These batteries are designed for deep cycling and are
expected to be fully discharged on each cycle. Generally,
plates are relatively thick and large (flat in North America
and tubular in the rest of the world) and the battery is
expected to achieve a long cycle life.
The Amersil ‘‘S’’ corrugated separator has been tested in
two different types of traction flooded batteries. In the first
accelerated life cycle test performed at 47 8C, three 120 Ah
traction cells with tubular positive plates have been
assembled with corrugated S separator of 2 mm thickness
(Table 1) and compared to three identical cells assembled
with standard Amersil ribbed separator of the same thickness
(Table 1). The discharge has been achieved during 1.8 h
