Battery charging and One Control monitor
Bought two new deep cycle batteries for my Forester. Batteries on One Control tablet monitor show charge after 3 days plugged in somewhere between 12.3 at 70% to 12.4 at 80%. Battery level charge never gets to 12.6 which is 100% charge. Is the One Control reading of voltage accurate?
I have gotten closer to 12.6 if I use an external 30 amp charger but don't understand why the Progressive charger never gets a higher charge after 3 days plugged in. Any thoughts or experience? Thanks.
