NinjaBatt 807956-001 Battery for HP HS04 HS03 807957-001 HSTNN-LB6U

A hp replacement battery was in good condition charges, while charged lost long. Thank you very much.

My machine wouldn't start up and I hoped a new battery would get it going - fortunately it did. The price is reasonable and it looks exactly like the old HP battery. This product seems to work very well and the instructions are certainly clear. Although with the caveat that it is early days yet, I am definitely very pleased with my purchase.

Works in my HP, Seems to hold battery life. My HP doesnt recognise the battery but it works fine. Good value for Money

Fast delivery and the product fit my HP laptop perfectly. I wish the battery life was a bit longer, but hey, it's ok. I recommend this product

Fantastic revived my laptop , good fit easy to install and good battery life

This battery is perfect. Was a great price and great service too, would highly recommend. Thank yoi

Well it does work so there's that. Doesn't work for that long though! A couple of hours from a full charge doesn't seem that good to me tbh maybe three at a push

Although the battery arrived completely flat, it was quick to charge and I was able for the first time in a long long time to work on my laptop for several hours without using the power lead. As per the instructions as soon as it drained to 20% I plugged in the lead removing again once fully charged. very pleased with this battery.

Dopo lunghe ricerche effettate al fine di eseguire la sostituzione di una batteria per il mio Notebook HP Modello 15AY137NL, sono rimasto piacevolmente sorpreso in quanto il modello della batteria acquistato è risultato sin da subito perfettamente compatibile e funzionante. Non appena acceso il computer, la batteria si è presentata con l'80% di carica disponibile, senza riscontrare alcuna anomalia. A valle dell'utilizzo del pc, vedremo durante il tempo come la batteria si comporterà. Prodotto consigliatissimo.

Ich habe meinen alten HP-Laptop wieder flott gemacht, um ihn im Hobbykeller für meine 3D-Druck-Software zu nutzen. Leider war der Originalakku defekt, was ständig zu nervigen Fehlermeldungen führte – und der Laptop lief gefühlt sogar langsamer, obwohl er am Netzteil hing. Der NinjaBatt Akku hat hier echt Abhilfe geschafft: ✔️ Passt perfekt ✔️ Lädt schnell auf ✔️ Hält richtig gut durch Seitdem läuft das Gerät wieder flüssig und störungsfrei. Auch die Preis-Leistung ist top, man merkt sofort die Qualität. Kann den Akku absolut empfehlen – gerade für alle, die einem älteren Gerät noch mal neues Leben einhauchen wollen.

Allow to replace the original HP battery without any problem. After initializing the battery (some charge/discharge, as indicated in the accompanying leaflet) cycles I got 4 to 5 hour of autonomy.

Prima accu voor de laptop, past precies, heeft een lange batterijduur en laat snel op. Snelle en correcte levering.

C’est un produit qui m’a très bien dépanné lorsque la batterie de mon ordinateur a lâché, je n’ai pas eu de problème pour l’installer à la fonctionné directement
