This voltage indicator, shall work well with high input impedance transistors (JFET, MOSFET).
Simple and nice circuit but what happens when you have 12V or more on battery and adjust the variable resistor to zero ?

The LM3914 senses the voltage level at the input pin and drives the 10 light emitting diodes based on the voltage detected on input connector.
The three-IC power-supply system shown charges typical three-cell lead-acid batteries of the 6-V sealed D-cell type, and provides a manually activated check of the battery capacity. Lead acid batteries are comprised of a Sulphuric acid solution electrolyte, a sponge metallic lead anode and a lead dioxide cathode.
The result of all the reaction is a potential difference between the two plates where the positive plate gives up electrons and the negative plate gains them in equal numbers. To protect the batteries for the fear of being destroyed, the circuit provides the detection of discharge. On order to control the discharge of the battery, a stable voltage in a circuit is required to check the voltage. Lead acid batteries are being used in several industries because they are tried and tested, robust, tolerant to abuse and overcharging, low internal impedance, can deliver high currents, wide range of capacities and sizes, supplied worldwide, indefinite shelf life if stored without electrolyte, reliable, and low cost. Otherwise, the BJT will source some current to the trimmer and the voltage drop across the zener will not serve as a reference for activation or deactivation. Because of the chemical combinations, this heavy metal element is toxic and disposing it improperly would be hazardous to the environment. However, there is a limitation in the length of time for the reaction to produce the cell voltage. Since the lead acid battery has a voltage of 12 V, it is not allowed to be rated below 10.8 V. This can done using the IC1 LM723 which is a monolithic integrated circuit programmable voltage regulator, assembled in 14-lead dual in-line ceramic and plastic package. Also it is gives you enough time to get ready for a recharging or buy a new one in advance.


I have a bank of 4 all tied to a 400 watt wind turbine and with no load I get a discharge, can you help me out. The led glowed when voltage was high and didn’t glow when voltage was low, instead of the other way round. There were about ten different manufacturers and all failed after a while on 72 volt systems. IC1’s OFF terminal provides a means for disconnecting the charging voltage—a necessary condition for testing the battery’s capacity level.
Mechanically, the lead acid battery is made of a series of identical cells where sets of positive and negative plates comprise each cell. The voltage will remain constant without the presence of connection between the two plates. It can provide internal current limiting and an external NPN or PNP pass element may be used when the output current exceeds 150 mA.
Using wooden pallets is the best storage method since it will not allow damp paths, will not conduct, and will provide good air circulation.
The chemical reaction will be able to continue the electrons to flow through the circuit from the negative plate to the positive in the event that a load is placed between the positive and negative plates. Lead acid batteries should never run flat and the maximum recommended discharge is 75% of the total. A refreshening charge once every two months or more is recommended by most manufacturers during storage. This signifies that the minimum charge remaining on the battery should be around 25% before recharging.
Thin electrode plates allow a lot of energy to be discharged quickly for a short period of time like in car batteries. There are always one or more negative plates than positives because the arrangement of the positive plate is always in between the negative plates.
The battery will fail to produce any current when the supply of electrons becomes depleted.
Lead acid batteries should always be regularly charged even on its idle state once it has been filled with electrolyte. Thick electrodes in lead acid batteries can tolerate discharges better than thin but at the expense of producing heavier batteries.


The cause of this depletion may pertain to the electrolyte being turned mostly into water or the active material on the negative plate has been used up. The efficiency of the battery system depends on the heating levels of the chemical process wherein greater heating means the battery is quickly exhausted.
The sulphuric acid has the ability to distribute itself very evenly throughout the electrolyte in the battery due to its instability. The self discharge rate is a measure of how much the batteries discharge by them and is managed by the metallurgy of the lead used inside and the construction of the battery.
IC1 operates as a voltage comparator which compares the value of voltage between pin 4 and pin 5. This will always to an even reaction between all the plates by producing current and voltage. When the voltage in pin 4 is larger than the voltage in pin 5, the output in pin 9 becomes low. Both plates are turned into lead sulphate by the chemical reaction between the lead dioxide at the positive plates, the spongy lead at the negative plates, and parts of the electrolyte. But when the output in pin 9 becomes high, the LED will turn on as a result of the conduction of Q1. The regulation of the circuit requires an external power supply which can be regulated with a value of 10.8 V. The result of these comparisons either turns off the 5-V output (dead battery) or illuminates one of the four LEDs.
For a proper measurement, you should first open the charging circuit by momentarily closing the Battery Test switch—an action that causes IC1 to turn off Q1.
IC1 also limits the peak inductor current by turning off Q1 in response to voltage across the 0.075-? resistor Rsense. In this application, the load is an LDO (low-dropout) linear regulator (IC3), which generates 5 V at 500 mA. Finally, its shutdown capability (pin 4) lets the system turn off VCC to prevent a deep discharge of the battery.
