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.

Had this battery installed on my HP Pavillion and it works like champ! Easy to install. It was somewhat charged when I received it. Took about 10-15 for fully charged. I haven't charged it since I purchased it about 3 days ago. Durable and perfect size. Absolutely recommendable!

Very inexpensive. But is working great!

I bought this battery for an HP Pavilion 15-ab292nr since the original nine-year-old one stopped accepting a charge. It physically fits into the battery compartment, but it's a little tighter, and it's not a perfect fit like the original battery. It came 80% charged. It holds a charge. I did several charge/discharge cycles, and it charges up to 32,205 mWh. I only get around three hours of mixed-use out of this battery (this laptop has always been a battery hog, so that's normal), but it doesn't matter since I always keep it plugged in when I use it.

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.

Fit perfect. Powered up laptop as intended. Works and performs flawlessly.

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.

My new battery came well packed, and with plenty of instructions for installation and usage. Just installed it to a customer's laptop and it came with a 33% charge that I'm to take to 10% (as per the instructions). Only complain is that the screw holes are like 1 mm or less further than the original battery and I had to put some strength when sliding it in, but it screwed nicely in place after that. Looking forward to seeing this battery work wonderfully for a couple years.

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.

Excelente

Bra pris

En principio no hay nada reprochable. La bateria es perfectamente compatible y su duración es razonable, aunque no puedo indicar exactamente su rendimiento en horas tras una carga completa porque el uso que hago de ese portátil es esporádico.

Rapporto qualità/prezzo superiore a quelle originali che ho acquistato in precedenza sul market place per sostituire quella installata di default sul mio Notebook HP Pavilion dv7-6b41el Entertainment. Arrivata nei tempi stabiliti grazie all'impeccabile servizio di consegna di Amazon, la batteria presentava un'età di 50 giorni mentre quella sostitutiva originale, acquistata in precedenza, ben 270 circa (verificabile tramite la funzionalità "HP support Assistant--->Controllo batteria"del mio laptop). Infatti bisogna considerare che una batteria agli Ioni di Litio (NB: diversamente da quella ai Polimeri di Litio!), pur possedendo potenzialmente infiniti cicli di ricarica, è soggetta a un deterioramento che avviene nel tempo a partire dalla data di produzione, indipendentemente dall'utilizzo (il processo di deterioramento delle celle avviene più velocemente se la batteria viene sottoposta a calore eccessivo da parte dell'utilizzatore finale). Mi impegno ad aggiornare il mio feedback riguardo il livello di usura dell'articolo tra un anno da oggi. Per ora posso consigliare l'acquisto di questo prodotto. Aggiornamento Eccomi a qua a distanza di un anno ad aggiornare la mia esperienza d'uso. Ricordo che ho sempre utilizzato un coolig pad e sono stato attento a non farle soffrire troppo il calore e ho regolarmente effettuato cicli di scarica/carica programmate. Allora, il mio giudizio è eccellente! Ad oggi 09/10/2016, vediamo un po' i dati tramite funzione "Controllo Batteria HP": Età batteria: 409 giorni Temperatura: 24 °C Capacità di progetto 4400 mAh Capacità carica completa: 4137 mAh (94%) Capacità residua: 4137 mAh Voltaggio terminale: 12529 mV Voltaggio di progetto: 11100 mV Voltaggio cella 1: 4169 mV Voltaggio cella 2: 4182 mV Voltaggio cella 3: 4178 mV Voltaggio cella 4: 0 mV Batteria performante e consigliatissima da non farsi sfuggire per il proprio laptop.
