Maybe our resident EE @Rick Christopherson can give us some insite on all this voltage amperage temperature timing stuff ?  [unsure]

Actually, to answer your question, yes, different battery technologies require different charging profiles. That's the reason why intelligent chargers utilize microprocessor control. It is no longer just a matter of giving a battery a voltage above discharge in order to charge. Each battery chemistry requires a specific charging profile as it passes from dead, half dead, half charged, to charged.

Depending on the battery type, some charging phases are based on voltage, then the next phase is based on a specific amount of amperage injection, and so on, until that particular battery type reaches full charge. It is no longer just giving it juice until the battery is charged. [cool]
