There are two main types of battery in vaping
The physical size of a seperate (external) cell battery is determined by the number ie 18650 or 21700 which indicates 18mm in diameter and 650mm tall etc
How long a battery will last is based off of the mAh which is an abbreviation for milliampere hour. mAh is calculated by multiplying the amount of time the battery lasts by the amperes of the discharge current so essentially the higher the number of mah the longer it will last.
In more simpler terms this will depend on what you want to do with the battery. Most mouth to lung vapers will get through a working day with 1200 mAh up to 2000 mAh for the heaviest of users.
A direct to lung vaper would need 3000mah at least to do the same, as direct to lung vaping is more taxing on the batteries resources.
The reason why a direct to lung or sub ohm vaper needs more mAh is that their coil runs at a higher discharge current therefore using the charge quicker.
