The top of the battery is usually etched with the battery size. Usually only the positive side of the battery is etched. The negative side might not have any markings at all. In some button-style batteries, the positive side is slightly raised. Check the device for a positive symbol.

What is the circuit board on a vape battery?
Batteries have a small circuit board, usually on the bottom of the vape battery, that stops the charging or discharge of the battery in certain circumstances, such as Over-Charge, Over-Discharge and Short-Circuit. These tend to be slightly longer because of the circuitry and are normally classed as ICR.
How many volts does a vape battery have?
They provide nominally 3.7 volts of power, 4.2 volts when fully charged and slowly discharge when used. Once the vape battery is discharged below approx 3 volts, they must be charged again.
Why does my phone battery overheat?
Using a different cable to that which your device came with can damage your battery. This is because the cable may have a higher voltage than your battery which will cause your device to overheat.
What is the difference between a mechanical and regulated mod?
A mechanical mod takes power DIRECTLY from the vape battery, which means it’s important to know that the battery is capable of providing the current required to fire the coil.

What is an unprotected battery?
Unprotected batteries are normally classed as IMR or INR. Both Protected and Unprotected batteries come in either ‘Flat Top’ or ‘Button Top’. This means that the positive electrode (end) of the battery is either Flat or Button, with most mods using the ‘Flat Top’ type.
What does the plus sign on a battery mean?

Kind of a dumb question.... Just started Saturday getting into the rebuild-able atomizers and mech mods. Went into my local vape shop and chatted with them for awhile. Got set up with everything to build and built my first coil that day. It turned out okay, higher ohm than I wanted, which brings me to my actual question.

The center pin is positive and the outer posts are negative. Honestly it doesn't really matter unless you are going for some fancy builds. As long as a coil is hooked up to positive and negative you should be fine. Parallel coils are a little bit trickier as you want to build them at twice the ohm value as your target (for dual coils ).

normally the post that has the insulator at the base of it is the positive post. This is also considering that the battery is inserted + end into the mod so it ends up with the + end of the battery at the top of the mod...

If making dual coils, test each one separately to make sure the have the same resistance (at 2x your target value, as noted above). Don't go by "final", parallel, reading of both.
