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 Review

Computer worked fine on electricity. Installed battery to computer and it started to boot up then heard a buzz and computer shorted out. Had to buy new computer.

Started failing to fully charge after two months and less than a handful of cycles. Right away disappointing runtime on my laptop. Now the laptop starts blinking the charging light and refuses to charge the battery, unless I apply some tricks and get it to 68% (power off, disconnect from power, remove battery, press power button for 10-15 sec, reconnect to power, start up, reinsert battery).

I only had for 2 months, and so far it’s great. I used it in my 5 year old HP laptop. The new battery seems to be lasting longer without changing it. It was very easy to install and the price was good.

My original laptop battery lasted a long time. Then got to a point where it didn't last for very long before running down. This new replacement is the exact same model. So, I expect it will last as long as the old one. Good transaction, good price.

Our old battery couldn't be off the charger for more than 15 min. This charger brought our laptop back to life! After charging it all the way, we had 14 hrs no problem before needing to plug it in. We probably could have waited longer but we like to charge it over night.

My HP Envy 17 laptop was taking 5 minutes to boot up. It turns out that the 3 year old battery was bad and Windows checks the battery during the boot up process and flashes a very short message on the screen. This battery was an exact fit and has performed very will. Boot up now is only 30 seconds! Oh, and the price was fantastic!

Battery gave out on laptop at the worst time. Went on Walmart, found this item, ordered and back working better then ever.

Fits my computer just like the original and works like a dream. So nice to have my laptop work portably again! Very happy with this purchase.

battry died. bet buy said no wy to replce and i was conned to buying a bran new computer. then geek squad came to house for another reason, and they said just buy it on amazon. so i did, quick fix and another 1500$ computer i didnt need to buy. oy vay

Lasted 6 months. You get what you pay for. Unfortunately, it's impossible to find a genuine battery for sale for such an old laptop.Update: the company contacted me and had me return the battery and offered me a refund or replacement. I opted for the refund and it was just received today. I updated the rating to 3 stars to encourage good customer service habits and for the fact that if you want to explore contacting the company for a faulty product in under a year, it may yield favorable…

My laptop internal battery quit holding a charge. This purchase was the replacement. It has worked quite well and glad I was able to get it quickly. My HP laptop is getting old by today's standards, and parts are hard to find locally.

The battery went to 100% very quickly and is functioning properly so far. It’s too soon to tell how long it will last. Thanks for attention.

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…

Had this for about 2 years and 10 months, worked pretty good for the majority of the time except for when it blew up. So im conflicted in the rating but since it blew up I will have to give it 3 stars (3.5 not available)

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…

Loved the speed of delivery. Battery was difficult to fit in my laptop, but after about 10 minutes of trying, it finally clicked in.

I didn’t expect my laptop to run better but it does. My laptop was too slow to game on with the old battery. Now it works great. I guess the processor was starving for power even though it was plugged in all the time. I’ll always keep good batteries in my laptop from now on. Snapped right in. No issues.

The item arrived on time in a large box. I thought it was too much box for the item. Battery life is kind of questionable on my HP beats laptop. But I think there are only 3 NiCd batteries in it. Other than that it works as advertised.

This was exactly what I was needing. I don't know about battery life or durability as I have had this for only a few weeks. Just ordered this battery have not had it long so can''t say to much but so far works great..

I needed a replacement battery for my olg HP Pavilion laptop. The one provided by TSKYBEAR fit my laptop and was completely charged after being plugged in overnight. Will know how good it works after I take the laptop on my vacation next week.James B.
