At first I was relatively happy, the run time was 5 hours. The thickness of the battery did not bother me, on the contrary, it makes for a better ventilation. However, a battery indicator was not possible from the outset, that you had at any time expect that the laptop runs out, even with a charge indicator of 80% or more.
Now after only 7 months (!) - The original battery provided by HP held at least 2 years and had only half the capacity - is the "Premium" battery of PELTEC broken, or he simply invites not to be, so that it about 5 seconds holds until emanating laptop.
I contacted the seller by mail, but has not received any response or even no one achieved under the given phone number. I'm waiting now to spare.
