The Dolgin Engineering TC-400 Charger for Canon C100 / C300 / C500 / XL2 Batteries is a microprocessor-based battery charger that provides fast and safe simultaneous charging of 7.2 battery packs that come with Canon's C100, C300, C500 and XL2 cameras. The charger features an LCD display that indicates charge status and true capacity upon charge completion. True capacity is determined by a built-in Test/Discharge module in the charger. The module cycles a battery through a charge-discharge-charge process to test the battery's capacity.
A 100-240V AC power supply is included.
