About Milliampere-hours
The milliampere-hour (mAh) equals exactly 3.6 C and is the universal capacity unit for portable-electronics batteries. Smartphone batteries range from 3 000-5 000 mAh; AA alkaline cells deliver ≈2 500 mAh; small lithium coin cells for RTC modules are rated 35-225 mAh. 1 mAh = 3.6 C = 10⁻³ Ah.
About Abcoulombs
The abcoulomb (abC) equals exactly 10 C - the charge unit of the CGS-EMU (electromagnetic) system, defined as the charge transported by 1 abampere (= 10 A) in 1 s. Two parallel wires each carrying 1 abampere and spaced 1 cm apart experience a force of 2 dyn per centimetre length. The abcoulomb appears in older electromagnetic engineering literature from the early twentieth century. 1 abC = 10 C.
