Advanced Charging Technology

The Cotek CX2415 is engineered for precision charging, using a sophisticated 3-stage process to maintain battery health:

1. Bulk Charge: Rapidly replenishes charge in depleted batteries.
2. Absorption Charge: Slows charging to ensure full battery capacity is reached without overheating.
3. Float Charge: Maintains a full charge without overcharging, preventing battery damage.

This process helps extend battery life, making it ideal for deep-cycle battery applications.

Universal Compatibility and Safety

With its wide AC input range of 90-264VAC, the CX2415 is suitable for various power environments worldwide. It incorporates Active Power Factor Correction (PFC), improving energy efficiency and reducing power consumption.

The charger includes multiple safety protections:

• Short circuit protection
• Overvoltage protection
• Over-temperature shutdown
• Brown-out protection

These safety features ensure reliable performance and protect both the charger and connected batteries from potential damage.

Smart Fan Control and Thermal Management

The CX2415 features an intelligent cooling system with a 2-stage fan speed control. This minimizes noise and enhances the longevity of internal components by adjusting cooling based on temperature and charging load. The result is a more efficient and durable charging system.

Battery Rescue and Maintenance

A standout feature of the CX2415 is its Battery Rescue Mode, which helps recover over-discharged batteries. This function is particularly useful for restoring performance in batteries that have been sitting idle or deeply discharged due to prolonged storage.

Additionally, the charger offers voltage and temperature compensation when used with the optional battery temperature sensor, ensuring precise charging in different environmental conditions.

Remote Monitoring and Control

For users who require remote access, the CX2415 supports the CR-1 Remote Controller (sold separately). This remote interface allows for real-time monitoring and adjustment of charging parameters, making it convenient for inaccessible or hard-to-reach installations.
