Safety first: Remove the battery before inspecting terminals or PCB.

Check battery fit: Ensure the battery locks firmly into place without movement.
Clean terminals: Wipe battery and vacuum contacts with a dry cloth.
Test with another battery: If flickering disappears with a different battery, replace the original pack.
