Analysis of the Performance Parameters of Lead Acid Batteries With Different Charging Cutoff Voltages

The desire to have compact, high power sources with low environmental impact has focused attention on solar batteries. The actual field conditions expose a battery to different charging voltages which occurs due to improper design, equipment failure, low radiation or any other factor. This paper reports the performance of solar battery with different charging cutoff voltages in the terms of Amp-hour capacity, temperature, Wh capacity etc. In this study flooded lead acid battery of 12V nominal voltage and 20Ah of capacity was analyzed at different charging cutoff voltages by using Bitrode LCN battery tester. The experiment was performed with varying charging cutoff voltages and analyzed the other performance parameter with respect to different charging cut-off voltages. In this paper, results from the data analysis of this experiment are presented which could help in predicting the behavior of flooded lead-acid batteries under various operating conditions and can also provide an inside view of battery performance on different charging voltages to the charge controller manufacturers.
