Intercell connection resistance
Intercell connection resistance is a test of an intercell connection to verify its tightness and health. A battery is comprised of cells connected in a series path in order to produce a higher output voltage. The more cells in series the higher the vortage. The intercell connection binds these cells together. If any one component fails the entire series connection fails. Many times batteries fail, not because of weak cells, but due to weak intercell connections.
Each intercell connector is either a solid bar or a cable. Each end is bounded to the cell by a bolt or some other type of connector. If the connection is loose than the intercell connection resistance would increase. Also, temperature from that connection would increase because of the higher resistance which produces heat.
Higher resistance reading indicate a need to go through and tighten the connection bolts on each cell. Or, perhaps the connection material is degrading and should replaced.
