I need to replace the battery soldered to the board of my Sinbad, but I'm having a hard time finding what I'm looking for online. Can anyone tell me what I'm looking for and where to find it?

--->External battery pack .

You can buy those button cell or lithium batteries as original with the solder tabs (we use them at work on some things) but your best bet is like mentioned above. Just put in an external AA 3 cell pack. The diode isn't necessary but does provide protection if you put the batteries in the wrong way.

That's what I'll do. I actually have on of those sitting around.

Okay, I put the battery pack in, but it didn't do anything. Now that I'm looking closer at the board however, I'm seeing two separate slots for the + and - leads. I soldered the leads into the same slots the previous battery was attached to, but could they be in the wrong spot?

In the picture you can see the two unused slots above the ones I'm using.

From what I see in the pic it's hooked up ok as the positive lead is connected to the hole above it with a trace .. and the ground is on the larger width ground trace behind.

You might have an issue not related .. I'd suggest measuring the battery voltage at the pins of the 5101 ram and see if it's there with the machine turned off ... if so .. keep troubleshooting... (I'm guessing Sinbad uses the old 5101 ram .. it's late and kids are screaming).

Did you use a diode in the 4th battery position in the battery holder? If you did, is it oriented correctly?
Do you have a meter?
Measure for 4.5 VDC at the leads you soldered, + at Red, - at black. If you do have 4.5VDC, do what Brokedad suggested and measure the battery voltage at the pins of the 5101 ram, pin22 for +, pin 8 for - (ground). If not recheck the battery holder circuit.
