NinjaBatt Battery for HP VK04 695192-001 15-B142DX 14-B109WM 15-B129WM

My laptop had an old battery (?10 years old) that only lasted around 30 minutes after unplugging it. This Ninja battery fitted perfectly and it works. So now I can use the Laptop for a few hrs without having to plug it. It's not recommended to use it until it runs out of charge, but only down to around 20% and then re-charge it. That will extend the life of the battery. You also need to avoid heat and avoid using the Laptop over a pillow or bedspread/blankets since it blocks the air cooling mechanism of the Laptop. The price was reasonable. Very easy to install.

I ordered this battery 4 years ago and been using it with my laptop on daily basses. Maybe I shouldn't keep the laptop still plugged in with the battery on to prolong its life, but I do ... At this point, the battery by itself without watching videos and not being plugged in, can run the laptop for almost 2 hours.

Battery arrived, out of the box fully charged, inserted in to a HP Sleekbook, and works perfect. Battery registers in Windows and works better then the original. I bought one off these style knock offs online before and was DOA. Do not be fooled buy the cheap replicas. This is the perfect replacement, dont hesitate to buy.

My dad needed a battery for his laptop since the one he had was running out of battery life and the charge only a few hours. This was a great lifesaver. I can't say a lot because I did not see him actually install it, but because he learned how to properly place it in the laptop from a computer technician, my dad mentions the install was simple. So far he has had no complaints and he's had the battery for a few days.

Put this battery in an older HP Pavilion and the machine started from just the battery power but would NOT charge. I tried to restart in safemode but had no success there. Got into the system configuration menu (tapping F something on startup, I forget which) and toggled to the BIOS or boot order. I changed it to 'legacy status' and suddenly the machine would boot back up to windows AND the battery was charging. I can't speak to it's longevity yet, but thought maybe this tip would help people who say it won't charge up in their machines.

Original battery lasted 8 years. Then wouldn't stay charged. This replacement battery works great!!

It is very easy to install, virtually identical to the original one. However, it will cause the laptop to short out. The laptop will suddenly turn off completely and pressing the power button will not work. I have to take the battery out, press and hold the power button to discharge the laptop then put the battery in and the laptop powers on. The clips that get inserted into the laptop also broke off almost immediately. The laptop will be ball to be used on low brightness and medium internet or desktop functions (Microsoft word) for a few hours or so, which is still not that great but better then the battery before (came with the laptop when originally purchased) which would drain down after 30-45 mins. It is possible it could be an issue with the laptop but I never had "shorting" out issues when I had the other battery.

I got this replacement battery for my son's laptop. It came quick, was easy to install, but the battery life doesn't last very long. Since my son is still in virtual class, we charged it up the night before. A little less than two hours into class (off the charger), the battery was already under 40%. If you only need to work a short amount of time without a charger, then it's great.

La batterie semble totalement conforme à la description. Elle s'est parfaitement adaptée à mon PC et lui a redonné une seconde vie. Merci aux vendeurs. Je redonnerai des nouvelles de l'évolution du produit dans quelques temps.

Good battery life, about 3 hours of life after full charge. Using the laptop for car coding and music same time. Good value for money.

Ottimo prodotto, imballato perfettamente e funzionante. Soddisfatto di averlo acquistato, lo consiglio.

So easy. Just replaced the battery and I’m back in business with my computer. Very happy with the product so far. It’s been about a month. Still happy with it abs it’s been over 3.5 years
