Choosing the Right Battery (1/4)

This is what happens when you take two dozen noisy, battery-powered toys, turn them on and watch them go.
It's a parents' nightmare.
24 loud, obnoxious toys running wild for hours on end.
And it's driving us nuts.
But it's for a good cause.
When it's all over, we hope to know which batteries really keep on going and going and going.

Which batteries are best?
You may not spend a lot of time thinking about batteries, but chances are you spend a lot of money buying them.
Americans purchase over two billion batteries a year.
And choosing the right ones can be confusing, thanks to a blizzard of claims from competing brands.

Recent tests prove that Duracell outlasts Energizer.  

Energizer really does last over 30 percent longer than Duracell in these digital cameras.  

Get the Maximum. New Rayovac Maximum.

You watch the ads, then every one says they're the best.
So how does one, how do we, the consumer see through that?

Well, I'll tell you. It doesn't matter.

Retired engineering professor Dick Costello says there are some differences among alkalines, the most popular type of batteries.
But those differences, he insists, are too small to matter.

You can go and buy an Energizer or a Rayovac or a Duracell or a Radio Shack or a Sears battery, and they'll all last very close to the same amount of time.
The differences are probably going to be 10 percent or 20 percent.
If the price difference is more than 10 percent or 20 percent, go with the cheap price.
