The Futaba CR-2500 is a DC multi charger for the lithium ion LT2F2200 battery used in Futaba radio control transmitters and for nickel cadmium and nickel metal hydride batteries used in receivers and glow boosters. It can charge two batteries simultaneously, such as a transmitter battery with a receiver or glow booster battery, and its LCD shows charging current, input voltage and error messages.
The instruction manual explains the charger controls, charging modes, ratings, input cable connection and charging adapters. It also lists safety precautions, including not leaving charging unattended, stopping if the battery reaches 60°C or becomes abnormally hot, and not using the RX/GLOW terminals for batteries other than nickel cadmium and nickel metal hydride types.
