hello everyone, im new here, and desperately want to get it right!
i'm making a charger for a 2.3A SLA battery, and so far, i found a decent schem. for a constant voltage charger. it charges at 650mAh, and thats a bit over the 1/10C rating!
i would idealy need 230mAh. i cannot use a transformer smaller than 2A, as this is part of a circuit that operates a credit card machine, and the battery will be used as a backup only during a power failure. could i add a constant current circuit to this, or just add a series resistor?
if so, what value?
Thanks in advance
