what is battery impedance testing and how we perform this
test with four wires.
Answer / binod
R=V/I
FIRST BATTERY TO BE FULLY CHARGED TO ITS RATED VOLTAGE.
+VE&-VE TERMINALS WIRES OF BATTERY CONNECTED WITH A VARRIAC
AND A VOLT METER ,AM METER CONNECTED THAN DIPPED INTO
ELECTROLYTE JAR. VARRIABLE VOLTAGE & CURRENT MEASURED WITH
DIFFERENT TIMINGS . AS THE BATTERY RATED IN AMPHR GRADUALLY
CURRENT DECREASE. BUT THE VOLTAGE OF BATTERY WILL NOT
DECREASE SO RAPIDLY. FROM THE ABOVE TEST RESISTANCE OF
BATTERY FOUND.
