Simplest, most efficient and easiest to read battery tester ever yet
offered to the battery owner. Unlike any hydrometer or tester on the
market. Instead of the glass float used on ordinary hydrometers, which
are hard to read and understand, it has three balls, colored red, white
and green which tell the whole story.
Astonishingly simple to test a battery with it, because the following
jingle regarding the three balls, and the positions they assume in the
electrolyte or liquid tells the story—
“Floats all three, battery is charged fully.
Sinks the white, charge still right,
Sinks the green, charge is lean,
Sinks the red, charge is dead.”
A battery can be tested with it with as much accuracy as any hydrometer
on the market. The specific gravity of each ball is accurate to the
fourth decimal point. It can be “read” in semi-darkness.
Is only 6½ inches long and designed so that it can be carried in the
tool box where it is _Always Handy_—A mighty big value for only 75c.
Furnished to the Dealer in an attractive counter display box, one dozen
to each package. When placed on the counter it sells itself.
