The numbers on a battery charger typically indicate the charger's output voltage and current, which are crucial for matching the charger's specifications to the battery being charged. The voltage number (e.g., 12V) represents the electrical potential the charger delivers, while the current number (e.g., 2A) indicates the rate at which the charger can deliver power to the battery, affecting the charging speed. It's important to use a charger with appropriate numbers to ensure safe and efficient charging.
