12V SLA LEAD ACID BATTERY CHARGER USING BQ24450

12V SLA LEAD ACID BATTERY CHARGER USING BQ24450

This project has been developed to charge SLA (Lead Acid Batteries) . It helps to charge 12V Lead-acid battery up to 12Ah in capacity. Specific current output is possible by altering the current sense resistor.  The BQ24450 chip contains all the necessary circuitry to optimally control the charging of valve-regulated lead-acid batteries. The IC controls the charging […]
