b) the test probe tips/fingers make a good connection, piercing any
grease, lead oxide or crud coating the posts or straps. This is the leading
cause of error messages after pressing the test button. Often jiggling the
probe will lower the readings significantly and save you the heartache of
unnecessarily reworking a connection.

SINGLE INTERCONNECTIONS
Figure 1 shows how the Albér Cellcorder should ideally be connected to
obtain the proper measurement. Note that, ideally, the reading includes
both the intercell connector resistance and the post to intercell connection
resistance.
Figure 2A shows the connection for VRLA cells, such as the
ABSOLYTE II batteries, where the terminal post
is
accessible. Figure 2B
shows the connection for VRLA cells where the terminal post is
not
accessible. In this type of cell, the intercell to post connection resistance
is included in the internal cell resistance measurement. NOTE: Do
not
connect to the stainless steel bolt heads to make this measurement.
