The answer is yes. A 12-volt battery can be charged as long as the output voltage of the 65-watt charger is 12 volts. The output current of the 65-watt 12-volt charger can reach more than 5 amps, which is sufficient for a battery with a smaller capacity (less than 60 amps). If the capacity of the battery is too large (much larger than 60 amps), the power of the charger 65 watts is insufficient, and a charger with larger power needs to be considered.
Can charge, 65w charger, charge 12 volt battery charge time is longer, you can change to a larger wattage charger
