Battery discharge status indicator circuit

Posted on Mar 28, 2007

When the battery voltage is 7 ~ 12. 6V range, the light emitting diode VLi lights, which light cutting almost unchanged. If the battery voltage falls under 7V VLi beginning red light emitting diode, and a light emitting diode , L2 brightness decreases.

When the two are the same brightness light-emitting diode, the battery should be recharged or replaced. When the battery voltage when Yap in 2. 5 ~ 6V range, VLz red, battery voltage has forecast below normal. Select the appropriate indicator of the resistors and the regulator, can adapt to the needs of different monitoring battery voltage.
