Debunking Battery Myths: Discharge Depths and Cycle Life of Lithium and Lead Acid Batteries

The video seeks to discredit the commonly held belief that Lithium Iron Phosphate batteries, or any other lithium polymer battery for that matter, can be discharged to 0% without any negative effects, compared to lead acid batteries, which are deemed weak and dead past 50% DoD. The narrator points out that while there is some truth to these statements, they ultimately mislead by implying lithium batteries, unlike lead acid batteries, are undamaged and have no shortened life when discharged to 0%. The reality is that both batteries show decreased life expectancies, more so when they are discharged significantly.
Further, the narrator addresses how the misconception may stem from the contrast between the sharply declining curve for lead acid compared to the gradual, near-linear drop for the lithium iron phosphate battery in terms of cycle life when DoD and cycle life are plotted. He emphasizes the importance of personally checking manufacturers' ratings for cycle life of a comparable lead acid battery to a lithium battery as they are commonly rated at 80% DoD. This will lead to informed comparisons based on the depth of discharge and accurate assessments. He concludes by stressing the importance of conducting your own research to avoid the trap of parroting possibly skewed information.
