Intuitive, easy to use, solidly built
September 15, 2014
For a long time I've been approximating battery health using an ordinary multimeter, which wasn't doing the trick for a couple of reasons:
1) a standard multimeter does not put the battery under load, so voltage readings using one are not really a good indicator of battery strength; and
2) it's tricky to consistently touch both terminals on a AA or AAA battery with multimeter leads unless you have three hands ;)
This battery tester solves both problems in a small and solidly built package. Using it is very simple... all you need to do is touch the positive battery terminal to the appropriate button on the tester, and then touch the attached lead to the negative battery terminal for a couple of seconds.
Occasionally a battery will wake up a little after the first reading, and show slightly higher strength in the second or third test. Nonetheless, I've gotten very consistent readings using this tester, and it's made it very easy for me to weed out the dead/dying batteries around the house.
My only (minor) criticism is that the readout shows battery strength in blocks of 20%, so I'm not getting highly detailed information. However, I knew this was the case when I brought it, and this UI is more than sufficient for the intended purpose.
