Is it at all possible to test button batteries (e.g., CR2032) with any degree of accuracy, either singly or in pairs, on this unit?

No, I don't think that would work very well as there isn't a test point for 3v (if that's the voltage of the cr2032)

Sorry, I don't know. It does have a small corded attachment that looks like it might. The attachment looks like a small stylus with a metal point.

Thge only thing I can think of is that there are + and - marks as to how the batteries should be matched to.

Sorry, but this tester is for "bare" batteries rather than multi-cell battery packs. It's the best tester there is for what it does, but isn't designed to test dedicated camera battery packs and the like.

As far as I know, no. To test the charge, it is executed a discharge/charge cicle. It would be possible to test the volts of the battery, wich is reliable mesasure for non-rechargeable batteries, but I presume it would be dangerous.

My spare batteries are all CR2032.. the device is about 2 months old.. works fine.. the transmitter apparently uses a different battery (12 volt). The device works well.. just be sure to hold down button for couple of seconds to give it a chance to set up the frequency and get a response.

Hi, thank you for contacting us. I'm afraid the tester can only perform test when component is NOT in circuit. With best regards, Kevin

M_ENGLE and DUSTY comments contradicts what Bob commented...I want to use this device for load testing and confirm the condition of any battery......who am i to be believe now, because am about to place order.

No. I tried the same thing. But there is circuitry to prevent overcharging which would damage your batteries that is missing in the circuit.

Yes you can, and also record the voltage that the battery contains. Although this unit is meant to do much more than that, and there are other less expensive multi-meters or battery testers that can give that type of information.

Mine have a CR2025 in them and they work fine. Specs on back say 3.0v button battery.

The batteries in mine are labeled as AG13, but I connected a battery pack of 3 AAA's to mine, so I haven't tried to find replacement button cells.

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.

I have not used a voltage meter on the battery to test the accuracy of the battery tender. I just know that the tender works for me.

You get the best indication of battery condition under load. All this tester does is provide a load and measure voltage. I expect it wold work fine for your deep cycle batteries.

I'm not sure as I have only tested standard batteries but I think lithium can be tested as well.

Who knows how accurate these cheap gauges are... Checked mine with my analog meter: slightly more than 12 volts at the battery - perhaps 12.1 or 12.2. 12 volts at the terminals on the back of the gauge while the gauge read a hair more than 12. Yours might be different of course.

I don't think so. I looked in several cross reference charts for batteries and they are not mentioned as being compatible. Additionally a CR2032 visually appears to be slightly larger than the CR1632, but I didn't have a CR1632 to make a physical comparison.
