Application Notes
- U-131 Simple Switchmode Lead-Acid Battery ChargerPDF, 206 Kb, File published: Sep 5, 1999
Lead-acid batteries are finding considerable use as bothprimary and backup power sources. For complete batteryutilization the charger circuit must charge the batteryto full capacity while minimizing over-charging forextended battery life. Since battery capacity varies withtemperature the charger must vary the amount of chargewith temperature to realize maximum capacity and life.Si
