Tackless plate formation
Formation of plates in containers without welding the plates together. The plates are resting with its lugs on lead bars. A connection of the lugs is created
through a short charging with the opposite polarity. In state of the art >> formation rectifiers integrated in the automatic program.

Tank formation
Formation conducted in tanks, the plates in each tank being in a parallel connection. Production method for dry charged plates respectively batteries.

Tnom
>> Temperature, nominal (Tnom).

Temperature, nominal (Tnom)
An electrolyte's nominal temperature is a specified value which is used as a reference value for capacity tests (e.g. according to European standard
EN 60095-1, Tnom lies in the region of 25+2 °C for the 20-hour capacity of lead batteries).

Terminal
Polarity-specific component on the battery for making a (detachable) connection with the consumer.

Thermal instability
>> Thermal runaway.

Thermal runaway
Continuous heating of the electrolyte up to the boiling point due to an increase in charging current an the charging voltage decreases
(lead accumulator with falling charge characteristic).

Tinning
Coating a metal surface with tin, either with tin enamel (fine tinning) or tin alloy (galvanic).

Traction battery
>> Battery, traction.

Tree formation
Describes the growth of a lead dendrite, in the case of a lead discharge, through a hole, a crack, or a large pore of a separator, such that the cell
becomes short-circuited.

Tubular plate
Positive plate manufactured from die-cast positive grids, gauntlets and filled with a mixture of dry oxide or wet paste.

Tubular plate filling machine
Positive tubular plates for traction or stationary cells can be filled in 2 different ways.
Wet filling: with a paste with a high density or
Dry filling: with lead oxide, sometimes mixed with red lead.
