Aquaseal works on just about anything involving leaks like bladder/wader related for a permanent repair. It works where you can't use a patch like the seams of a bladder, which are near the edge. I use a toothpick to push some of the gel onto the inside surface of the bladder, so that it forms a mechanical plug from inside to outside surface. The plug is much stronger than just a surface patch, as the inside head is impossible to push out. Keep it away from gluing to other inside sections by slightly inflating the bladder. For longer tears you would need a patch similar to the bladder type material you have with your tube. There is also a UV version for quick repairs on location, but it is not as strong. Tiny pinhole leaks away from the seam can be stopped with good quality vinyl electrical tape for an instant repair.
On the battery you can use a much smaller U1 size deep discharge available from Academy for about $50. Very large gel UPS batteries used for computer backup will also work and they are replaced at regular intervals by most businesses- might be available at low cost/free used in some cities. Gels must be charged slowly with very small chargers, so they fill very slowly over 12 hours or so.
