The average family spends hundreds-of-dollars a year on expensive replacement batteries for the dozens and dozens of battery-powered devices in their home. Unfortunately, many of those batteries are wasted simply because you can't differentiate between 'good' and 'bad' batteries just by looking at them. When a battery-operated device isn't functioning properly, we first replace the batteries with new ones. But if the device still doesn't work, both sets of batteries tend to end up in the 'unknown condition' category. Then the next time we need fresh batteries we open a new package to be sure we're getting fully charged ones--the Unknown roll around and bump against each other until even perfectly-charged batteries have gone to waste. Here's a better way for your pocketbook and the environment: simple-to-operate, instant & accurate battery testing with a sophisticated digital device small enough to carry in shirt pocket, purse or car. Tests virtually any replaceable battery type and size: AAA, AA, C, D, CR123 and other camera batteries, 9 and 12-volt, button-type for watches, hearing aids and remote controls, Alkaline, non-Alkaline and Lithium. 3-1/4"L x 1-1/2"W x 5/8"H, 4 oz.
