Review on 12 Months Warranty HP ProBook 440 G2 450 G2 TPN Q139-Q143 Battery Replacement - VI04 756743-001, 756745-001, 756479-421 HSTNN-DB6K HSTNN-LB6K by Patrick Cooney

Updated December, 2018. As of 2 weeks ago (December) my laptop is saying the battery life is gone and I must replace it, and it barely boots up. Even though this battery claimed to come with a 12 month warranty, my ability to return it ended 30 days after purchase and Support closed for is 90 days after I bought it. Do yourself a favor and don't trust this seller. Giving 2 stars because it initially worked. But it just delayed the inevitable; no ability to use laptop.Original Review from June, 2018: So happy this battery fit perfectly and no weird error messages from my beats Audi HP laptop about incompatibility. The laptop didn't register a response to the change so the new battery install was seamless and all is well after having it for the past 5 days.
