- The Union Carbide Battery Products Division was actively marketing consumer battery accessories under the EVEREADY brand during this postwar period.
- The R-1798B model appears in listings and collector databases as a 1940s-era diagnostic tool, Bakelite casing, which was common in that era.
Original R-1798B battery tester manufactured by Union Carbide Corporation, Battery Products Division, New York, NY. This mid-century diagnostic tool was designed for testing AA, AAA, C, D, 9V, and lantern batteries, with labeled settings for toys, clocks, flashlights, and cameras. Features a needle gauge with color-coded voltage zones and a rotary selector switch. Likely produced between 1947 and 1953, during Union Carbide’s peak consumer battery era under the EVEREADY brand. A classic example of postwar American electronics, ideal for collectors of vintage tools, electrical memorabilia, or EVEREADY products.
