Class 2 battery charger 12V lead acid battery consists of a microcontroller to manage the charging profile for accurate and automatic charging. The 12V charger is protected against destructive electrostatic discharge(ESD), and provides surge immunity against electrical overstress(EOS) to prevent damage to the internal circuitry. Additional features of the 12V Lead Acid Battery Charger include: Reverse polarity protection Short circuit protection Backfeed protection(BFP) Cell detection and pre-charge if the cell is over discharged Spark proof LED to indicate charge status Approved and Certified to UL/cUL1310 & IEC 60335-2-29 C8 AC power connector
