    I just retired a Samsung 3500 cell phone (Sprint) for a new Sanyo SCP-4600
    (Sprint). I'd like to avoid paying more for a new desktop charging holster
    and car charger than I did for the entire phone plus wall outlet charger
    ($29.95). The batteries for the old/new phones are different size, but the
    voltages are the same. Both phones charge fully in about 3-4 hours.
    Shouldn't I be able to make a suitable socket adapter -- connecting to the
    two metal contacts at the bottom of the battery -- then connect to my older
    chargers? If there are cautions and formulas to consider, can someone
    suggest those?

    And I wonder if it is time to just *buy* one of those microprocessor
    controlled universal chargers, with the adjustable contacts that can mate
    with any battery. Any experience with those?
