out one day (!) but other than that has had no battery problems. Anyone know how I can get a reliable replacement **here in Germany**? I would ideally like a Dell or Dell-recognised component as this is my primary device and it needs to be reliable.

Hey, all. I have a three-year-old Gateway laptop (NV55C) that was having battery problems, so I bought a replacement battery from Amazon. When I got the replacement battery, it included a list of battery models it replaces, and the model of my old battery was not among them. Is this bad? [more inside]
I got my samsung galaxy s3 15 months ago. My phone has been acting up lately - been very slow to charge and even after being fully charged goes down within 10 minutes. Now my phone say that it is charging but only reports 0%. I've had it plugged in for several hours with no change. I then turned off my phone and then removed the battery and put it back in again. Currently can't get to a Verizon wireless store and traveling. Was wondering any means to self diagnose the problem until I get to a real store next week. ANY ADVICE WOULD be HELPFUL. Thanks in advance!

Just went out to the family car to find it has a flat battery. Such a lovely day outside, I really don't feel like jump starting it, and I don't need it today. However, I was speaking to my father (who's overseas, I'm house sitting) and he'd prefer I do it today as car batteries shouldn't be left in an uncharged state as doing so does damage. Is this true?

My cheapo Android tablet finally gave up the ghost. I'm in the market for a new, nicer one and thought about getting the Nexus 7*. But searching around, it seems to have a lot of problems with battery life, even when on stand-by. I don't play games or watch videos or even listen to music much on a tablet. My main use case is reading and annotating pdf articles and books, especially when traveling (long flights) when battery life is kinda important. Are these battery life concerns for the Nexus 7 founded? Is there another Android** tablet that does better? [more inside]
Phone battery won't hold a charge-what can I do? [more inside]
I have a Lenovo Ideapad Z470, and the battery is pretty shot. I've been unable to find a replacement battery for this model through Lenovo's own site. I also can't seem to find an exact match for the one I have through third party selling. Current battery: labeled Li-ion 20, model # L09S6Y02. Closest match I found online, which claims that it's compatible with my laptop (but I could find no actual evidence): Li-ion 00, model #L08S6Y02. Put my mind at ease, Mefites: is this new battery compatible with my laptop? (And if I should return it, where should I get a battery, because searching Amazon for this kind of thing has been annoying.)

Right now I'm at the airport, waiting to fly into DC, and just realized I forgot my charger. I'll see what I can pick up at my layover, but I would like to a) not fry my laptop and b) continue to use my laptop. I would like to buy the charger after checking into my hotel. I will not have a car. Relevant facts: 1) The X220 is the small Lenovo Thinkpad (not touchscreen.) 2) Staying in Dupont Circle 3) No car

I have an 8-GB Nexus 7 that's about a year and a half old. Its battery life seems fine, but the actual charging takes an unreasonable amount of time. When it was new, it charged in about 2.5 hours; last night it took 7 hours to go from 30% to 60%. I'm using the adapter and cable that came with it. Is there anything I can do to make my device charge faster?

I bought my iPhone last February. During what remained of that Winter, I would take it with me when cross-country skiing, walking outside, or taking the bus to work. It seemed to operate just fine, as had my prior phone which was a Samsung. This Winter, however, the cold weather seems to be seriously affecting the phone's battery life. The battery drains quickly when I'm outside and sometimes suddenly goes from 20% or more to dead. Today, I went out skiing with the phone. I was listening to a podcast and using an exercise app to track my speed and distance. When I started out the phone had 55%, but it died after only 10 minutes. The temperature was -10F/-23C. I've also had it drain quickly after waiting to catch the bus. Is there anything I can do to solve this problem and continue to use the phone in the Winter? Is this something the folks at the Genius bar can help with? Should I create some sort of insulated pouch for the phone? I realize that temperature can affect batteries, but I'm surprised because I didn't have this problem other winters. I know I've taken phones out in colder weather than today without such a sudden failure.

I'm trying to find a replacement battery for my Panasonic Lumix camera in south Austin, TX.

No time for ordering, I need to find something and pick it up tonight. Thank you for your help!

I'm helping an older gentleman get going with his first smart phone. He is traveling without a car, camping without power, battery consumption management on the phone is CRITICAL. The app needs to FIRST be simple to setup and use, second allow him to easily see what is using the battery, and third have tools to kill wasteful usage. Free would be nice, but willing to pay for a SIMPLE app that does what he needs without confusing him with bells and whistles. [more inside]
Our chickens [!] have trouble hopping up on their roost at dusk. We have glued a keychain LED to the inside of the coop and have been turning it on every night, and then off when they are roosting. I would like to have this turn on automatically at dusk and then off again an hour later. If this were AC I would buy a timer from the dollar store. For DC do I need to build something? [more inside]

I have a 2010 Ford Fusion and a lot of electrical gadgets which plug into the cigarette lighter. The car I previously drove (for over ten years) had a cigarette lighter which turned itself on and off with the ignition. The Fusion, however, leaves the lighter socket on all the time. Because of this, I sometimes forget to unplug things from the cigarette lighter and end up with a dead battery after a day or two with the car parked. Is there some relatively-easy way for me (or a mechanic) to re-wire the cigarette lighter so that it powers itself on and off with the ignition? If so, how? [more inside]

I have this type of watch. The manual suggests that I should get Timex to repair the battery. I'm hoping to be able to do it myself and save a few bucks. However, I don't really see any way to get the back off. I also want to adjust the band as it's too large for my wrist. But, again, I really have no idea how to do this. Hoping someone here can tell me if this is something I'd be able to do from home (and tell me how to do it) or whether I should take it to a jeweler.
I recently acquired a new MacBook Pro, with a retina display. It's a sealed unit, with no user-replaceable battery, so I'm obviously interested in maintaining the battery life. I noticed that the new T-shape mag safe connector is not very grippy, and falls out all the time. So I called Apple to see whether the constant unplugging/plugging was a bad idea, and the rep actually said at one point that it was a bad idea to keep the laptop plugged in when it was charged (with the green LED showing in the adapter). I confirmed that this was what he was saying. So does anyone know if this is true? Because I've always kept my laptops plugged in, all the time. [more inside]
