Input Amps isnt an indication of power output of the battery. Only the mah you get on discharge is a reliable indication of the battery's condition.
When charging, the reading your charger gives is just a mathematical equation of the charge rate multiplied by the time the battery was charged for. When you discharge the battery on a decent charger discharger it will record the correct figure.
