📝 Product Description
This replacement battery, with main reference 851477-421, is the ideal solution to restore the autonomy of your HP laptop. Specifically designed to be compatible with a wide range of HP ProBook series models, this 4000 mAh, 11.4V battery offers reliable and safe performance thanks to its Lithium Polymer (Li-Polymer) cells and integrated protection systems against overvoltage and undervoltage.
Each unit is rigorously verified by our technical service to ensure maximum quality and compatibility, providing a direct replacement for original part numbers such as RR03XL, HSTNN-LB7I, and others. Its black color and design fit perfectly with the device's chassis. It is a new component, ready to be installed and restore mobility to your device.
To maximize the lifespan of your new battery, it is recommended to perform an initial full charge and discharge cycle (charge to 100% and use until the device indicates low battery). Avoid exposure to extreme temperatures and do not leave the battery completely discharged for prolonged periods. Calibrating the battery every 2-3 months helps maintain the accuracy of the operating system's charge indicator.
