I have a dna 40 chip I had to unsolder both the pos and neg battery wires along with the USB wires which are right next to each other. I noticed solder connected between the + holes of the battery and usb wires as well as the - wires. I've tried everything I could think of to separate the solder but nothing seems to work. How can I c lean off all the old solder leaving the space required between the soldering points?

Those are the same contact actually, the holes have the same traces on the board. No need to separate them.

I'm not familiar with the DNA40 wiring, but to clean up solder you need solder wick, which is pretty much just a flat braid of fine copper wire. Just use a bunch of flux on the wick, put it over the spot, apply heat and just about all of the excess solder will wick right up into it. Be very careful not to drag the braid across the piece but to dab it, dragging it can shift or outright lift the pads you're trying to clean. Then just wipe a little cleaner over the flux gunk (MG Chemicals 4140 pen works well enough) give it a little scrub with something like a toothbrush and wipe off with a paper towel and you're good to go.
The reason I want to see pics is, if you are talking about crossing the bat and charger contacts, that's no real issue, they are common on each side
