Load Test
This is the best test of battery condition under starting loadUse load testing device that has an adjustable loadApply load of times the ampere-hour rating of the batteryAt 14 seconds into the test, check battery voltage; if battery is in good condition, it will have at least 10.5 Vdc

TYPICAL 1Specific gravity 1.265
A hydrometer measures the charge of battery in terms of specific gravity of the electrolyteMost hydrometers give true reading at 21C (70F)In order to obtain correct readings, adjust the initial reading by adding .004 points to the hydrometer readings for each 5.5C (10F) above 21C (70F) and by subtracting .004 point for every 5.5C (10F) below 21C (70F)This chart will be useful to find the correct readingELECTROLYTE TEMPERATURE 38 32 27 21 16 10100 90 80 70 60 50 40 30 subtract add .012 .008 .004 correct reading .004 .008 .012 .016 from the reading to the reading OPERATION TO PERFORM
