What is the total operating time of the LBB battery when fully charged?

• A. 12 hours
• B. 14 hours
• C. 13 hours
• D. 15 hours

Answer: (D)

Operating time is how long the battery can power the system on a full charge, based on the battery’s capacity and the current the system draws. If the LBB battery has a rated capacity and the equipment draws a steady amount of current, you estimate time by dividing capacity (in amp-hours) by the current draw (in amps). For example, a battery rated at 12 Ah with an average draw of 0.8 A would last about 12 ÷ 0.8 = 15 hours. Real-world factors like temperature, age, and fluctuations in load can shorten that time, but the 15-hour figure comes from the straightforward capacity-to-load calculation.
