 The JK50 Service Pack battery allows replacement of a deteriorated component while maintaining the electrical specifications corresponding to compatible Motorola devices. Its rated capacity of 4850 mAh and typical capacity of 5000 mAh provide a solution for restoring battery life affected by battery ageing. Official part number SB18C77591 facilitates replacement identification and verification against the removed component, particularly when repairing different generations and regional variants. Its application across numerous Motorola models simplifies part number management and inventory maintenance in specialised repair workshops. Its lithium-ion polymer technology and nominal voltage of 3.8 V correspond to the component's characteristics, allowing replacements to be carried out using a correctly identified genuine battery.

- Switch off the device completely before starting and use electrostatic discharge (ESD) protection.

- Reduce the installed battery charge below 25% before disassembly to minimise risks during handling.

- Disconnect the battery before removing it, avoiding punctures, deformation or damage to its casing.

- Check that the JK50 reference and connector match those of the removed battery.

- Position the new battery in its housing and carefully connect the flex cable without forcing the contacts.

- Remove any remaining old adhesive and use suitable fixing adhesive to secure the battery.

- Check device startup, battery recognition, charge percentage and charging system operation before closing the device.

- Perform a calibration cycle when necessary to stabilise the battery percentage reading.

- Replace the rear cover sealing adhesive when applicable and verify that it is correctly secured. Take the removed battery to an authorised recycling facility.

 The Motorola Moto G50 5G XT2149 uses the MS50 battery and must therefore not be confused with the Moto G50 XT2137, which is compatible with the JK50 battery. Always check the device's technical model and original battery reference before replacement.
