The Christie Trickle Charger (CTC)-500 is specifically designed to trickle charge vented Nickel Cadmium and Sealed Lead Acid aircraft batteries. In Constant Current Mode the charger can be configured to the Nickel Cadmium battery manufacturer’s recommended trickle charge rates or switched over to Constant Potential Mode for a Lead Acid battery. A regulated current and undervoltage set-point allows full battery capacity to be maintained while the battery is on the shelf. The CTC-500 has a European line voltage selector switch, which allows the charger to plug into 115VAC or 230VAC input power. This trickle charger is capable of handling the entire range of both Marathon’s Standard Super Power and new Micro Maintenance battery products. The CTC-500 is available through a Christie Authorized Distributor. Complete with a user manual, the CTC-500 begins trickle charging the battery when connected to an AC power outlet. The manual addresses the set-up procedure for different Amp Hour batteries. This procedure can be performed at MarathonNorco Aerospace when ordered.

Christie Trickle chargers can be used to extend the active (charged) storage life of a Nickel Cadmium battery from 90 days to as much as one year. This saves operators money on batteries that time out and have to be serviced prior to being installed on the aircraft. The trickle charger provides a low, precise constant current charge that overcomes the battery’s natural rate of self-discharge. Batteries connected to a Christie Trickle charger can be removed from storage and placed directly into service without any additional charging making it a valuable tool for operators managing their spares pool
