Yes, a 9-volt battery can be charged with a 12-volt charger, but it's important to exercise caution. Charging a lower voltage battery with a higher voltage charger can lead to overcharging, overheating, and potential damage or safety hazards. It's advisable to use a charger specifically designed for the type and voltage of the battery to ensure safe and effective charging.
