Thus, you can see how higher mAH values are more desirable in circuits, because it leads If it was a 3V battery, for example, it would have 9,000 mW hours, or 9 W hours, of energy available. Power the circuit for 5 times as much as time as the AA battery cell can. mAh is an approximate measure of the energy available from the battery if you know the voltage.

Now the same circuit powered by a D cell battery rated at 10,000mAH can power the circuit for 10000mAH/200mA= 50 hours. Oryginalny zestaw VOOPOO Argus MT 100W Smart Mod 3000mAh bateria 5.
With a AA battery rated at 2000mAH, it can power the circuit forĢ000mAH/200mA= 10hours. So, for example, let's say there is a circuit that consumes 200mA per hour. D cells provide current for a longer period of time than all others. Reason, D cells are physically bigger and are more expensive than C or AA batteries. A AA battery may have a mAH of 2000, while a D cell may have 10,000mAH. So batteries with higher mAH's are more desirable, because they can last for a longer period of time, since they have a higher current capacity.ĪA batteries usually have the shortest mAH life, while D cells have much greater mAH. The circuit's power requirements, how much current the circuit demands.īeing that the mAH is the battery's life in terms of current capacity, the more mAH's means the longer a battery can last, or the more current it can supply in a circuit.

The mAH specification shows how long a battery will be able to last in a circuit, given Attom Tech USB Output Super Slim Power Bank Ultra Thin 3000mAh Portable Charger, Micro USB and USB-C Dual Input Ports Mini External Phone Battery Pack Small Emergency Phone Power Backup (Black) 4.2 (323) 179926.99. Thus, our same example, of a 1900mAH battery can be used in the following ways, Rechargable battery makes this electronic drum set plays 10 hours. The product of the current consumed times the number of hours in use must equal Visit the IWORD Store 12999 FREE Returns Coupon: Apply 10 coupon Terms About this item PLAY THE DRUMS ANYWHERE - IWORD portable electronic drum set is powered by the included adaptor. Or for other circuits, it can supply 190mA of current for 10 hours, since 190*10=1900. In this case, the battery supplies 380mA forĥ hours, since 380*5=1900. Usually a circuit will not demand 1900 mAH of current all at once for operation.Ī circuit may instead only need 380mA of current for operation. Again, as an example, a 1900mAH battery can supply 1900mA of current to a circuitįor one hour, and then it will have used all of its charge. Again, mAH, iillliampere-hours, show how many milliamperes of current the battery can
