The short answer is the more mah you have the longer the battery will last. This explains why we have mods out using the 18650 batter in the 2-3000 mah rang that people vape on for 2 days or so using 1 battery.
The longer answer:
mAh
Milliamp Hours.
A unit for measuring electric power over time. mAh is commonly used to describe the total amount of energy a battery can store at one time.
A higher mAh rating means the (fully-charged) battery can power a device that consumes more power and/or for a longer amount of time before becoming depleted and needing to be re-charged. For example, a battery rated at 1500 mAh can power a device drawing 100 milliamps for 15 hours, or a device drawing 150 milliamps for 10 hours.
As far as dripping, the battery type would not effect it either way, the bigger concern for dripping would be manual battery verses UNSEALED auto battery where juice can get inside the auto switch and short it out etc. This is why manuals are suggested/prefered for dripping. Not to say you cant drip with an auto, more care and risk of short is the drawback however.
Hope this explains it
