Simple, easy to use, and actually effective

2008-06-02
Judging from the pictures, this device looked extremely "old-school", but surprisingly it worked well. I think it's most useful to test a few batteries here and there, as it can get time-consuming if you have a bag of 100 or so. Overall, I'd recommend this because it's inexpensive and useful.

Great for the price

I looked at a few battery testers before buying this one based on the reviews on Amazon. This is a great battery tester for the price, except for one minor flaw. 3/4 of the dial is the Red ("Replace") zone, and 1/4 of the dial to the right is the Green ("Good") zone. Which means that it really doesn't distinguish too well between batteries that are fully charged and those that are about to run out of juice. I wish the display was a little more granular. But, all in all, great for the price.

It works!

This is a pretty handy little tester. The only problem I've had with it is that the opening (swinging the arm up) is meant to be done one handed, with the thumb. If you try that you end up shooting it off into the next room. Best to just pop it open with the hand you're holding the battery in and slip the battery in, letting it close automatically.

Other than that it's great. Even the kids use it.

handy way to sort out battery drawer

I saved myself some time and money with this handy, light weight
battery tester. My grandson helped me check all my "old" batteries
for usefulness. We found many that still had lots of useful life
left. The others were disposed of properly- drawer is now cleaned out!
I also took this on a recent trip - those digital cameras say change
battery- sometimes need a rest instead. Here is a way to check. It takes
a minute to get the hang of how to use it, but then it's easy.

what's not to love??

Economically priced, simple, never needs batteries, saves me money by knowing what batteries to toss and which to keep. (Also saves lots of aggravation.) I love this little sucker! Woulda gave it 5 stars but gave it 4 as it was not USA made I don't think.

Great Self Powered Battery Tester

2008-07-20
Tests all types of commonly used batteries including 9 Volt batteries. A little tricky to lift the arm up and line up the battery you are testing. So, if you have arthritis or a hand tremor this may not be the best device for you. Self powered so no battery required for operation. I bought several items together so i was able to use the super saver shipping option and not pay on shipping to make the price resonable. The tester is accurate enough to let you know whether a battery is good, low, or bad.

Enjoy !

bummer

The tester didn't work at all right out of the packaging, and was so inexpensive that I just tossed it rather than hassle with returns. The Amazon service is great, but I didn't want to bother; I needed it now, for work, so I went to the store and bought another.

Save on shipping

Radio shack sells the same product for the same price, so just buy it there and save on the shipping cost.

Simply the best

Here is what was needed: simple, robust tool to get the job done. This nails it. Not much else is needed. I went through 20 batteries this week, charged them all fully and then ran it through this tool. two were dead, so i disposed of them. It works!

No guesswork

I have used this handy tool for better than two years and it still keeps working. I have tested many sizes with accuracy. I use it to test my specialized AA camera batteries also and it has never failed me. It is small enough to fit into your pocket or camera bag. You can't go wrong purchasing this.
