HP Pavilion DV6 for my. The battery holds only 40 min max. She discharge excruciating speed! After 2 minutes of use charged at 100%, the battery passes 92% not even 2 min then 86% ... Very frankly, I forbid customers to buy this battery. This is crap. I am disappointed even upset. How can we sell the same product. ESPECIALLY NOT BUY !!!!!!!!!!!!!!!
