Was bedeutet mAh bei aufladbaren Batterien?
Durch die Angabe des mAh-Wertes kann man die Leistung des jeweiligen Akkus erkennen. Dabei ist mAh die Abkürzung für Milliamperstunden, also die im Akku gespeicherte Menge an Energie. Es wird der Wert errechnet, bei dem die Batterie konstant einen Milliamper abgibt.
Ist 3000 mAh viel?
Eine Milliamperestunde ist ein Tausendstel von einer Amperestunde (Ah). Hat ein Smartphone-Akku also eine Kapazität von 3000 mAh, so könnte man der Einfachheit halber also auch von 3 Ah sprechen. Da 3000 aber besser klingt als 3, setzen die Hersteller weiterhin auf die Angabe in Milliamperestunden.
What does Mah stand for in a battery?
The mAH specification of a battery stands for milliampere-hours. mAH is the amount of milliamperes which a battery can provide (to a circuit or device) for the amount of hours specified in its specification. Thus, a battery if a mAH specification of 1900mAH can provide 1900mA (milliamperes) for 1 hour of time.
What does Mah in milliamp hours mean?
(Milliamp Hours) mAh means m illi a mp H our and is a unit that measures (electric) power over time. It is commonly used to measure the energy capacity of a battery. In general, the more mAh and the longer the battery capacity or battery life. A higher number means that the battery can store more energy, so it has a higher capacity.
Which is better a bigger battery or a bigger Mah?
If you’re replacing the battery and you have the option of a 2500, 3500 or 4000mAh battery that are fully compatible, bigger is always better. Remember, the mAh is the measure of energy potential over time and not available power that can be delivered.
How many Mah does an AA battery consume?
D cells provide current for a longer period of time than all others. So, for example, let’s say there is a circuit that consumes 200mA per hour. With a AA battery rated at 2000mAH, it can power the circuit for 2000mAH/200mA= 10hours.
