Which component's battery capacity is described in hours (total operating time)?

• A. LIAC
• B. LBB
• C. Saber
• D. LRF

Answer: (B)

Battery life described in hours means the spec is giving how long the unit can run on a single charge under typical use. For the LBB, the manual lists total operating time in hours, which is the most practical measure for field planning—it tells you how long the system can function before a recharge or battery swap is needed. This endurance depends on both the battery’s stored energy and the device’s average power draw, so knowing the hours lets you estimate runtime by dividing the battery capacity (in amp-hours) by the current draw (in amps). In practice, if you know the LBB’s battery stores a certain amount of energy and the system pulls a certain current, you can predict how many hours it will operate before needing a recharge. Other components might express capacity in different units, but when you see hours, that’s the endurance figure you use for planning.
