Full definition
Batteries mix unbranded category prompts, constrained scenarios, comparison questions, and occasional branded checks. Keeping wording stable enables trend lines; adding exploratory prompts is fine if they are labeled separately from the core panel.
Good batteries cover the intents that actually drive pipeline—not only vanity “best tools” lists—and include competitor names where fair comparison matters. Log model, mode (browsing on/off), locale, and date for each run.
Prompt batteries are the sampling frame behind share of model, citation rate, and competitive displacement studies. See Prompt, Visibility Probe, and Share of Voice.
Example
A B2B team runs 40 prompts monthly across ChatGPT and Perplexity, scoring whether each answer names their product in the top three recommendations.
