The average temperature of the battery's surroundings

The average temperature of the battery's components.

An electrical conductor used in a cell to make external electrical connection to the cell plates.

A chain reaction in which the heat generated within the battery by the overcharge current lowers the battery's internal resistance. This, in turn, progressively increases the charging rate and the heat being generated. In the final stages, enough excess heat may be generated to destroy the battery.

Method of charging in which a secondary cell or battery is either continuously or intermittently connected to a constant current charging source that maintains the cell in a fully charged condition.

FAA approval authorizing a manufacturer to produce a product or part to a certain minimum standard. In Concorde's case this is TSO C173 - aircraft batteries.
