Setup, Compatibility & Care
To ensure peak performance, always connect the charger to the battery terminals first before plugging the device into an AC power outlet. Ensure the battery voltage is correctly identified as 12V; attempting to connect this to a 24V system can cause damage to both the charger and the battery. Keep the ventilation ports on the charger housing clear of debris to prevent overheating. When not in use, store the unit in a dry, cool environment, and inspect the charging cables periodically for any signs of insulation wear or fraying.
