Cómo hemos elaborado este informe
Specs were sourced by WebFetching manufacturer product/spec pages where accessible. Several manufacturer and major-retailer domains (ctek.com, batterytender.com, home depot, walmart, autozone, lowes, revzilla, batterystuff, target, batteryguys, jegs) returned bot-block responses (HTTP 403/429 or CAPTCHA challenges) throughout this session despite repeated attempts at spaced intervals; for those products, specs were instead sourced from the manufacturer's own PDF/owner's-manual text as mirrored on ManualsLib (a manual-hosting aggregator, not a spec-marketing site), and cross-checked against the actual manufacturer-hosted product photograph (visually inspected) to confirm model identity and read faceplate-printed ratings, mode buttons, and indicator/display type directly off the unit. priceUsd is left null wherever no accessible primary source (manufacturer store or retailer page) displayed a concrete USD figure during this session -- several manufacturer brand microsites (Schumacher, DEWALT-licensee) publish specs but no price at all (retailer-set pricing). No spec was invented to fill a gap; null is used throughout in place of a guess.
