Good battery that delivers what it promises

Since the eGo C Battery adjustable and especially unlike battery makers is affordable, I've bought one and am thrilled. The battery lasts incredibly long the wheel turns easily, and the steam behavior is individually adjustable.
Very strong buy recommendation. Have me a second Ordered.
Delivery was quick.

So unfortunately a small supplement. One of the two batteries has now given up the ghost. It depends almost 6 hours a charger, but after 30 min empty. And regardless of whether I use it or not.
Had it unfortunately again return.
