Based on the above description, must assume the wet cell units were 8D
configuration.
The 8D package was designed as a cranking motor (starting) battery for
large diesel engines used in buses and over the road trucks.
It was not designed to be a deep cycle battery and to the best of my
knowledge, there has never been a deep cycle plate design developed for
an 8D housing.
The test results of deep cycle tests on an 8D battery should be viewed
with this information in mind.
An 8D package would not be my choice for a house bank for a lot of
reasons including weight of the unit as well as the fact it is being
misapplied in a deep cycle application.
