ime. Due to this fact, the Eveready battery is
called a "Non-Sulphating Battery."

The manufacturers state that Eveready batteries which have stood idle
or in a discharged condition for months do not suffer the damages
which usually result from such treatment, namely: buckling, and
injurious sulphation. The plates do become sulphated, but the sulphate
remains in the porous, non-crystalline state in which it forms.
Charging such a battery at its normal rate is all that is necessary to
bring it back to its normal, healthy condition. Due to the excessive
amount of sulphate which forms when the battery stands idle or
discharged for a long time, it is necessary to give the battery 50
percent overcharge to remove all the sulphate and bring the battery
back to a healthy working condition. The colors of the plates are good
guides as to their condition at the end of the charge. The positives
should be free from blotches of white sulphate, and should have a dark
brown or chocolate color. The negatives should have a bright gray or
slate color.

Description of Parts

Eveready plates are of two general types. Plates of the R type are
each provided with two feet on lower ends, the positive set and the
negative set resting on two separate pairs of bridges in the jars,
thereby preventing the sediment which accumulates on top of bridges
from short circuiting a cell.

Plates of the M type, instead of having feet, are cut away where they
pass over the bridges of the opposite group. See Fig. 261. This
construction secures a greater capacity for a given space, and gives
the same protection against short circuit from sediment as the foot
construction does, since the same amount of sediment must accumulate
with either type of plate to cause a short circuit.

The separators used in Eveready batteries are made of cherry wood
because it is a hard wood which will resist wear, is of uniform
texture, even porosity, and has a long life in a given degree and
condition of acid.

Eveready cherry wood separators go to the repair man in a dry
condition, as they do not require chemical treatment. Separators when
received should be soaked in 1.250 specific gravity acid for four days
or longer in order to expand them to proper size and remove natural
impurities from the wood. After being fully expanded they should be
stored moist as previously described. Stock separators may be kept
indefinitely in this sol
