This is the battery that saved my laptop (T430 Lenovo)! The info with the battery was clear (I don't buy many laptop batteries and have no experience with them) and I knew immediately what I needed. Result: old one out, and the new one - click - in after super fast delivery. Neatly fully charged (necessary) and done. Thank you Subtel!

No branded battery, but it is recognized by the laptop, but no capacity, but can be read with the operating system, as a 2-year guarantee is unrestricted recommendation

The product fits and the first performance results are very satisfactory. How the quality will show up in the longer term remains to be seen.
Ekkehard Germany

The battery makes a good impression, is a perfect fit and is an inexpensive offer. I cannot provide any information about the service life at the moment.

Christian Germany

Partly preloaded, ready to use. Price / performance is right. Was recommended by my colleague and was not disappointed, I will gladly use it again. Many Thanks.

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.

Dit is de batterij die m'n laptop (T430 Lenovo) gered heeft! De info bij de batterij was duidelijk (ik koop niet zo veel laptopbatterijen en heb er geen ervaring mee) en ik wist meteen wat ik nodig had. Resultaat: oude er uit, en de nieuwe - klik - er in na super snelle levering. Netjes volledig geladen (noodzakelijk) en klaar. Dank je Subtel!
