Side-by-Side Comparison
Cylindrical Cells
AA Battery vs. C Battery
Comparing 2 standards across 3 specifications. 2 key differences identified.
Comparing:
AA Battery
C Battery
A standard AA battery measures 14.5mm in diameter and 50.5mm in length. Primary Alkaline cells output 1.5V, NiMH rechargeable cells output 1.2V. Inserting a 3.6V 14500 Li-ion cell into 1.5V AA devices destroys the circuit.
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.
