A 26650 Li-ion cell measures 26mm in diameter and 65mm in length, used in high-drain devices like flashlights, power tools, and RC-hobby battery packs. The format is produced in multiple chemistries with different nominal voltages, so '26650' alone does not guarantee a specific voltage.

C Battery →

A C battery (IEC designation LR14, ANSI 14A) measures 26.2mm in diameter and 50.0mm in length. Alkaline C cells output 1.5V nominal, with typical capacity in the range of roughly 6,000 to 8,000 mAh -- well above AA or AAA but less common in modern consumer electronics.
