About 
Threaded 
Rubber 
Insulation 
This trade-mark 
ia branded in red on 
one 3ide of the Still 
Better Willard — 
the only storage 
battery with 
Threaded Rubber 
Insulation. 
Q. What is Threaded Rubber 
Insulation? 
A. A storage battery insulating- 
material made up of rubber 
pierced with thousands of tiny 
threads. 
Q. How does it differ from oth¬ 
er battery insulation? 
A. Ordinary insulation is wood, 
cut in the form of thin sheets, 
and is neither as uniform nor 
as durable as Threaded Rub¬ 
ber Insulation. 
Q. Why is insulation so impor¬ 
tant? 
A. Because battery life depends 
largely on insulation and be¬ 
cause any defect or weakness 
of insulation is quickly evi¬ 
denced by buckled plates, 
short circuits, failure of the 
battery to hold its charge and 
so on. 
Q. What has this insulation to 
do with battery shipment? 
A. The kind of insulation deter¬ 
mines whether the battery must 
be kept wet, or can be shipped 
in “bone dry” condition. Wood 
insulation must never be 
allowed to dry out, hence 
makes necessary wet or par¬ 
tially wet shipment. With 
Threaded Rubber Insulation 
the battery can be shipped ab¬ 
solutely “bone dry.” 
Q. Why is “bone dry’’shipment 
and stocking preferable? 
A. Because it is the only method 
by which chemical action in 
the battery can be entirely 
held up, so that the battery 
reaches the buyer in truly 
brand-new condition. 
Q. Why does wood insula¬ 
tion need to be replaced? 
A. Because wood insulation being 
soft, wears out more rapidly 
than any other part of the bat¬ 
tery. It is also subject to 
cracking and checking, which, 
if allowed to go too far, serious¬ 
ly damages the battery. 
Q. Why does Threaded Rub¬ 
ber Insulation outlast the 
battery? 
A. Because the basis is hard rub¬ 
ber which resists wear and does 
not crack or check. 
Q. How can I be sure my bat¬ 
tery has Threaded Rubber 
Insulation? 
A. Look for the red Thread-Rub¬ 
ber trade-mark. It can be 
found only on the Still Better 
Willard Battery. 
Q. How many car and truck 
manufacturers have se¬ 
lected Threaded Rubber In¬ 
sulation? 
A. 136 in all. The complete list 
is printed at the right.
