voltage (which
for lead acid antimony
batteries is at 11.89 V, but the
battery can in theory be at any
voltage between 0V and 11.89 V and it is in any case approximately empty), and has 48 Ah capacity, a 1.25 A charger will fully charge the
battery in approximately 38.4 hours (just divide the Ah of the
battery by the amperes of the charger), but I would add few hours more because the end of the charging occurs at constant
voltage, not at constant current.
