Lead Acid Battery. Definition: The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost.The circuit shown in Figure 1 charges leadacid batteries in the conventional way: A currentlimited power supply maintains a constant voltage across the battery (approximately 2. 4Vcell, as specified by the battery manufacturer) until the charging current decreases below a current threshold defined by the capacity of the battery. lead acid battery charging schematic

The circuit diagram of 12V lead acid battery charger is shown in figure 1. This circuit is built around fixed voltage regulator, variable voltage regulator, dual operational amplifier IC, Transistor, Relay, Transformer and few other electronic components.

LeadAcid Battery Charging Methods The leadacid battery stores chemical energy and this energy is converted into electrical energy whenever requires. The conversion of energy from chemical to electrical is known as the charging. This paper describes a compact leadacid battery charger, which achieves high efficiency at low cost by utilizing switchmode power circuitry, and provides high charging accuracy by employing a dedicated control IC. The circuit described can be easily adapted to lower or higher power applications.lead acid battery charging schematic The lead acid chemistry is fairly tolerant of overcharging, which allows marketing organizations to get to extremely cheap chargers, even sealed lead acid batteries can recycle the gasses produced to prevent damage to the battery as long as the charge rate is slow.

Lead Acid Battery Charger Circuit Diagram: The Vout of the LM317 is given to the battery which is to be charged, pin1Adjustment pin of the LM317 is connected to the transistor Q1, Resistor R1, R2, R5 which will help to adjust the regulator. The output of regulated lead acid battery charging schematic This high power lead acid battery charger circuit can be used for charging large lead acid batteries in the order of 100 to 500 Ah, the design is perfectly automatic and switches of the power to the battery and also itself, once the battery gets fully charged. Simple Circuit Charges LeadAcid Batteries. The charging voltage involves a tradeoff between cell life and charging time. High voltage minimizes the time required, but at full charge it produces a large overcharging current that shortens the battery's life by oxidizing its grid. To save battery life at the expense of charging time, Hi Chenwie a lead acid battery should be charged through constant voltage with the current limited 30 of the rated capacity of the battery or with limited 10 for 12 hours. Here LM317 with R3 R2& R5 takes care of regulating the voltage to 14 volts. To limit the current to 10 of the capacity R1 Q1 R4 is used. the circuit as the battery charger moves from precharge mode to CC mode to CV mode and then toward termination.
