19 rebel 5.7 e torque purchased Dec of 18. 26000 miles. I left it sitting in below freezing temps for 4 days. Went to remote start and no flash of the lights nothing. Got in hit the start and tried but nothing. put a jump pack on it and got it to start. I thought ok. Far enough. Pulled it up to the garage and put my charger on at 30 amps. The charge will kick down to 2 amps when full. Checked on it several times after hours of charging it never dropped to the 2amp setting. Hmmm. Disconnect the charger check it with a meter. 12.6 volts. Started the truck no problem. Let it run a minute, shut it off put my tester on it. 90% charge 650 cranking amps. Checks bad for high resistance. I forgot I was a member of this forum and started checking for a battery on line. Settled for A diehard AGM h7. My truck has never been anywhere other than the dealer and I wasn't going to allow them to do it. I decided to take the battery with me for the core charge and do it myself. I pull the battery and the bottom of the tray was filled with half frozen acid. I'm glad it didn't have any drain holes in it. I soak everything up with shop tiles and rinse it three times and dry it all out. Take to the advance auto and the guy says do you need that tested ? No its my core charge. He says I will sell you a battery but we should at least check it. Has his coworker check it and says its a good battery it's just low on charge. I need a new battery. Let me look it up. I have it here on my phone. This is the one I want . Bring it home, test it , a little low from sitting on the shelf, top up the charge, install it and start up. Voltage in dash 14.7. I let it warm up a little and start turning things on. Heated seats and wheel. rear window defrost, mirror defrost and drops to 14.6 at Idle. Next day go out start it , check engine light is gone. Had to re pair my phone and put my radio presets back in. So far so good. Nuff said.
