Does it test CR2032 3V button cell batteries?

This tester DOES NOT work with CR2032, 2016, 2025 or any other BUTTON Cell batteies. Regardless of what is being written in these responses, again, this tester CAN NOT TEST ANY BUTTON BATTERY. The tester uses power from the battery being tested to function, the button batteries. There is no slot or contact points to test any button battery. This is not a bad battery tester, but if you need to test button batteries, this is not the product for that purpose. Hope that helps.

No, it only tests the battery, but it is the most accurate tester to detect bad cell

The battery tester works for my size 10 batteries, and depending on the brands I buy some are 1.45V and others 1.40V.

No. This battery tester will test 1.5V Button Cells up to 22.5V Lantern Cells. It will not test car batteries. -kd5-

Yes, when test button is pressed, the emergency battery kicks in to keep the light lite for a period of time.RWH

I have not used this particular product. To test batteries you need to know more than just what the voltage is, you have to know the voltage drop of the battery when a load is supplied. If your talking about a car battery places like Autozone will check your battery for free.http://hyperphysics.phy-astr.gsu.edu/hbase/electric/dcex6.html

No, it is a simple volt meter that uses the battery you are testing to supply the needed power. It has two scales printed on the face of the meter, one for button cells and one for all others.

Not sure how to test them. Two came with the purchase but, my old regular batteries would last all day.

I Would Say, No. Mine Wouldn't Respond To Holding The Test Button In Even With The Batteries Installed Correctly.

Yes. It has 9 test positions, as follows: Button Cell & Zinc Air 1.3V -1.5V, AAA-N & Ni-Cad 1.5V, AA-C-D 1.5V, 22.5V, 15V, 12V, 9V, Photo 6V, Lithium 3V

Not sure....there's 2 round button slots or testers. One for a 3V and one for a 1.5V. I have not used either of those.

A voltage meter won't tell you whether the batteries meet manufacturer specs and supply full power under load. You need a battery tester like the ZTS to do that. I just received an order of Duracells that failed that test - the second such order of CR 123 batteries from Amazon that did so. The first order was Energizer brand. I learned of the deficiency the hard way when my security system started sending off false alarms after I installed the batteries. I talked to a battery shop specialist, who said that happens when they resell factory rejects.

The power light on the right side of the unit "should" indicate the battery status of the unit, not the battery being tested. So, here's a thought, try putting "fresh" batteries in the unit, then run your test again.

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.

Absolutely! As long as you can access + and - posts, this tests almost everything, including button-style and 6-volt batteries.

Yes, just to be sure I plugged in a new Energizer AA Ultimate Lithium cell and it showed GOOD. It will test low profile "button" cells, but I don't know if it would test a 3v. Lithium coin cell due to the higher voltage.

Yes, it will charge, test, refresh, measure internal resistance of any NiMH 1.2V rechargeable batteries.
