Sounds like (maybe) two issues. (1) Bent contacts: As far as the bent metal clips are concerned, try using needle nose plyers to orient them correctly (bend them back). If this is part of the upper set, they are one piece that should be able to be removed by just a flat blade screwdriver and/ or needle nose plyers. Once removed, it might be easier to shape/bend back in place. If the lower set is bent, then you might consider removing the back case to access the metal connectors better. (2) Not powering on: If batteries can be held in place temporary to make good contact and the wii remote does not power on it may be more serious and requiring you to open up the remote to inspect. A few hints in either case: (1) Corrosion from battery leakage can be a problem and if so, would need to be cleaned out completely. Corrosion is usually visible on the upper metal plate as a dry green/white powdery substance stuck to the metal plate. Cleaning toughly with vinegar and baking soda, will help and may result in fixing...
