Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: 1. the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis. "Charged" does not necessarily refer to fully or 100% charged, but rather to the
