There's a trade off between capacity (mAh) and Amps draw (CDR). More of one = less of the other. Basically you need to know that a battery can withstand the maximum Amps draw you're going to impose on it. Only then should you pay any attention to the mAh, all that tells you is how often you're going to need to recharge it.Sorry if it's been asked before but I can't seem to find an answer. 2500, 3000 or 3400 mAh for vaping. I'm using them in a Aegis Legend at a relatively low wattage (sub 80 usually).
What's the best size for longevity and total life?
