Reliable and Efficient Charging for Various Applications

The Cotek CX2425 is designed to provide a consistent and intelligent charging solution for different types of batteries, ensuring their optimal performance and longevity. The 3-stage charging process (Bulk, Absorption, and Float) is key to maintaining battery health:

1. Bulk Charge: Provides a constant high current until the battery reaches the target voltage.
2. Absorption Charge: Holds the voltage at a fixed level while the current gradually decreases, ensuring the battery is fully charged.
3. Float Charge: Maintains the battery at full charge without overcharging, preserving battery life.

This process maximizes battery efficiency, ensuring that it delivers peak performance while preventing damage from improper charging.

Advanced Protection and Battery Rescue Function

Battery safety and longevity are critical concerns, and the CX2425 is equipped with multiple protection mechanisms, including:

• Short Circuit Protection – Prevents damage in case of accidental wiring issues.
• Over Voltage Protection – Ensures batteries do not receive excessive voltage, preventing overcharging.
• Over Temperature Protection – Prevents overheating, which can damage both the charger and batteries.
• Brown-out Protection – Protects against low voltage conditions that can affect charging efficiency.

Additionally, the built-in battery rescue function is a crucial feature that helps recover over-discharged batteries. By reducing the initial charge current, the charger can gradually bring a deeply depleted battery back to a safe and usable condition, extending its lifespan.
