   5. Battery General Notes
      
      
      1. During discharging, the Negative battery plate is lead, and the Positive plate is lead dioxide, both becoming lead sulfate. The alloying of both plates with small amounts of calcium gives strength to the plate and helps inhibit corrosion.
         
         
      2. The one-way battery valve ensures that no air can enter the battery; thereby it obviates the possibility of oxygen reaction with the plates. The vent release pressure is 2 to 6 PSI.
