Having to charge it more frequently (i.e. due to it giving you less vaping time) also means there will be extra wear and tear caused on the battery. The price gap between the Samsung 25R and the Molicel P26A with the former being currently on sale is still only $1.41 so 41% more expensive, BUT... at 10A continuous discharge down to 3.2V (i.e. vaping at only ~60 watts on a dual battery regulated mod), the former only delivers about 7.2Wh versus 7.8Wh for the latter (versus 7.53Wh for the Samsung 30Q) so, at that kind of wattage, this equates to the P26A being only ~33% more expensive─not 41% more expensive─in the long run. Granted, in the example I gave, this difference is still more than a buck per battery, but you will be enjoying that little bit of extra vaping time for a very, VERY long time to come, and, the higher you go above 60 watts on a dual battery regulated mod, the poorer the decision of going for the 25R will become. So, even if you run them at much less than 100 watts per pair, skimping on your batteries in this manner is not actually worth the trouble of changing out the batteries more frequently causing extra wear on the battery door and contacts of the mod. That is, excepting only maybe if a one buck difference per battery forces you to eat Top Ramen for a week. (Which, hopefully, you don't have to.)
