Side-by-Side Comparison Cylindrical Cells

14500 vs. N / LR1

Comparing 2 standards across 4 specifications. 4 key differences identified.

Comparing:

A 14500 Li-ion cell measures 14mm in diameter and 50mm in length -- the same physical size as a standard AA battery -- but delivers 3.7V nominal rather than an AA's 1.5V. Because it fits mechanically into AA-sized battery holders, mixing it up with a real AA can destroy 1.5V-only circuitry.

N / LR1 →

An N battery (IEC designation LR1) is a 1.5V Alkaline cylindrical cell measuring approximately 12.0mm in diameter and 30.2mm in length -- between a AAA and a AA in size. It was historically common in pagers and remains used in some medical devices and specialty flashlights.
