How do you determine the safe amp load of a battery tester?
I am looking at testing a battery on a 2012 Mazda 3 sport which has a Mazda factory battery 75D23L (52).
The service manual states in the testing procedure that the Battery load test current should be 195 A.
I have a budget load tester which does increments of 100 A. It states in the operating instructions: "Round the battery number down to the nearest 100".
Now my gut says 195A is close enough to 200A, but what if...
If I drop the 100A, then the test seems like it would be no good. It would only be testing half the draw and may falsely pass.
200A is only about 2.6% higher than 195A. Would 3% over be too much?
