In the spiral case, a PI heating film is attached spirally to the battery surface. The number of spiral turns is 3, and the height of the spiral line and the width of heating film is 14.6 mm and 14.3 mm, respectively. The contact area Sspi is around 25 cm 2 calculated as in Eq. 10.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
Do not put sealed lead acid batteries in airtight containers, or install the batteries in a room without ventilation. Gas generated by over charging reactions in the battery may explode if ignited by sparks from machinery or switches. Tightly screw the connector with the terminal of the batteries.
