Abstract
The problem of negative plate self-discharge in flooded lead-calcium cells is addressed. Two aspects of the problem are discussed. The first is quantification of negative plate self-discharge through recharge testing. The second is the benefits and drawbacks of equalizing the cells by the method of increasing the float voltage from 2.17 to 2.20 Vpc. Float operation, temperature effects, and polarization calculations are also discussed.<>
