I want to share some of the advantages of the Vympel 57 charger, which I found out for a short time during operation. A very important feature is the ability, at certain values of the charging current and voltage, to desulfate the plates and restore the capacity of the batteries. Thus, the batteries were restored: car 12V, 65A/h, from a sprayer 12V, 8A/h, from a cordless screwdriver 14.4V, 2.5 A/h.
