same CDR, capacity and brand yeah, I wouldn’t be sticking a 30Q with a P26A for instance
ideally it’s best to marry batteries as you know they have been charged together throughout, have degraded at similar rates over time...so they output roughly the same and take similar charges...otherwise your mod will be pushing one harder than the other.
.... but if you haven’t married cells try not to stick an old battery with a brand new one from same company as good practice at the least.
really they are inexpensive compared to what your likely prepared to outlay for attys and mods ....so no reason to skimp on buying a couple new ones and they’ll last you a few years at least

Batteries are cheap, pocket change a month can buy a pair (or at least the amount of change I amass 
)
Now it’s suggested not to mix differing CDR/capacity batteries...
But truth is, if you know watts law and know for a fact you will be using the pair below the CDR of the two... you will be perfectly fine... minus the regulated mod telling you a tad early that a battery is depleted.
Example:
A). VTC5Ax2 = same and preferred method
B). VTC5A+30Q (2600-25a+3000+20A) if you use it at or below the 20A per loaded battery it will work fine. These are differing and not the preferred method.
C). 18650+21700 just don’t
Battery count / wattage = wattage drain per battery
Wattage drain / 3.2v = preliminary Amp draw per battery
PAD / mods efficiency = actual AMp draw per battery
So!
Let’s say you vape at 75w
75/2= 37.5w
37.5/3.2= 11.72a
11.72/.85%= 13.78a draw per battery
13.78a draw is both below the VTC5A and or the 30Q
Mod efficiency I just tabbed in .85% some are higher like DNA250’s at 97%

it's an arranged marriage thing.
shotgun wedding
i marry like don and kingpin say. same brand, kind, age, etc. but i have no problem using just one of them when needed.
I feel myself obligated to point out that this may not be the case for everybody.Batteries are cheap, pocket change a month can buy a pair. (or at least the amount of change I amass)
Yeah I save pocket change but then when I git a bit collected the wife comes by with a baby bottle and wants it filled with change for an expectant mothers thing for church or somesuch... I think she keeps an eye on my stash...

yeah plus that approach won’t take into account internal battery resistance differences ...I just wouldn’t mix and match brands/types personally ...risk reduction and all that
Edit: that mooch video above is ideal watching anyone not logged in who happens across this thread as to the why’s
Is that Pez dispensers on top?
It's a pair of 18650s with smileys I put on em. .
