I'm no expert but I wouldn't try that: I think battery chargers adjust the current flow to battery as it charges. The regulated power supply mentioned has a steady flow of current out (regulated) doesn't it? I would expect the battery to be damaged by charging with a power supply.
LM317 can be used for regulated dc power supply upto 37V. For more voltage range, a zener can be connected at the reference pin.
