Currently, CSB Battery (Vietnam) manufactures small valve-regulated lead-acid (VRLA) batteries* (so-called sealed battery) with the tank formation method (See the chart below). This project introduces container formation method to some production lines, and about 60% of CO2 from fossil fuel combustion is reduced by integrating formation and charging processes, which consume much of energy in the 11-step battery production, and eliminating a drying process and LPG usage. Furthermore, this new formation method reduces water consumption by removing washing step.

(*Compared to flooded lead-acid battery, it doesn’t need to refill water and is utilized in various ways, such as in uninterruptible power supply (UPS).)
