Re: New Balmar SmartGuage experience
I went through the day yesterday, in normal fashion. I left her plugged in, charger on and used 12v appliance as usual: lights, stereo, etc. As stated, I woke up, with the charger on Full, zero amp output, batteries at 13.1v and the SG said 100%! Overnight, the only thing that would have drawn 12v would be the fridges, but it was cold and doubt they cycled much.
As the morning wore on, the charger remained on Full, while voltage began to drop slowly to 12.9, then 12.8. At some point, not long after 12.8v, the charger comes back on in Float mode? It stays on for a couple of hours and returns to Full. The Smartguage now reads 91%.
My head is spinning.
