About the Lead Acid Battery | Battery Council International
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.
Technology Strategy Assessment
The lead-acid (PbA) battery was invented by Gaston Planté more than 160 years ago and it was the first ever rechargeable battery. In the charged state, the positive electrode is lead dioxide (PbO 2) and the negative electrode is metallic lead (Pb); upon discharge in the sulfuric acid electrolyte, both electrodes convert to lead sulfate (PbSO 4 ...

Lead Acid Battery Install and Maintenance Tips
If you are properly charging a lead acid battery bank to full on a regular basis, you should never have to EQ a battery bank. If you have developed a difference in measured SG''s of more than .025 to .030 points then a corrective EQ may be required. Corrective Equalizations should be performed when the battery bank is at 100% SOC.
