| I have an Electrifly PolyCharge charger for my batteries. It takes

It might work, but I wouldn't risk it.
If something says 12 volts, I wouldn't give it more than 14 volts,
since 13.8 volts is about the maximum that it'll see in a car. 16
volts is asking for trouble ...
I've got a 12 volt power supply in my closet. Used to be my mother's.
We used it for testing things like car stereos. Well, we tested a
stereo, and it worked, and then it stopped working. Huh? So we tried
another. It worked, and then it stopped working, and smoke came out ...
... turns out the power supply was putting out about 16 volts if I
Really, I should either figure out what's wrong with it and fix it, or
throw it out. Or at least put a big sticker on it that says PUTS OUT
TOO MUCH VOLTAGE! DO NOT USE! Otherwise, it may eventually eat more
car stereos or something ...

Looks like you did a nice job, but I'd not suggest actually using it
unless you can adjust the voltage on your power supply ...
may be free for you
as well, depending on what sort of spare computer parts you've got
lying around. That won't fry your charger if done right, though it
won't be as nice and portable either.
