![]() ![]() To longer shelf life for circuit device operations. Powerbanki - 3000mAh - porwnanie cen telefonw komrkowych i akcesoriw do nich w sklepach internetowych. Thus, you can see how higher mAH values are more desirable in circuits, because it leads Power the circuit for 5 times as much as time as the AA battery cell can. Now the same circuit powered by a D cell battery rated at 10,000mAH can power the circuit for 10000mAH/200mA= 50 hours. Nominal Capacity: 3000mAh Nominal Voltage: 3.7V Discharge: 20A Max Continuous, Rated 35A Max Pulse by IMREN Positive: Flat Protected: NO, UNPROTECTED Rechargeable: Yes Dimensions: 18.49mm x 65.34mm Weight: 46. iWordQ is cost-effective, secure, and reliable you don’t even need an internet connection to use it. Great for students or anyone on-the-go who struggles with reading and writing. With a AA battery rated at 2000mAH, it can power the circuit forĢ000mAH/200mA= 10hours. iWordQ is an easy-to-use reading and writing app for iPads. I got similar results for the Anker PowerCore+. So, for example, let's say there is a circuit that consumes 200mA per hour. The S7 has a 3,000 mAh battery and the 3,100 mAh battery pack can charge it to 71. 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 Thus, our same example, of a 1900mAH battery can be used in the following ways, The product of the current consumed times the number of hours in use must equal 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
