VI04 756743-001 Battery Replacement for HP ProBook 440 G2 450 G2 TPN Q139 Q140 Q141 Q142 Q143 fit for HP Envy 14 15 17 Series Spare 756743-001 756745-001 756479-421 HSTNN-DB6K HSTNN-LB6K

Very easy installation. Works well. Holds charge for a good while.

I was very skeptical in purchasing an off brand battery for my HP Pavilion laptop but have been using my adapter for way too long, I finally took the plunge because my original battery was toast. When I received the battery, I took both the original and this one side by side and it looked identical for the most part. I then went to snap it into place and although the original was a smoother fit, this one clicked in after I aligned it perfectly. For a split second I thought maybe it wasn't going to fit because it was a little tighter than the original. Not tighter like I had to shove it in, just a big more snug. I put it in, then snapped it out to make sure I could do it again, like I wasn't trying to force it in, and it went in again no problem. I've had it for a few weeks and it holds a charge and I am a free woman to use my laptop without the adapter plugged into the wall (although I am still in a habit, haha!). I would highly recommend purchasing this battery if you need one for your laptop. It works, no problems so far. I'm happy with my decision. ***UPDATE *** It has been 4 years since I purchased my battery & it has worked great, holds a charge, no problems so far! (Nov 2, 2022)

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.

Because I was charging my old battery incorrectly, I was looking to replace it with a new one. This product works as expected! Previously, due to my habits, I would need to keep my lap top plugged in at all times, or when I unplugged it, I would need to have it plugged back in within the hour. This battery lasts a couple hours. Hopefully I will follow the correct charging process and not ruin this battery too :(

I was a bit concerned with the fit but it works for my hP pro book 450g2. Initially I didn’t think the battery was holding charge but it turned out the battery was just dead although plugged in it said 64% but overall it works well.

Battery was installed and used in an HP Pavilion 17 laptop in December 2021. At first all seemed to work well. Decent battery life for a good price, but performance has deteriorated quickly to the point where less than 7 months later, unplugging the laptop from the AC adapter results in immediate shutdown of laptop, meaning that the battery was no longer capable of keeping the machine running. Fortunately, I still had the OEM battery on hand and was able to continue using that, albeit with short battery life. A piece of paper enclosed in the packaging listed a 1 year warranty and an email address to contact. When trying to obtain a warranty replacement, I attempted to use this contact information, and the email was bounced back to me as a bad address. I apparently am on my own. Maybe it's a bad unit- that's always a possibility. But be aware that getting the vendor to stand behind their product may be a challenge.

My HP ProBook flashed an error message that said my original battery was going bad. Rather than buy an expensive one from HP or a distributor, I found this one on Amazon for half the price and with good reviews. It arrived promptly, fit perfectly, and charged up just fine. My ProBook didn't like it much. It sent me another message that it detected a non-HP battery. But that has not caused any performance issues so far. I haven't had this one installed long enough to rate its durability or battery life yet. But going on the assumption that it will last at least the five years the original one did.

This is just what my laptop needed. I thought I was going to have to replace it but all it needed was a battery replacement.

The battery arrived promptly, in good condition, and was easy to fit. I haven't had any problems with it so far

Bonne autonomie pour un Pavilion 17

Akku Funktioniert trotz Alter des Laptops einwandfrei

En principio funciona correctamente. Todavía no la he calibrado que es algo que hay que hacer para que los ciclos de carga se optimicen

J'ai acheté cette batterie pour redonner vie à un ordinateur portable assez ancien, et c'est un succès. La batterie tient une journée, le fait qu'elle soit plus grosse fait qu'elle surélève l'ordinateur, très pratique sur un bureau. L'installation s'est faite en moins de 5 minutes sur mon Latitude E5530. Je recommande !
