Plantronics spare battery charging cable for CS540-XD, CS545-XD, W440 and Savi W740. This item includes the charging cord to USB, the AC power adapter and 1 hot-swappable battery. IMPORTANT: This charger is only made to work with the CS500-XD models listed above and the Savi W440 and W740 or W745. It will not work with the standard CS540 wireless headset as that model uses an internal battery, not the hot-swappable battery.
