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.
About Ampere-hours
The ampere-hour (Ah) equals exactly 3 600 C and is the universal capacity unit for rechargeable batteries. Lead-acid car batteries are rated 40-100 Ah; EV traction packs use 50-300 Ah cells; industrial forklift batteries exceed 1 000 Ah. Multiplying Ah by nominal voltage gives watt-hours of stored energy. 1 Ah = 3 600 C = 1 000 mAh.
