In the charging process we have to pass a charging current through the cell in the opposite direction to that of the discharging current. The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy.
The most important first step in charging a lead-acid battery is selecting the correct charger. Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding voltage and current levels.
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. Sealed lead acid batteries may be charged by using any of the following charging techniques:
Proper monitoring during charging is crucial for safety and performance. Lead-acid batteries produce hydrogen and oxygen gases as they charge, particularly in the later stages of charging. These gases can accumulate and become hazardous if not properly ventilated.
Typical sealed lead acid battery charge characteristics for cycle service where charging is non-continuous and peak voltage can be higher. Typical characteristics for standby service type battery charge. Here, charging is continuous and the peak charge voltage must be lower.
The best way to get rid of unwanted lead-acid batteries is to ask a professional to take them away. This recycling option is also quite profitable and you can send your batteries to BatteryClerk for easy disposal.
