Interesting update

Now it has been about week and 2 days after I got the mini. I replaced my first battery 2 days after.. it was not holding charge and flashed just after few puffs off the charger.. I charged it for 12 hours but it was useless..
After another 5-6 days of usage both batteries failed, one with the pneumatic switch failing and the other like the first one - no charge holding and very weak smoke.
Luckily the e-cig.bg reseller grants 1 year guarantee so they exchange failed batteries without problems.
Today I replaced both batteries, gone to work and put the first on the charger. After about 6 hours I had to go home so I took the charger and the batt out of the wall. I was going to put it on charge at home for some extra hours

.
At this point I noticed that the battery looks strange. It does not have the tiny stripes imitating real cigar, plain white and its not glossy but mat. The original one are little yellowish but this is plain white. It also does not have SLB mark at the bottom as explained
Here.
Are these fake? anyone noticed such batteries?
