Excellent Product... Essential Battery 'Tester'
This is an ESSENTIAL, Well Designed Product and everyone who uses batteries or has battery-operated products (all of us) needs one otherwise, you have no idea of the charge-status of your batteries... and don't just assume that batteries are always fresh with full-charge right out of the package or fresh when shipped/supplied with a battery-operated product. I have owned/used several battery-testing products and this one is by far the most versatile, convenient, quick and easy-to-use. Always TEST (even new) and DATE batteries (mo/'yr with a fine point 'sharpie' pen) at the time batteries are put into service in a device/product. Fortunately, manufacturers are trending towards more rechargeable batteries, but until then we all need our own battery 'tester' to know the charge-status of our batteries. This battery testing product is quick, easy-to-use and accurate... I use mine frequently and I would repurchase.

Easy to use
Very handy! Wondering why I did order this sooner. Simple to use for all sizes. Price point is right on.

Solid product for the price
Works as expected. A tad difficult to pop out AA batteries--could be designed better for that. Love the numerous battery types supported and highly usable and intuitive design. Note that this is a relatively cheap product--it does not put a load across the battery to allow you to determine if the battery can really hold its displayed voltage under a typical load. You are basically getting a quality product relative to the cost.

Battery Tester
So far I like everything about the meter, it tests AA, AAA, 9volt and button cell batteries. It doesn’t just show you if your battery is good or bad but also show the degrees of charge the battery has left so you don’t have to guess if it is still good or not. It also comes in a variety of colors which I like. It is a nice battery tester.
