9V Battery vs. AAAA
Comparing 2 standards across 8 specifications. 8 key differences identified.
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.
A AAAA battery (IEC designation LR8D425) is a 1.5V Alkaline cell measuring approximately 8.3mm in diameter and 42.5mm in length -- smaller than a AAA. It's used in devices with especially tight internal space, such as laser pointers, some styluses, and compact LED penlights.
