I have heard that you shouldn’t mix old and new batteries. Why?
—Gretta Golyansky, Aurora, Colo.
As the weakest battery dies, power surging through it from much-stronger batteries may cause it to leak and ruin your device. In rare cases, an airtight or waterproof device—such as an underwater flashlight—may even explode if ignited by a nearby spark or excess heat. The risk also is present if you mix different types or brands of batteries or insert them backward so that their polarity is reversed.

13 Things You Can Get For Free
After a bit of searching, we uncovered a bunch of 100% discounts hiding in plain sight. In many cases, the only effort that's needed to claim them involves the 15 seconds it takes to type in a name and an e-mail address.
Free flicks and shows: Instead of spending $2 at the iTunes store for an episode of "Family Guy" or $10 for the movie "The Big Lebowski," go online to Hulu and get them free, for viewing on your computer. Hulu's inventory of 100 movies and 400 TV shows includes titles from Fox, NBC Universal, MGM, Sony Pictures Television and Warner Brothers. (See "Kill the cable box: Get free TV.")
Sports gambling: Online gambling has always been illegal, even though people got away with it for years. CentSports.com skirts this pesky problem by bankrolling its customers. Users start off with 10 cents in their accounts, provided by CentSports, and use it to bet on any event for which Las Vegas bookmakers set a line.
Accumulate $20 in winnings, and you can cash out a minimum of $10 (sent by check in the mail). Losers risk nothing and get immediately re-staked with fresh dimes. (For more on CentSports.com, check out "A legal alternative to online gambling.")
Free tunes: Napster is no longer free, but there are legal alternatives to downloading free music. One of them, Spiral Frog, offers 1.2 million songs and 4,000 music videos. To sign up, you need only provide e-mail and mailing addresses; no credit card number is required.
For a better, more customized radio experience on the cheap, check out Pandora.com. Just enter an artist, and the site will generate playlists from that band and others within its genre. Better yet: There are no commercials.
