I'm replacing the batter in a Game Boy Advance game cartridge.
(Don't mind the bad solder job; the iron isn't handling well.)
I've gotten it to work, but the battery is held down with very little force; so I don't have much confidence in the actual connection between the bottom pad and the positive-side of the battery. I feel like one bad shake and the battery might (even if momentarily) disconnect on the bottom side.
I tried shaping the bottom pad using some small pliers, but that clearly wasn't enough. Does anyone else have any ideas on how to make a more solid connection on the bottom side?
I have electrical tape, pliers, soldering iron, and even some solder tabs.
Here's a different angle, in case it helps:
Here, the pad and battery only touch at a single point. It's slightly better when there is pressure pushing the battery down.
- NOTE: If anyone feels this belongs in a different site, please feel free to move it.

Batteries are often spot welded.
How about buying a battery with the tabs?
