14500 vs. 9V Battery
Comparing 2 standards across 7 specifications. 7 key differences identified.
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.
A 9V battery (IEC designation 6LR61, commonly called PP3) is a rectangular battery measuring approximately 48.5mm x 26.5mm x 17.5mm with two snap terminals. Alkaline 9V cells output 9.0V nominal from six internal 1.5V cells in series, with typical capacity around 400-600 mAh.
