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.
About Faradays
The faraday (F) equals the Avogadro constant times the elementary charge - N_A × e ≈ 96 485.33 C per mole - and is the fundamental unit of electrochemical charge (Faraday's law: 1 F deposits one gram-equivalent of any substance). Depositing 1 g of silver (Ag⁺, M = 107.87 g/mol) requires 96 485 / 107.87 ≈ 894 C ≈ 0.00927 F; plating copper (Cu²⁺) requires 2 F per mole. 1 F ≈ 26.801 Ah ≈ 96.485 kC.
