NinjaBatt Battery for HP P106 710416-001 Envy 710417-001 PI06 HSTNN-LB4N M7-J020DX 17-E020US M6-N012DX HSTNN-UB4N HSTNN-LB40 TPN-L112 M6-N010DX 17T-J100 – High Performance [6 cell/4400mAh/10.8v]

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

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

It is great I know my laptop is getting old but its been a great one the New battery works great 👍

The product fits my older HP laptop and seems to be a good battery. I started getting the message that my old battery was no longer holding a charge so I purchased this battery as a replacement. It does fit properly and works well. I do feel the battery life is not as long as my older aftermarket battery but it does the job. Once charged and my computer laptop while on stand by it holds the charge for about a day. When using the laptop, it drains in a few hours. My old battery seemed to last much longer on both stand by and while in use. Hopefully this will will last several years like my old aftermarket one did. Overall I'll give it a 3-4 star battery.

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.

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.

Great product and great service

Arrive on time and fit perfectly. Works like a dream.
