New (6 month old) car battery has died twice in the past month. From the pattern it's been showing, can you help me figure out what the issue might be, and help me avoid getting swindled in my attempt to get it fixed? [more inside]

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.
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. The camera is a relatively new model (DMC-FZ200), and I'm having a hard time finding local stores that might carry the battery in stock. The battery is a DMW-BLC12PP 7.2V, 1200mAh/8.7Wh Li-ion. 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]

Greetings - I "inherited" a MacBook Pro last year. It was a Apple MacBook Pro Core 2 Duo 2.4Ghz from Spring 2008. So it was 4 years old when I got it and I was told that the battery was dead and as long as I kept it plugged in, it worked fine, however, I would need a new one. So last year, I purchased a new battery and installed it.
However, I am still noticing that the battery life is horrible. It seems like when I am using it to type a document or check emails and surf the web, etc, I literally can watch the battery drain. I would assume that it might hold a charge of about an hour and a half maybe?
Is there any way I can "test" it to see what my actual battery life if? To ensure there isn't something else going on? Any suggestions would be helpful. Thanks,

Car was starting intermittently (power to the dash lights, etc., but zero activity from the starter) as the battery reached the expected end of its life. So, new battery. Same problem. The shop that has the car tells me that a new battery sends a relatively high amount of power to the starter and that this can cause problems with it (gears, etc.) This doesn't sound ludicrous, but I know enough about cars to know how much I don't know. Here's hoping the knowledgeable people (for whom I have vast respect and gratitude) 'round here can share their thoughts. Thanks! [more inside]

) and has long (6-8 hour) battery life. Would like to run Windows 7 so Chromebook is not a good candidate for me. And of course want to come in around $200. I know there a lot of candidates here but would really appreciate user's real life experience. Thanks.

I have an older MacBook I use when travelling (four or five times a year), and then the odd occasion when I am away from my office desktop. The battery on the MacBook died a few months ago, and I am guessing partially because I haven't been using it frequently enough. I am hesitant to replace the battery, figuring the same thing will happen again, is that right? Is there a downside to not having a working battery on the computer itself? And lastly, is there a problem with leaving the dead battery in the computer?

I suspect that unscrupulous dealers buy used Lithium-ion batteries, reset or replace the circuitry so that the capacity and charge cycle count are as-new, and then resell the batteries as new. How can I collect evidence for or against this hypothesis?

Bought my used 01 Toyota Camry from a dealership over a year and a half ago. Today they inspected the brakes and told me all pads need to be replaced + new brake fluid + powersteering fluid flush + resurfacing the rotors, and new battery. I have been taking this vehicle to same dealership for routine oil changes which include multi-point inspections, and only the battery was an issue in the past. Am I wrong to think that after just over a year and a half I shouldn't need so much work done- should I complain and write a letter, or is this to be expected with a used vehicle? [more inside]
