Servus together, I changed my battery a few days ago in my Focus MK3.5 because the old weakened. Due to the dimensions only one EFB battery fits in with me (is also required wg. start-stop and the charging management / recuperation ). Now my knowledge the EFB batteries in full charging condition actually have a maximum 12.7 volts. I have my Exide EL752 with my Ctek charger fully charged and have after about 12 hours still 13.0 volts rest voltage and even after 12,9 volts of resting voltage over 24 hours. How can you classify that? Especially “good” battery or what doesn’t fit?
