The battery in my 2012 is not holding a charge. If I leave it parked for couple of days it dies and I need to put a charger on it. I installed a battery tender to keep the charge up while at home since I don't drive the Expy a lot but it still doesn't want to hold a charge. I took it to Advance for testing and they said the battery is good. I've done my own charge tests and parasitic drain tests. No identified draw over .5 amps after putting the car to sleep using FordTekMakULoco's procedure. Here's what I get after running three battery tests at home:
Testing with engine running (mimic's the Advance Auto test):
Test immediately after turning engine off:
Test after sitting for an hour:
Battery from Advance purchased Feb 2022:
The state of health immediately drops from 100% to 78% which leads me to think the battery's going bad. I've tested the alternator and the system's putting out 13.8v so that's good. I've charged it overnight with my 10a charger and I still get a "Good - Recharge" reading when I test it.
I'm taking a trip to FL in two weeks and don't want to get stranded with a bad battery. Any recommendations for replacement? I was leaning back to Advance for the prorated warranty but I'm thinking they kept the same bad Die Hard quality Sears was famous for in the 1970s!
