The first thing I would do is check the voltage provided by the charger - both at the charger and at the battery. What is the difference between those - voltage drop in the existing wires? If significant, it is worth checking the drop in connectors and cleaning up the contacts on one that drops more than a tenth of a volt.
I have a portable smart battery charger that charges a half discharged battery at over 15 volts in cold weather, pushing way more current into it than dumb chargers. Someone wrote in these pages that battery manufacturers have increased their recommended charging voltage to 14.8. Likely the problem with your old charger was that it was providing only 13.6 volts.
