Verify part number and clearance

Before ordering, match the original battery part number on your device to the list above and confirm the 4.50 mm thickness fits your chassis. Ensure the connector orientation aligns with the motherboard header and that the screw holes correspond to the mounting points. Buyers who need a higher capacity pack or a different voltage cannot use this unit.

Sustained discharge behaviour

The 5050 mAh cell maintains a steady 7.72 V output during continuous workloads rather than spiking in short bursts. Internal resistance stays stable across the discharge curve, so run-time scales predictably with load. Thermal rise remains modest under constant current draw because the slim 4.50 mm profile spreads heat across the full 249.62 mm length.
