The W71000A also has a built in charger for easy, overnight charging of the long-lasting rechargeable nickel Cadmium batteries. As an accessory, the converter ring is available in the W71000C handle, which enables insertion of off-the-shelf C-cell batteries in place of the rechargeable batteries for continued operation without the need to wait for recharging.
The W71670 recharges in the Welch Allyn desk charger and numerous stand consoles and well-chargers.
