In practical terms, a 3000mAh battery can supply a current of 3 amps for 1 hour before it is depleted. However, the actual runtime of a device powered by a Li-ion battery may be affected by various factors such as temperature, discharge rate, and age, which can reduce the effective capacity of the battery over time.

To maximize the lifespan and performance of a Li-ion battery, it is recommended to use a compatible charger, avoid extreme temperatures, and avoid deep discharging the battery. Additionally, some devices may have built-in battery management systems that help to optimize the charging and discharging of the battery to improve its overall longevity.
