Does anyone know why the hybrid 12 volt battery is engineered to only charge to 80 per cent ...... I think that a lot of the problems could be solved with a 95 or 100 per cent....
I use my 1 amp desulfating charger on my AGM battery about every month.....it usually takes about 24 to 72 hours for a complete operation....but again I use a 1 amp charger.... i believe that a slow charge is the best way to go if you can do without the vehicle for a few days...
12 volt battery is not being charged fully....I do not know why it is engineered that way.... I have to desulfate battery with the charger/ desulfator every month...good luck
I to went through 3 batteries.... insist on an AGM BATTERY....this took care of all my battery problems....I also use the battery maintainer/ desulfator every month......good luck
Battery voltage is not the only thing that controls the cabin lights etc....many times my cabin lights would not come on when battery voltage was 12.6 volts....
After 2 1/2 years with AGM battery, I have learned that desulfating is necessary to keep the 12v battery working on my 23 hybrid.....I learned the hard way....in summer once every month.....in cold weather l do it weekly......good luck....
