- Total listing price is divided by the canonical battery count extracted from the product title. batteries is best compared by battery count, not by pack size or weight. Marketing labels like a "family size", a "value pack", or a "mega" box hide the real battery count, so Dealophant extracts the true number of batteries from each title before dividing price by it. Cross-unit listings (for example a serving-count tub mixed in with weight-based tubs) are shown separately under "Other formats" so the price-per-battery ranking stays apples-to-apples.

- Usually yes, but not always — Dealophant has seen single-pack batteries undercut bulk on a per-battery basis when the smaller size is on sale or has a Subscribe & Save discount the bulk listing doesn't. That's why Dealophant always recomputes per-battery price live rather than assuming bigger = cheaper.
