Im in my second season with my Beta 38, WOC K35616. All is generally well, but I have definitely experienced significant battery bank degradation since the Beta was installed and I do not believe that my very conservative use has changed or that that the batteries have naturally worn out. Having checked most things, I believe that the charging voltage from the standard alternator/regulator is too low to ever fully charge the batteries. I understand that this stock regulator is not a smart one, but is there any way for me to change the set point?

Weve just been out on a two-week cruise, which included a few long motoring days that should have fully or nearly fully charged the batteries. Watching my meter, I see the charge current drop off and the voltage increase as expected after the engines runs a bit. But once the charge rate is very low, a tenth or two of an amp, the voltage never gets above about 13.85 volts. Though OK for a float charge, my Odyssey AGMs really want a cyclic charge in the 14.4-14.8 volt range, so they are likely never being fully restored.

The best answer is probably a Balmar or other smart regulator. In the interim, is there anything g Ican do to make the standard regulator installed run at a higher voltage? My solar panel and controller will take care of the long-term float charging, but I need the alternator to do the bulk cyclic charging.
