Portable DVD players can provide a great source of entertainment on long trips, especially to keep kids from asking the dreaded question, "Are we there yet?" However, if your batteries die in your player, its value dies along with it. What you need is the longest-lasting battery you can find for your player.

Types of Batteries

Alkaline batteries include the standard AA, AAA, C and D batteries from companies such as Duracell or EverReady. They're inexpensive (relatively speaking), but portable DVD players tend to suck the life out of them quickly.

One way to remedy that is by purchasing rechargeable alkaline batteries. Make sure to have several spares handy. Watch out for nickel-based batteries that lose some of their ability to recharge after going through several partial charges or discharge cycles.

The top-of-the-line batteries nowadays are lithium-ion. They have the longest lifespan without losing their ability to recharge.

Longest-Lived Batteries

Check your owner's manual to your portable DVD player to see whether it takes only standard alkaline batteries or is compatible with lithium-ion or nickel-based batteries.

You also can look into buying rechargeable battery packs that provide anywhere from four to 20 hours of viewing, depending on how much you're willing to spend. These battery packs plug into the 9V to 12V input jack of your portable DVD player and can substitute for when you can't plug directly into an electrical socket or the car outlet.

Future of Portable DVD Player Batteries

Most batteries for portable DVD players don't last very long because of the amount of power needed to run the device.

Scientists and engineers are working on ways to solve that problem. Four years ago, scientists at Arizona State University announced their work on a fuel cell small enough to use in portable electronics such as DVD players, but with three to five times longer life.

This year, scientists unveiled another possibility -- a biofuel cell that would recharge with the sugar found in a can of soda or a bottle of vegetable oil. These technologies are still years away from being viable in the marketplace, however.
