What is milliampere-hour (mAh)? | Definition from TechTarget
When considering AA to D cell batteries, AA batteries usually have the shortest mAH life, while D cells have much greater mAH. A AA battery may have a mAH of 2000, while a D cell may have 10,000mAH. For this reason, D cells are physically bigger and are more expensive than C or AA batteries.
Battery life = Battery capacity in mAh/Load current in mAh In other words, the higher the load current will make the battery life shorter, and vice versa. For instance, 25 hours and 5 minutes will have to pass before needing to recharge a 5000 mAh battery connected to a Samsung Galaxy A9 Pro with a load current of 195mA in talking mode.
