Which code denotes the 14 volt DC selection battery?

Explanation:
Understanding how battery codes are assigned helps you read the system quickly. In this scheme, the code prefix S groups designate selection-related batteries, and the following letter differentiates the exact battery within that group. The 14-volt DC selection battery is labeled Sb, so that code identifies the correct battery. The other codes (Tb, Tc, TbX) correspond to different batteries or different voltages within the same overall system, so they do not denote the 14-volt selection battery.
