How Can I Tell How Many Volts My Battery Is?

[sistercreepy]

I have two or three regular cigarette looking batteries that I use on occasion. How can I tell how many volts these are?

You can tell how much power you get from a battery by testing it with a "Multimeter".

I don't have any but it should say in the specifications or instruction manual or you could google them and see if you can find the voltage that way.

The kr808 bats (blue ecigs, V2, etc.) are typically only 3.7V

You need a multimeter or a screw on voltmeter made for pv's. Multimeter are sold at almost any hardware or electronics store for about $10 or $15. I got the screw on type from madvapes but don't know if they still carry them.

Excuse myself, but those "cig-a-likes" with the pre-filled replaceable cartridges that look like a regular filter on a normal cigarette are what you have, yes? If so, fully charged they are 3.7V's. After using them for a bit (10 drags on mine), the voltage drops off. That's why i bought a VV mod after a month of experimenting with those kr-808's.

Thanks everyone for your response!!

You can find a multimeter from Home Depot or Lowes. They're relatively cheap and they're accurate.

Hold on, there is more variation that just 3.7. This does not come even close, I had to do a lot of digging but this is not quite right. There is also more to it than coming off a charger at 4.2v and running down to 3.3. There is more than regulated at 3.7v. There is more than regulated at 3.2v. These are not the only three.

You will have to measure to be sure buy you will also want to measure over various points in the discharge curve.

You could also get the batteries fully charged and bring them to radio schack and they'll check the voltage for you and you'll save a few bucks on buying a multi meter unless you really have another use for it.

You are not going to be able to tell if it is regulated or know the discharge curve like that.

Now that I think about it there may just one small detail I have overlooked. How do you make the connection to battery in an auto PV? Hard to puff on with a probe sticking inside.
