Circuit Test Battery by LM3914
Circuit Test Battery by LM3914
This be the checks battery circuit , that easy and perfect , because it shows with LED 10 level. And can check battery get many the size be 1.5V ,3V,4.5V,6V,9V,12V and choose the size current , of battery , get with , such as , 0.5Ah, 2Ah, 5Ah sizes etc. When see in my circuit uses the integrated circuit LM3914 , perform show the level voltage , the value is all , get 10 the level. This friends circuit must use power supply about 12V 60mA then appropriate usual usability. Other detail is friends see in the circuit better yes.
