When reduced battery life results from battery ageing, replacing it allows energy storage capacity to be restored without working on other modules that are functioning correctly. For a technical service centre, having an identified reference also facilitates parts management, installation and subsequent charging checks.

• Completely power off the device, disconnect the battery and use electrostatic discharge (ESD) protection.

• Carefully remove the rear cover and extract the deteriorated battery using appropriate disassembly tools.

• Clean away the previous adhesive residue and properly prepare the battery compartment.

• Check the BLPC85 reference and correctly align the power connector without forcing the contacts or flex cable.

• Install the new battery using suitable mounting adhesives and ensure correct positioning inside the device.

• Check device startup, battery recognition and charging system operation before final closure.

• Perform a charging test and verify the stability of the battery percentage during operation.

• Renew the closure adhesives and check correct assembly and sealing of the rear cover.
