A battery load test takes about 30 or 40 seconds much more and you will
damage something (including the test equipment). However, the battery being
tested must not have been charged for at least 24 hours. Not by the vehicles
charging system or any other charging method.
The only way to do a true load test is to let a battery "rest" at least 24
hours after being fully charged.
That means you can not just drive in and say, "check my battery" and expect
to get a truthful answer. Because your battery has not had a rest period and
even if it is "junk" it could pass the test.
When you do the load test, you pull down the battery (1)noting how much
power you started with (2) how long it took to drop (3) to what level it
dropped to.(4) Then you need to check voltage in 15 minutes (no more) (5)
recheck voltage in about an hour from the first test. (6) Then hit again,
wait 15 minutes (no more) and see if it still can regain at least a 12 volt
charge.
If it passed the test it a good battery, otherwise get a new one.
What I understanding from your Sears experience, is that you got ripped!
If your telling me that you took them a dead battery and they tested it.
They would have had to first charge it, then test it, this would have taken
a couple days to include proper rest before testing. But in your case, they
must have charge it and instantly tested it, only the "truly dead" WOULD NOT
pass this kind of a test.
