The replacement 4 pack showed up today. Each of the 4 cells measures 3.56V. So not dead and no bad cell. I plan to swap out the entire pack, even though only 1 of the cells in my vehicle pack is lagging significantly, and one other is a bit behind.So now about the charging. I am hesitating to hook up my Noco Genius 3500 even though it says Li-Ion, as it also says 12V Li Ion. I didn't know there was such a thing. Maybe a 3 cell battery? I can't measure what it puts out because when you turn it on and put a voltmeter across it, the voltage varies as it appears to be probing the load to figure out what it is. I don't see how hooking it up could do any harm, if it doesn't put out enough voltage to charge anything?When I look up the specs of the charger, it seems to put out 14.4V when in Li Ion mode. That's not enoughThere is a "repair" mode which puts out 16.5V 1.5A and it then acts as a "DC Power Supply". Someone said put a "small resistor" in series .. how small, and what does this accomplish? (I guess it reduces the voltage when the current is high, and then the voltage rises as the current decreases??) Is a vice grip a good enough resistor?
