The energy stored in a battery can be calculated using the formula: Energy (in watt-hours) = Voltage (V) × Capacity (A-h). For this battery, Energy = 12 V × 160 A-h = 1920 watt-hours. Converting watt-hours to joules (1 watt-hour = 3600 joules), the energy is 1920 × 3600 = 6,912,000 joules, or 6.9 MJ.
