The old battery was a little hard to get out, but once out this one just fit right in. Charged it up and laptop is working great. Tip look for screws under the rubber strips on the bottom. They pull up and screws are under them.

I don’t write reviews often, but this laptop battery deserves some recognition. From the moment I installed it, my laptop instantly felt like it had a second wind. The installation was seamless—no tech background needed. It charged quickly, held the power beautifully, and I could immediately feel the difference in performance. As someone who relies on her laptop daily for both creative flow and client work, having dependable battery life is non-negotiable. This gave me peace of mind and hours of uninterrupted productivity. It also came well-packaged with clear instructions and even felt more solid than the original battery. I’m genuinely impressed by the quality. If you're on the fence, consider this your sign—NinjaBatt delivered. Highly recommend.

I ordered this battery about eighteen months ago. I was skeptical weather or not a battery at this price point would do the trick on a six year old HP laptop that was probably at the end of its useful life. The only thing is, I like to get that last little bit out of things if I can. This laptop seemed to be working fine, except the battery just would not charge. It needed to be plugged in 24/7 in order to function and stay updated. I’ve never considered taking a laptop apart to replace the battery. I assumed it was beyond my skill set. But alas, after a quick utube search, I watched a couple minute how to video and felt confident. It looked pretty easy. And besides, worst case, I would have to get a new laptop if a new battery didn’t solve the problem. Win win. The battery came well packaged. It was very easy to install with the help of the utube how to video, but most people probably won’t even need the tutorial. It’s pretty straightforward. The good news is the battery solved the problem and I can now work on my laptop untethered for hours.

Seems like a quality battery. Installed and will now see how it does. So far so good. Only problem was that it took two more days to ship than advertised and I needed it quickly. So only 4 stars.

Worked perfectly and at a great price. 28 days later still working like a charm. Recommend.

Unfortunately this battery died after 4 months, Reaching out to Customer Service at NinjaBatt, my problem was resolved very fast and a replacement was sent overnight. Great service from the two reps I dealt with. Unfortunately there is a problem with something you might buy from time to time. Jolly and Jane took ownership of my problem in a very efficient manner. I thank them for great Customer Service.

Replaced the battery on my HP Pavilion laptop. My touchpad and buttons stopped working and at first, I thought the touchpad was the issue. I saw a video online that mentioned to look at the bottom of the laptop and verify it wasn't swollen. This would indicate the battery was defective and was pressing up on the touchpad preventing it from moving and flexing correctly. Sure enough, it was swollen (see pic). I had never noticed it before because I use this laptop as a desktop and have it set up as such and never move it. Replacing the battery was simpler than I thought (after watching a few YouTube videos of course). This battery was an exact replacement. No issues with fitment or powering on after installation. Says it's a higher rated battery. We shall see. Overall, just happy I was able to fix my computer and not have to replace it.

So far this battery is perfect. The hardest part of the installation was opening up my laptop. Once you get in, there are about 5 screws to remove and the battery slides right out, installation in the same in reverse. I gave it a full charge before using the laptop. The original battery wouldn't even accept a charge, so everything was dead. It initially took quite some time for the computer to boot up. Now it functions as it's supposed to, I've used it a lot since replacing the battery and I still have 86% power remaining. It holds it's charge well and all the mounting holes lined up as they should. FYI...the laptop went back together faster than opening it.

Batteria compatibile per i modelli scritti della descrizione del venditore, quindi mi raccomando controllate bene il codice della vostra batteria così da sostituirla con il modello giusto. La sto usando già da qualche settimana e devo dire che è un prodotto molto valido, premetto di aver già acquistato batterie di questo marchio e mi ci sono trovato bene quindi sono andato sul sicuro. Rispetta tutte le aspettative al momento, se durerà anni come l'originale non lo so ma lo spero perché promette molto bene. La consiglio!!!

Buena marca, buena calidad. La duración de la batería es buena. Tras ya casi un año de uso desde la compra, la batería todavía funciona correctamente.

Article conforme. Livré dans le délai dans la boîte aux lettres. Livré avec instructions. Aucune difficulté pour remplacer l'ancienne batterie. Se recharge de suite. Difficile d'évaluer sa longévité vu que je viens de la recevoir. Pour le moment je suis contente de cet achat.

As always, delivery was fast and wished I’d bought it sooner to be honest! Well packaged, easy to replace and has given my laptop a new lease of life, so a good purchase, very pleased.
