You need a dumb charger, I can't remember the brand that I have, I bought it around 2003 or so, it'll shove electrons out no matter what, if theres a lot of resistance those electrons won't go anywhere but its at least trying to put them out... I'm curious why you tried 2a though, after 3 hours thats 6ah which is doodly-squat, you group 49 is something like 70ah so if it was totally dead you'd have gotten less than 10% into it. At 10a you'd be closer to half... -Curt

I figured I could give her a jump with Polei, being diesel to diesel, but all I got after five minutes of electrons flowing over what now seems to be overly fine wire gauge (maybe I need to invest in 00) was a wincing shrug of an attempt by the starter. Screw it, I had Polei running, so I took her. I got home post game and tossed the sears charger (smart 2/10/50) at 2amp at the battery. I just installed the group 49 in June, battery born 4/18, so was bewildered that the battery was non responsive. Three hours of two amps made no impact on the battery, so I popped it to 50 amp start mode and gave it a chance to put some electrons back in the box. No avail. No action at all from a turn of the key. And, the charger was pretty warm, it was getting dark, and I was not interested in messing about with electrons in the rain. The charger and battery came inside and I put it to charge low and slow over night. No electrons in the box this morning and just a warm charger. Multimeter found 2.8v in the battery and no voltage from the charger. This forced me to unhook the battery tender widget from the R107 and put the battery on that. The Diehard charger just moans and gets warm with no lights or needle action, nor expulsion of electrons out the clamps. I have the receipt for the battery, and will visit the vendor if she does not take a charge. What I would like is the group consensus on replacement charger for my gaggle of group 49 batteries. All are fairly new (under 18 months). I am tempted to get a wheeled charger with ability to jump a cold winter battery at this point. Or, should I get a standard Schumacher set up for $75 with low and high amp? What of a few of the low cost things and just keep them under the hood of each car? clay monroe redgh...@comcast.net _______________________________________ 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 _______________________________________ 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
