Battery properties

There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded when they are exhausted, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers.

Li-ion

A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as the electrode material, compared to the metallic lithium used in non-rechargeable lithium battery.

Voltage

The voltage between two points is a short name for the electrical force that would drive an electric current between those points. Specifically, voltage is equal to energy per unit charge. In the case of static electric fields, the voltage between two points is equal to the electrical potential difference between those points. In the more general case with electric and magnetic fields that vary with time, the terms are no longer synonymous.

Erweiterungs-Akku für extrem verlängerte Betriebsdauer (9Cells, 8850mAh)

Super Zusatzakku.

+ Hat doppelt so viel Kapazit...

Super Zusatzakku.

+ Hat doppelt so viel Kapazität wie der integrierte Akku des HP 8570p (~2h) --> Notebook kann 6h auf höchster Helligkeit betrieben werden, alle Energiesparmechanismen aus!
+ Sehr nützliche LEDs am Akkuboden, die per Knopfdruck den Ladestatus anzeigen
+ Durch die "Verdickung" des Laptops wird die Tastatur angenehm angehoben, ein Desktop-Tastatur-Feeling entsteht
+ Akku kann auch seperat geladen werden, er hat eine normale HP-Strombuchse

- Macht Laptop natürlich dicker, hab aber nix anderes erwartet

Würde sofort nochmals zugreifen!

Super Akkuleistung.

Eines muss ich bemängeln:

Wenn der Akku in Schnapp-Vorrichtung eingeklinkt wird, hat es zwei Schieberegler
links und rechts.

Wenn sie auf Rot stehen sind sie geöffnet und bei schwarz geschlossen.

Also logisch wäre da schon:

Grün: geöffnet
Rot: geschlossen

Des weiteren, wenn man den Laptop dann etwas verschiebt, kann es sein, das der Akku aus der Arretierung heraus fällt. Blöd wenn man einen Parkettboden hat.

Bei der Laptop-Positionierung, immer hoch halten und wieder hinstellen. Es liegt an den Gummistützen des Akku, die auf glatter Oberfäche sehr gut haften.

Trotzdem ein sehr gutes Produkt.

Bitte ein Feedback von anderen Käufern, betreffend Arretierung.
Produkt wurde mit einem HP 8560w, HP 8570w und HP 8770w verwendet.

Dringend auf Kompatiblität achten.
