How do you take the compression band out?
On units like this one, how do you set it to test a 3.7 volt?
Im inclined to get the simple one from marble vapors. I had one made by klein , the mm200 ? It jumped around, and I never got a steady reading, maybe it was my hands? But I thought I had it down and compared it to the little black carto/ atty ones and I was way off.
So, something like this would not work?
The big center dial is adjustable to test different ranges of volts and ohms. Basically, the dial moves the decimal point left or right as you turn it, dialing in what you're trying to measure. As it's pictured, it's set to test battery voltage for the batteries we use for vaping. Really easy to use, inexpensive and versitile.
i have this but it does mot seem to have a 3.7 v setting
Guess i will have break down and get a multimeter.

On that note, what if one dropped a brand new battery and the skin of the battery got a tiny nick. Im real low on batteries at the moment and hate to dump it. Is there anything safe that one could cover the nick with? or is it a lost cause.
This is a "what if "![]()
Any cheap meter from walmart, home depot, lowes, radio shack, etc is just fine.

What if? You think the quotes helps? What if instead of you throwing away the battery like you should, you use that battery and it leads to a world changing series of events that spawns the next hyper super virus? What if that battery, when charged, irreversibly knocks out the world wide electrical grid? What if that battery causes some sort of negative butterfly effect causing the next pope to become the next Hitler? What if you visit the Cern Super Collider with that battery and it causes the collider to malfunction, turning the earth a black hole? Are you really willing to risk BILLIONS of lives because you didn't want to spend another $10 on a battery? That's something for you to think about young lady.
If it was me, I'd just hit it with some e-tape and vape away. Armageddon be damned.
