There are hundreds of inexpensive devices that say battery tester, but they DON'T DO A DARNED THING. They are just little voltmeters. YOU CANNOT TEST A BATTERY WITH A VOLTMETER alone. YOU CANNOT TEST A BATTERY UNLESS IT IS UNDER LOAD. To test a battery with a voltmeter requires other items and knowledge of what you are doing.
If you want a battery tester, and it doesn't say it tests under load, and you can't figure out whether it does or not, don't buy it. A simple voltmeter is useless as a battery tester. Even a $400 voltmeter not specifically designed to test batteries is useless as a battery tester.
If the tester is under $20, there's very little chance that it tests a battery under load. The Ansmann 4000042 does.
I also saw the ZTS Mini Battery Tester - ZTS MINI-MBT that looked good, but it was around $40 and I didn't need to test all the types of batteries it handles.
I give this tester only 4 stars for two reasons. First, it tests only one parameter of a battery. But, it is the key parameter. Second, it is slightly clunky to put a battery in it to test. So slight, that it is probably not even worth mentioning.
Would I recommend this tester? At less than $20, and for general household use, most definitely.
I also owned the ZTS Mini 9R Battery Tester which also tests a battery under load. Between the ZTS and Ansmann, I prefer the Ansmann. Though the plastic material on the ZTS is more durable, the use of the probe and having to balance a battery on little nubs makes the ZTS awkward to use.
As for this Ansmann tester, it tests the common sizes (AAA, AA, C, D and 9V). On the front there are two scales, one for rechargeables and the other for 9V/alkalines ( "primary"). Both type of batteries light up the same green led lights but depending on the type, one needs to refer to the appropriate scale (above or below the leds).
Compared to most inexpensive testers, this is a large tester. More about the size of an old incandescent bulb, but flatter in the bulb area. Testing for the most part involves placing a battery in place and then sliding the halves (top and bottom, help by springs) together to make the proper contacts. I say for the most part, as the tester best tests size C and D batteries. 9V batteries requires lining up the negative and positive contacts. The inner center area are for AAAs.. But one has to make sure the bottom of the battery is indeed touching the bottom contact as I've found myself having the battery touch a plastic area and having to adjust.Read more ›
I'm not sure if mine was defective or a bad design.
It uses a 9v battery to power the tester and after 2 weeks of sitting with the battery installed, the battery was dead.
I installed a brand new 9v battery that read 100% charge. 2 days later the battery showed 75% charge.
Based on this, I would not recommend this tester.
