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 Kiloampere-hours
The kiloampere-hour (kAh) equals 3.6 × 10⁶ C = 3.6 MC, the practical unit for grid-scale battery storage and large industrial electrolysis. A 100 MW·h utility-scale lithium-ion installation delivers roughly 27 kAh at typical operating voltages; aluminium Hall-Heroult cells consume approximately 13 500 kAh per tonne of aluminium. 1 kAh = 10³ Ah = 3.6 MC.
