Hello, I have seen graphs of Battery's DoD (depth of discharge) vs Life Cycles. But at the same time, "life cycle" is defined as the no. of COMPLETE charge-discharge cycles that a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. Here's the contradiction: From the definition, the term "life cycle" should only be valid for a DoD of 100% (or maybe 80%, whatever is the max. possible value). How can the battery's life be rated in terms of life cycle? In those graphs, does "life cycle" simply mean discharging to a specified amount (DoD) and then charging rather than COMPLETELY dscharging and charging the battery?
