What are the voltage and amp hour specifications of the auxiliary battery?

The correct choice highlights the specifications of the auxiliary battery as 24 VDC and 5 amp hours. This specification reflects the typical requirements for systems that utilize a higher voltage for efficient power transfer and operational effectiveness. The 24 VDC provides a suitable voltage level for various electrical components, ensuring they operate optimally without excessive current draw, which could lead to inefficiencies or overheating.

The amp hour rating of 5 indicates the battery's capacity to deliver a continuous current over a specified period. This capacity is relevant for understanding how long the auxiliary battery can support connected devices before needing a recharge.

In contrast, the other options either suggest different voltage levels or a higher amp hour rating, which does not align with standard auxiliary battery specifications relevant to typical applications in this context. For instance, a 12 VDC battery is often used for smaller systems or less power-intensive applications, and while higher amp hour ratings like 10 may provide more capacity, they are not representative of the auxiliary battery specification under discussion here.
