The Lifeboat Battery Charger is a charging device designed for marine lifeboat backup batteries, and its core function is to ensure that the lifeboat battery is in an instantly usable state. The main functions and technical features are as follows:
1. Core charging control function
Automatic Charging Mode Switching :
Automatically start charging when it detects that the battery voltage is lower than the set value (e.g., 13.3V), and automatically switch to floating charging mode when the voltage rises to a full charge threshold (e.g., 14.4V or 14.5V) to avoid overcharging.
Three-color indicator status feedback:
Red light: fault alarm (such as reverse battery connection, open circuit or short circuit);
Yellow light: charging (constant current/constant voltage main charging stage);
Green light: Full charge.
2. Key performance parameters
Parameter Type Typical Values Description Input voltage AC 24V / 42V adapts to the ship's power system environment
Output voltage DC 12V / 14.5V to match lead-acid or backup battery requirements
Output current DC 5A (single or dual) supports fast power replenishment
IP67 protection is completely dustproof and transient water immersion
3. Safety and adaptive design
Multi-channel independent output: Some models (such as CD-4212-2) support dual 12V/5A outputs, which can charge two sets of batteries at the same time;
Fault protection mechanism: built-in reverse connection protection, short circuit protection and open circuit detection, cut off the output and trigger a red light alarm when abnormal;
Maintenance-specific design: Dedicated to lifeboat regular maintenance scenarios, ensuring the reliability of the battery in emergency situations.
These chargers have passed strict marine environmental adaptability certifications (such as IP67), combined with intelligent charge and discharge management, to ensure the stable operation of life-saving equipment under extreme conditions
