So I last drove/charged my car Jan2. I was going out of town so I plugged it in before I left on Jan 11 (battery was already fully charged). Jan 20th I get a 12v batt low please plug in message around 4pm I had someone unplug the car put the 12v battery on a charger at 2A. It was initially down to 3.4V. putting the battery on the charger resulted in a flurry of text messages. I don't want to see my international roaming bill for 300+ text messages it generated before I could log into MFM and turn it off!!! The charger errored out and when plugged in again a day later the battery was down to 2.5V!!!!
I get home today and it was still 2.5V Try to charge it at 12A and the charger fluctuates in the 6.5-9.5V range??? Usually the voltage displayed while charging is in the 14-16v range. I let it charge for a couple of hours and I could hear relays and other stuff clicking when it would briefly flirt with 10V. I gave up since I feared damaging my charger. It seemed to be acting like it had nearly a dead short. I pulled the + terminal off and hooked the charger directly to the battery terminals. It started charging on the 2A or 12A setting as normal with indicated charge voltage of 15+. I doubt this will do much since it seems to want to pull more than 12A just sitting there doing nothing? I guess it will go on a flat bed to the dealer for warranty repair. All before I even have plates for it yet!
