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?

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.
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]

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?

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?

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,

Interested in a Netbook or lower power laptop that runs cool (doesn't require external cooling like this) 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?

Is my ipad2 up to the job? I have to give the same hour-long presentation in three separate sessions in one day. I am planning to use Keynote on my ipad2 attached to a projector but I'm worried about battery life on the iPad. Does anybody have experience using their iPad in this way? I will of course, turn off every battery draining thing I can find. I could also switch to my iPhone 4S if I had to, I guess. Will I be okay for three presentations?

I'm trying to resurrect an old Casio CPS-85 88 key keyboard. When it was given to me, the power jack was cracked, so I desoldered it and soldered on a new one. No luck; I can't get power (even with a different power supply). So I'm stuck running off of a lot of D batteries. As using D cells is both wasteful and expensive.is there any way for me to rig an external power supply to the battery terminals in a safe manner?
Follow up to previous question....4yo Dell Inspiron laptop suddenly giving me the old "Plugged in but not charging" routine. Froze the battery for a day but no luck.
