When I needed extra power I could push a momentary button to activate the starter solenoid to connect it to the main battery. If ever the main battery was down on power the second battery could kick in the needed wattage (volts and amps). So I can understand how @MisterBill2 claims the second battery won''t be fully charged. Full enough for sure

It may be heavier than your original battery. Put a SMPS (switch mode power supply) that can withstand the maximum motor current - it will be expensive. The power supply must be enclosed this way so no water can reach it. Put a SMPS that is designed to work with a battery and also put a battery smaller than original.
