NinjaBatt Battery for HP 695192-001 VK04 15-B142DX 14-B109WM HSTNN-YB4D 15-B129WM 694864-851 14-C050NR 15-B119WM 14-B120DX 15-B123CL 14-B015DX 14-B019US High Performance [4 Cells/2200mAh/32Wh]

So i tried to buy some used oem batteries from the strore for my hp laptop and had to return both of them, i guess all oem hp batteries are too old, and also another extended battery i got lasted only a year until it got swollen for no reason and charged only to 75 percent. I was going to get rid of the 8440p laptop since It was old but wanted to give it one more try. This battery charged to 100 percent and lasted very long. It is the best aftermarket HP battery that can be bough. 5 stars for now, if anything changed within a year i will update my review.

Worked as expected. No complaints. Good value. Arrived on time.

Excellent quality, fast shipping! brought life back to my old laptop and the battery lasts for hours. longer than when OEM was new!

I first ordered two of these batteries in May 2020 (for $30 each) and though I cannot comment on the battery life as I barely leave my laptop running on battery, for the handful of times I have it has lasted for about three hours through casual use (simultaneous web browsing, word processing, calculating and other RAM-light applications), which is more than enough for my needs. It is also difficult to comment on the charge rate as an adapter is near-constantly plugged in, but the few times it has charged from single-digit percentages have been more than satisfactorily fast. Also the packaging is easy to open and the battery popped into my laptop in a snap with absolutely zero problems. I do not know how long the one battery will last but luckily I still have the spare just in case; if you need a battery in a pinch and have a compatible device, this one should serve you well! I give the “NinjaBatt Laptop Battery 484170-001 HSTNN-LB72 for HP Pavilion DV4 G71-340US G60-235DX G60-535DX DV4-2145DX DV5-1235DX DV4-2045DX G60-445DX DV5-1002NR DV6-1030US G70 Presario CQ60 CQ61 [6 Cells/48Wh]” a respectable 4/5 stars!

I have had this for a almost a year. It is larger than the replacement because the laptop sits higher on the bottom from it but I think that is because it is for more battery power, which this unit has. Seems to hold power for long periods and holds a charge well. This is the 2nd battery that I have owned from Ninja. The first one lasted 3 years. I thought I had a problem with this new battery because it would not charge anymore after 10 months and they offered to replace it free of charge within the 1st year under warranty. They were responsive and prompt in replying to me. After emailing them I discovered that the problem was the way the battery was clipped in. Somehow on my laptop a removable panel had shifted which did not allow the battery to make full contact with the charging pins. It clipped in, but on closer inspection the panels to the battery looked off. In fact I had to remove the panel to get the battery out at all. After I removed that panel with 4 screws and fit it back to where it belonged the battery clips in correctly now and charges fully at 100% . It works like new again. My fault completely for not seeing this before contacting them.

Works as expected

Works well when new. 1 year warranty. Completely dead after less than 2 years. No charge held at all anymore. Definitely not the quality of the original HP cells. You get what you pay for I guess.

The battery on my HP Pavilion finally died requiring its replacement. I chose the Ninja battery based on it many positive reviews and have not been disappointed. I did read the one and two star reviews as I always do so was prepared should there be issues. The battery fit perfectly, and I followed the initial charging program as closely as possible. Everything is flawless so far, but I can't attest to life expectancy yet. One caveat: because the battery is not OEM the computer does not recognize it as being installed. That doesn't affect its operation or condition display at all though. I am very happy with this purchase. I feel it is a very good value
