Replace a Cell in an Existing String
Introduction New Round Cells may be intermixed directly into an existing string of
older Round Cells (of the same capacity and acid specific gravity) when
necessary for replacement purposes. However, never mix different
AH-rated Round Cells in the same string.
Lucent Technologies recommends disconnecting the existing string
from the load and charger before replacing cells. However, if
circumstances require that a cell be replaced in an existing string without
removing the string from the plant bus, follow guidelines in “String
Connected to Load/Charger.”
