I've been reading up on Batteries but still am confused.
Can someone tell me which is a stronger better Battery between the following:
Ultrafire TR 18650 5300mAh 3.7v
MXJO IMR 18650 3000mAh 3.7v 35A

Thanks. Another question is 3000mAh better or worse than 5400mAh?

I'll way in by saying with vaping your will be looking for their continuous discharge rating before looking at their Mah rating, we generally suggest batteries in the 20 to 30CDR range, this puts you in the 1500 to 3000mah maximum range, batteries 3500mah and higher are generally only 5 to 10amps CDR range. You have to sacrifice mah (run time/energy density) for current (power capability), so that knocks the 5300mah Ultrafire off the list. Next we go with quality and assurance, that means authentic A Bin Grade batteries from authentic Manufacturers, here in the USA and most of the world that is only 4 manufacturers, Panasonic (Lower End)/Sanyo (Higher End)(Same Company), LG, Samsung, and Sony, other companies like MXJO, Efest, AWT, IMRen, Eizfan, and several others, including AW (Andrew Wong) buy their battery cells from these big 4 manufacturers, we call them re-wrap companies. Re-wrap companies buy some times authentic A Bins (AW IMR (generally Panasonic/Sanyo Cells), Sub-Ohm Cell (Generally LG H2/HE4's) are generally pretty much in this category, MXJO, IMRen, Efest and the others buy up the B and C bin discards pretty cheaply, remember these are cells that didn't pass muster to get an authentic manufacturer label and A Bin wrapper. These re-wrap companies then print on the labels the maximum pulse discharge rating (pulse could be 0.5seconds up to about 3 seconds then the battery shifts down gears to CDR (cruising gear)) which is generally about double what the true CDR of the battery is as the battery's CDR.
Examples you listed -
MXJO IMR 18650 3000mAh 3.7v 35A
LGDBHG218650209G282A5
The MXJO 3000mah @ 35Amps (35 what? PDR or CDR?) (look at this next for a mind twister)
LG LGDBHG2 18650 True Specs (20amp CDR, 35amp PDR, 3000mah) <---Guess what is under the wrapper of that MXJO, a B Bin LG HG2 3000mah 20amp CDR battery that didn't pass muster for LG to put their own name onto the wrapper.
Ending sum of this equation through process of elimination
LG HG2 Chocolate Browns
Sorry for the long reply, but with battery safety I try one vaper to the next to get a vaper to think about their safety, and safety starts at the battery being the battery is the most volatile, buy authentics from the big 4 manufacturers, and buy them from authorized re-sellers/retailers, most re-wrap batteries are double the price of the authentic, so you can get 2 authentics for the price of a single re-wrap.
