The circuit has four units: voltage level indicator, automatic charging and overcharging protection, light control and power supply. When the battery voltage is less than the threshold value, the relay energises to connect the battery to the charging source. It also prevents overcharging by constantly monitoring the battery voltage level. Batteries Rice University This voltage is called the nominal cell voltage and differs among various battery technologies. For example, a standard flashlight cell uses a carbon zinc reaction and has a cell voltage of 1.5 Volts. Most car batteries have six lead acid cells, each with a cell voltage of 2.0 Volts (yielding the 12 volt battery). Capacity LED DC Voltage Indicator ElectroSchematics This LED DC voltage indicator circuit is a voltmeter, rather than simply a battery tester. As such it may measure voltages as low as 3V. It utilizes venerable LM741 operational amplifiers applied as comparators that drive LED indicators. Voltage thresholds are 3, 6, 9 and 12V. Above each incremental threshold an additional LED turns on. Very Simple Low Voltage Battery Alert | All About Circuits Was looking for ideas on the simplest way to indicate that a 12V Lead Acid battery has reached a low level, somewhere between 12.2V 12.4V. In other words, a low voltage dectect circuit. The one real stipulation is that it must run off the battery itself. Perhaps using a 9V zener to power a...
