Good order. I used it on a 72Ah battery, the battery was charged in less than 20 hours (I did not stay next door); which is very correct for a charger only 5A. - The big interest: voltage limiter that can charge the battery without damaging it. - Friendly: visualization of the current, which potentially gives an idea about the state of charge (at 0A> charged battery) - Small least: no LED charge / charge termination / power.
