Is ADP or ATP more like a fully charged battery, and why?

• ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
