We have Pink...
Allazar.....the probably reason your getting better vapor with the Holiday battery....(that IS what I sent isn't it?....the Blue one?) is that it's new. Especially these little tiny 4081's.....simply because they are small.....but all lithium batteries eventually wear out. Unless they actually get broken, (dropped on concrete etc) the process is fairly slow.....so what happens is over time with all other variables being the same, (PG/VG content of
juice,type of cartos etc) there will be less and less voltage supplied and eventually they will stop holding a charge all together. Bigger the battery the longer it should last...so like everything...it's a trade off...you want something small and realistic....it wears out faster.
The good news is that IF you actually buy cartomizers from SmokeStik.....battery replacements are free.
