2Ah
2Ah denotes a battery capacity rating of two ampere-hours. It is a measure of how much electric charge a rechargeable cell or pack can deliver at its rated voltage over time. The rating is nominal and depends on the chemistry, temperature, discharge rate, and end-of-discharge voltage.
One ampere-hour equals 3600 coulombs, so 2Ah equals 7200 coulombs. The stored energy also depends on voltage,
In practice, the runtime you get from a 2Ah pack depends on the load. At the stated
Applications of a 2Ah rating span a range of consumer and power-using devices. You’ll see it on
Charging and safety considerations include using a charger appropriate for the battery chemistry and capacity. A
