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 Sangmin Barrett

Battery arrived quickly and it works. To potential buyer: Read all of the specs on your original battery before purchasing. I did and knew beforehand that the Amps/Volts/Watts were not exactly the same in at least one category. But I needed a WORKING battery that fits my aging HP Envy 17T exactly and this one does. HP still can "eventually" send me an exact replacement including in power, but good grief an OEM replacement is spendy these days! I gave this one a 5-Star rating mainly on that it came so quickly and that the price is reasonable in this inflationary environment. Battery does run down rather quickly as older 17" full power Windows 10 computers does suck the power away. I've ordered from this supplier before and also had received a battery quickly when speed was important.
