Why Choose the Cotek CX1225?

Advanced 3-Stage Charging for Maximum Battery Life

The CX1225 employs a three-stage charging process (IUOU), ensuring your batteries receive the optimal amount of charge at every step:

• Bulk Charge: Delivers a constant current until the battery reaches its designated voltage.
• Absorption Stage: Holds the voltage steady, allowing the battery to absorb energy fully.
• Float Stage: Maintains a safe trickle charge, preventing overcharging and ensuring long-term battery health.

This process is ideal for deep-cycle batteries, as it maximizes performance while preventing overheating and sulfation.

Battery Rescue Mode – Restore Over-Discharged Batteries

One of the standout features of the Cotek CX1225 is its Battery Rescue Mode. If a battery has been deeply discharged, this function gradually ramps up the charging current, allowing the battery to recover without damage. This is especially useful for:

• Solar power systems
• Recreational vehicles (RVs) and marine batteries
• Backup power and off-grid applications
• Industrial and telecom battery banks

This feature helps extend battery life, reducing the need for expensive replacements.
