For years, B batteries have been designed and con¬ 
structed to do a number of different jobs, such as supplying 
power for public address systems and small radio trans¬ 
mitters and car radios, as well as giving the life and service 
necessary on farm radio sets. 
Now, we have a battery that is designed and constructed for 
one job, and one alone! and that is operating' the farm radio most 
efficiently. 
The average farm radio requires a fairly low current supply, but 
the voltage should hold steady over long periods of service, often 
running as high as two years. Only the very purest ingredients 
and special long life construction features can give this kind 
of service—here it is for you in this Special Farm Radio Battery. 
KM A Super Giant B Battery 
For the big radio or any purpose requiring plenty of power, the 
big Super Giant B battery will give you the best results. Con¬ 
structed to deliver the maximum number of service hours under 
heavy drain. The largest size B battery built for standard radio 
service, and recommended for heavy service conditions. 
Tell Me About the Service Yon Have Received 
From KMA "B” Batteries 
I am interested in knowing the kind of service they have given 
on your radio. For the best service report on KMA B batteries 
that you may have used any time within the past 7 years, I am 
going to give you either a new set of B batteries for your radio 
or a new set of tubes, as you may prefer. All reports must be 
mailed by March 1st. 
Test My New Farm Service ? -B” Battery 
On Tour Own Badio 
Put it along side of any Heavy Duty B battery that you 
care to purchase locally. If my special long life B battery 
does not outlast the other battery, I will give you a new 
battery absolutely free, providing the dealer from whom 
you purchased the other battery agrees to do the game 
thing. 
If you wish to make this test on your own radio, write 
in for contest blanks. I will send you three copies. One 
for your local dealer, one for yourself and one to be re¬ 
turned to me. You are to be the judge as to which battery 
gives the best service.

13 plate 
For those who want a good, stand¬ 
ard construction battery similar to 
those supplied for new car equip¬ 
ment, I recommend the standard 
type 13 plate battery. 
For special winter service, I 
recommend the 15 plate special bat¬ 
tery, which is designed for use in 
place of the 13 plate size in cars 
such as Fords, Chevrolets, Ply- 
mouths, etc.
