A battery pack selectively coupled to a portable electronic device and/or a recharging source, and configured to inhibit corrosion with discharge blocking features, the battery pack includes a positive terminal, a negative terminal, and a data terminal accessible from a housing of the battery pack, wherein each of the positive terminal, the negative terminal, and the data terminal are coupled to a battery in the battery pack; and a discharge blocking circuit configured to allow/block voltage across the positive terminal and the negative terminal based on a presence of a steady state pull up on the data terminal, wherein the steady state pull up is based on the battery pack being coupled to the recharging source, via the positive terminal, the negative terminal, and the data terminal.
