A GREAT DEAL Of THE TROUBLE EXPERIENCED WITH BATTERIES IS LARGELY DUE TO THE TYPE OF HYDROMETER USED IN TESTING, AND CAN BE ELIMINATED BY USING THE PROPER HYDROMETER SHOWN HERE.
See Image above….
THE TROUBLE CAUSED BY USING THE IMPROPER HYDROMETER IS THIS: THE STEM Of THE HYDROMETER IS SO LARGE THAT IT DOES NOT ALLOW ENOUGH FLUID TO BE PICKED UP, NOR CAN IT REACH DEEP ENOUGH INTO THE CELLS. AS A RESULT, IT IS TAKEN FOR GRANTED THAT THE BATTERY IS DRY, THE BATTERY IS THEN FILLED WITH TOO MUCH WATER WHICH RESULTS IN A GAS FORMING INSIDE THE CELLS THAT FORCES THE ELECTROLYTE OUT OF THE BATTERY ONTO PARTS OF THE MACHINE.
THE ABOVE PHOTOGRAPH SHOWS THE CORRECT TYPE OF HYDROMETER FOR USE IN TESTING MOTORCYCLE BATTERIES. THE STEM IS SMALL ENOUGH TO REACH INTO THE CELL TO PICK UP ENOUGH FLUID TO OBTAIN A PROPER READING AS TO THE CONDITION OF THE BATTERY. THIS HYDROMETER IS KNOWN AS NUMBER “H-161” AND IS SOLD BY “WILLARD” STORAGE BATTERY DISTRIBUTORS.
If YOU DO NOT NOW HAVE THIS SMALL TYPE HYDROMETER, WE RECOMMEND THAT YOU GET ONE AS SOON AS YOU CAN.
