Customer questions & answers

Question: Will this work on Energizer Lithium batteries?
Answer: Works with any battery once the negative and positive points of the battery can make contact with the respective points on the device including by wires.
Question: Will this work on Energizer Lithium batteries?
Answer: Yes!! This works on every battery I’m pretty certain, great buy.👍
Question: It says 1.5v button batteries. What about 3v button batteries? Does it test them also?
Answer: Yes it does.
Question: Does this accurately test ni-cd and NIMH batteries?
Answer: Yes. I test ni-mh and alkaline batteries all the time and both can be tested on this tester. 
Question: How do you test button batteries? Can’t get a reading on any of them. Is there a special angle?
Answer: Just make sure that the positive side of the cell faces the red button of the tester and close the battery and read the appropriate scale on the tester. I routinely test various button cell batteries and have never had a problem. Hope this helps, have a very blessed day!
Question: Does it charge li-ion batteries?
Answer: It doesn't'charge'anything. It's a tester. It'tests'the stored energy level in batteries.
If something isn’t working you can at least eliminate the possibility that the batteries are depleted.
