  • Ariel Switzerland

    Battery works very well. What I have noticed, however: If the laptop is already old, even a new battery will not deliver the same runtime as a new laptop. Even though my Elitebook 830 G3 runs longer, it still lasts less than it did at the very beginning. I don't know why, but that's how it is. Still a worthwhile purchase

  • Oliver Germany

    Fits, wobbles and works :-) Battery was shipped well packaged and after a good 3 weeks of use, its performance has been confirmed. HP laptop uses the battery capacity to below 10% or lower and then shuts down properly. Battery performance lasted 3-4 hours and remained stable until the end. With other inexpensive purchases, the laptop suddenly turned off at 30-40% of the time. As of today - absolutely recommended! Nice greetings from Hamburg

    Battery for HP EliteBook 850 G3 - 3100mAh 11.4V, HP CS03XL: Everything was great from ordering to delivery. The battery fits wonderfully and works well. I can't give any information about the durability after 2 days of use. Note: There are no mounting screws included with the battery supplied. This means that after removing the old battery from the notebook, you have to unscrew the 2 fastening screws attached to the old battery and attach them to the new battery before installing the new battery. ATTENTION when unscrewing the two small screws from the old battery!!! The 2 screws are firmly connected to the old battery using springs and small (approx. 2 mm diameter) washers. The two springs and the two washers can easily be lost during removal. The 2 screws, the 2 springs and the 2 small washers are needed to attach the new battery to the housing.

    Product perfectly compatible with an HP850 G3 laptop, as indicated in other comments the battery is not delivered with the 2 fixing screws but it is not a problem, Processing of the order and fast delivery

  • Didier France

    Product as ordered and delivered very quickly. Once installed as a replacement for old batteries, the affected PCs are like new. I recommend Subtel.

  • Martin Germany

    very fast delivery, cheap — and: finally a non-original battery that has a very good capacity. I'm completely satisfied.

  • Santeri Finland

    Every product I've bought from Subtel has worked perfectly so far and the price-quality ratio is good.

Description

CELLONIC replacement battery for laptops and notebooks

A worn laptop battery can limit time away from a power socket when you work, stream or play games. Compare the exact laptop model, battery reference and connection before replacement, and follow the manufacturer’s instructions. Unexpected shutdowns can have other causes, so a new battery should not be assumed to fix every fault.

    Batterie funktioniert sehr solide. Was ich jedoch bemerkt habe: Wenn der Laptop schon alt ist, wird auch eine neue Batterie nicht die gleiche Laufzeit liefern wie ein neuer Laptop. Auch wenn mein Elitebook 830 G3 wiede rbedeitend länger läuft, hält er immer noch kürzer wie ganz am Anfang. Ich weiss nicht warum, aber so ist es. Trotzdem ein lohnender Kauf

    Passt, wackelt und funktioniert:-)
    Akku wurde gut verpackt versendet und nach nun gut 3 Wochen Benutzung hat sich seinen leistungsfähig bestätigt. HP Laptop verbraucht die Akkukapazität bis unter 10% und tiefer und fährt dann ordnungsgemäß runter. Akkuleistung hat 3-4h gehalten und bleibt bis zum Schluss stabil. Bei anderen kostengünstigen Käufen war auch schon mal bei 30-40% der Laptop plötzlich aus.
    Stand heute - absolut empfehlenswert!
    Schönes Gruß aus Hamburg

    Akku für HP EliteBook 850 G3 - 3100mAh 11.4V, HP CS03XL:
    Von der Bestellung bis zur Zustellung war alles bestens. Der Akku passt wunderbar und funktioniert auch gut. Über die Haltbarkeit kann ich nach 2 Tagen Verwendung noch keine Auskunft geben. Anmerkung: Beim gelieferten Akku sind keine Befestigungsschrauben dabei. Das heißt, nach dem Ausbau des alten Akkus aus dem Notebook, muß man die 2 am alten Akku angebrachten Befestigungsschrauben abschrauben und vor dem Einbau des neuen Akkus am neuen Akku anbringen. A C H T U N G beim Abschrauben der beiden kleinen Schrauben vom alten Akku!!! Die 2 Schrauben sind nämlich mittels Federn und kleinen (ca. 2 mm Durchmesser) Scheiben fix mit dem alten Akku verbunden. Die beiden Federn und die beiden Scheiben können beim Ausbau leicht verloren gehen. Die 2 Schrauben, die 2 Federn und die 2 kleinen Scheiben benötigt man für die Befestigung des neuen Akkus am Gehäuse.
