I pulled a battery out of this 06R500 that was pretty much dead, only ~3.5yo, good Diehard Platinum AGM unit. Put the charger on it and after a coupla minutes it said SUL. Code means it’s sulfonated and the charger will try for 10hr to deal with it, however it does that. So I guess I’ll see in the morning what the status is. Fairly nice Schumacher charger which appears to have some degree of intelligence built in.
I guess after a battery sits in a car with some dormant load on it the plates or cells or whatever go wonky. I need to learn more about that. Feel free to share wisdom. --FT Sent from iFōn _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
