26650 vs. AAA Battery
Comparing 2 standards across 4 specifications. 4 key differences identified.
Comparing:
26650
AAA Battery
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.
A AAA battery (IEC designation LR03, ANSI 24A) measures 10.5mm in diameter and 44.5mm in length. Alkaline AAA cells output 1.5V nominal; NiMH rechargeable AAA cells output 1.2V. Typical alkaline capacity runs roughly 800 to 1,200 mAh depending on discharge rate.
