🛡️ Safety Features
Built-in protections that make this charger safe to use every day
Full-Charge Detection & Cut-Off
Charger stops automatically when battery reaches 14.6V — fully charged. No overcharging. Safe to leave connected overnight.
Reverse Polarity Protection
Connect clips wrong and nothing happens. No sparks, no damage to charger or battery.
Short Circuit Protection
Internal circuit breaker trips instantly if a short is detected. Charger and battery stay safe.
Overvoltage Protection
Cuts power if output voltage exceeds safe limits. Protects battery cells from damage.
Overtemperature Protection
SMPS design runs cool. If the charger overheats, it shuts down automatically. Reduces current if battery heat builds up, preventing swelling or damage.
