Following incorrect charging procedures or using inadequate charging equipment can result in decreased battery life and/ or poor battery performance. The selection of a suitable SLA battery charger and the methods used to charge it is just as important as choosing the right battery for the application. Power Sonic recommends you select a charger designed for the chemistry of your battery. This means we recommend using a sealed lead acid battery charger, like the the A-C series of SLA chargers from Power Sonic, when charging a sealed lead acid battery.

E&O.E HOW TO CHARGE LEAD ACID BATTERIES BATTERY CHARGING TECHNIQUES Sealed lead acid batteries may be charged by using any of the following charging techniques: Constant Voltage Constant Current Taper Current Two Step Constant Voltage To obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant voltagecurrent limited charging is best. To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off. During charge, the lead sulfate of the positive plate becomes lead dioxide. As the battery reaches full charge, the positive plate begins generating dioxide causing a sudden rise in voltage due to decreasing internal resistance. A constant voltage charge, therefore, allows detection of this voltage increase and thus control of the current charge amount. BATTERY CHARGING CHARACTERISTICS During constant voltage or taper charging, the battery’s current acceptance decreases as voltage and state of charge increase. The battery is fully charged once the current stabilizes at a low level for a few hours. There are two criteria for determining when a battery is fully charged: (1) the final current level and (2) the peak charging voltage while this current
