< Back Battery Charger A device that replenishes the energy of a discharged battery. A battery charger restores electrical energy to depleted batteries through controlled voltage and current. Modern smart chargers include automatic modes that prevent overcharging and maintain optimal levels. They support multiple chemistries such as lead-acid, AGM, and lithium. Regular charging extends battery life and ensures reliable starting performance. For workshops, using intelligent chargers during diagnostics prevents power drops that could corrupt ECU data. Always follow safety procedures when handling high-current charging equipment. Previous Next Related Diagnostic Guide This topic is part of CHEPQ’s system-level diagnostic framework.
