mAh1000

mAh1000 is not an official designation in battery standards. It generally denotes a rechargeable battery rated at 1000 milliampere-hours (mAh). The mAh rating indicates the amount of charge the battery can deliver before it is depleted. In practical terms, 1000 mAh means the battery could supply 1000 milliamps for one hour, or 100 milliamps for ten hours, at a suitable voltage and under a specific discharge condition.

Real-world runtime depends on device power draw, voltage, age, and temperature. Batteries in consumer electronics are defined by their nominal voltage; for lithium-ion chemistries used in most small devices, this is commonly around 3.6–3.7V. The energy stored is often expressed in watt-hours (Wh) and is calculated as voltage × capacity in ampere-hours. Thus a 1000 mAh cell with a 3.7V nominal voltage stores about 3.7 Wh of energy.

Factors such as aging, temperature, and high discharge rates reduce usable capacity. The label "1000 mAh" does not guarantee a fixed runtime across different devices or conditions.

Applications and context: mAh ratings are common on small rechargeable cells, power banks, wearables, and wireless accessories. When comparing batteries, consider both mAh and nominal voltage and, if possible, the energy in watt-hours to estimate runtime more accurately.
