I'm looking at a battery replacement for my '84 E-28. Current bank are (2)Group 27 flooded dual purpose batteries. At least one seems to have trouble keeping charge and it's date is 2003.
West Marine has Group 27 AGMs on sale for $200. Anybody have experiences (good or bad) with these batteries?
Also, with AGMs in general, what are experiences when doing a direct swap from flooded and charging only on the alternator? I have the OEM alternator. Not sure what the output voltage is. Still on the hard so can't fire up and check.
Don't want to have to invest in a sophisticated alternator regulator. If my output is the typical 14.4 - 14.8 V will they give me the expected longer life for AGMs?
Would love Lifetime batteries, but they cost twice as much and only have deep cycle, not dual purpose.
