Lead shedding is a natural phenomenon that can only be slowed and not eliminated. The terminals of a battery can also corrode. This is often visible with the formation of white powder as a result of oxidation between two different metals connecting the poles. Terminal corrosion can eventually lead to an open electrical connection.
Strip can be stored as coils and be used for any grid design, which can mean a lower inventory stock for battery manufacturers. The mechanical and chemical properties as dictated by the lead alloy grain structure can be manipulated by control of rolling pressures and degree of deformation.
NiCd batteries generally utilize a nickel plated recessed threaded terminal to receive a bolt or a threaded post which requires a nut to secure the intercell connector or cable. Cleaning cell terminals is conducted in a similar manner and with the same attention to the battery manufacturer’s instructions.
Popular types for lead-acid batteries include square post, recessed threaded insert, chair and flag to name a few. NiCd batteries generally utilize a nickel plated recessed threaded terminal to receive a bolt or a threaded post which requires a nut to secure the intercell connector or cable.
Unlike a soft short that develops with wear and tear, a lead drop often occurs early in battery life due to a manufacturing defect. This can lead to a serious electrical short with a permanent voltage drop that could result in thermal runaway.
The lead within a battery is mechanically active. On discharge, the lead sulfate causes the plates to expand, a movement that reverses during charge when the plates contract again. Over time, sulfite crystals form that cause shedding of lead material.

BU-804a: Corrosion, Shedding and Internal Short
Corrosion occurs primarily on the grid, and it is known as a "softening and shedding" of the lead off the plates. This reaction cannot be avoided because the electrodes in a lead acid environment are always reactive. Lead shedding is a natural phenomenon that can be reduced but not eliminated.
