I recently upgraded my cell to a Galaxy S7 Edge. My previous cell phones had removable batteries, and I preferred keeping a fully-charged backup battery on me or swapping batteries out and charging the batteries separately. The new phone has no removable battery, and I would like to make sure I'm charging the battery in the best manner possible to prolong the life of the phone, but my google-fu is turning up some conflicting information. Please help me figure out an optimal charging method to avoid shortening the battery's lifespan. [more inside]

Workmen just came to my new apartment to remove a broken washing machine. After they left, I found a crushed AA battery where the machine was left. I have no idea how old it was or if they crushed it moving the washer. There was liquid on the floor, but that could have been from disconnecting the washer. How do I clean this up safely?

I've just moved into a new (to me) house. (The house itself is old and quite funky.) I brought with me my extant Macbook Pro (most-recent vintage). I'm finding that when my computer is fully charged and the charging cable is plugged in (green light), the house lights flicker. [more inside]
I got a new Nexus 6P the other day. Part of its appeal was all the reviews said the battery life was really good - and would last approx a day and a half with sensible usage. But for the last two days, I have come to work with it charged, listened to about an hour of music with the screen off on my commute, then left it on my desk, hardly used it apart from checking a couple of messages and yesterday it died after 11 hours, today after 11 hours it's down to 12%.

I live in Toronto and my neighbourhood has above-ground powerlines and lots of trees. We get blackouts every year, usually from something happening at a transformer station, but during the ice storm it was because of trees taking out power lines. If I want to protect my family and house against power outages it seems like my options are either getting an installed generator, a portable generator or some kind of backup battery. How do these compare, and is anything going to change much in the next couple of years? [more inside]
I'm looking for the best product - case or wallet - to boost the battery life of a Samsung Galaxy S6 Edge. My previous Galaxy had a removable battery so this was easy, but the sealed design of the snazzy new models means I need some options. [more inside]

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]

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.

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. 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!
