毫安时(mAh)是主单位安时(Ah)的小单位。1Ah=1000mAh 毫安时是电量的单位。1毫安时=3.6库仑 当电流强度用毫安(mA)作单位,时间用小时(h)做单位,它们两个相乘就是毫安时(mAh),当然还是电量,由于1A=1000mA,1h=3600s,所以1mAh=3.6库仑。
它扇动它的四个翅膀起飞和飞行,并能之前,其90毫安时电池需要补足,以在空中停留约2.5分钟。
It flaps its four wings for take off and flight and is able to stay aloft for about 2.5 minutes before its 90 mAh battery needs topping up.
平面能源正在研发三种不同的电池化学配方。 其中之一是把锂锰氧化物与其他离子化合,充电电压三到五伏,容量200毫安时每克。
One of them combines lithium manganese oxide with other ions, and operates at about three to five volts with a charge capacity of 200 milliamp hours per gram.
想下这些数字(来自ARM),一颗1000毫安时容量的电池 Intel Atom Z500 处理器在频率800MHz运行时能支持19个小时的休眠时间,7小时的正常使用时间;
For a 1000 mAH battery, the Intel Atom Z500 Atom processor running at 800 MHz offers 19 hours of sleep time and overall battery life of 7 hours.
