New doesn't=good. Babies die! A generic "old school load tester" will not put enough of a load on a battery that size to give you accurate results. Most of them are good for about 200 amps. I'm not saying I'm convinced your barrery is bad, but your numbers are telling me something's not right with the battery, or the amp readings aren't accurate. I just want you to be sure before spending money on the wrong part. You'll still need to repalace the ofending part whether you get it right the first time or not.
I owned an auto electric business for over 20 yrs and somethings not adding up.
To properly test the battery it needs to be
fully charged, then let it cool for about 1 hr before load testing.
