Do I really need an auto cut off circuit for my battery when my charger only outputs 13V and 1A at max. The battery I want to charge is a 12V 7Ah Sealed Lead Acid. I heard that the cut off for lead acid battery is at 13.7V, so it should be fine right?
I also want to know if I don't use a cut off circuit can I leave the battery for charging overnight.
And in case I need an auto cut off circuit the would any one suggest one that has both upper and lower threshold i.e cuts off at 13V and powers back on 11.5V etc.
