Voltage, Current, Resistance, and Ohm''s Law
For this example, we have a 9 volt battery and a red LED with a current rating of 20 milliamps, or 0.020 amps. To be safe, we''d rather not drive the LED at its maximum current but rather its suggested current, which is listed on its datasheet as 18mA, or 0.018
7. All features and settings
The "Charge Efficiency Factor" compensates for the capacity (Ah) losses during charging. A setting of 100% means that there are no losses. A charge efficiency of 95% means that 10Ah must be transferred to the battery to get 9.5Ah actually stored in the battery.
