How to fix a CR2600 Wireless Scan Gun that won't charge.

Been trying to fix these at work when I see them. Now, they seem to be broken everywhere. Why? Too many folks bleaching them with Clorox Wipes (and oxidizing the contacts in doing so). I showed my coworker, Jon, yesterday how I fixed them. He was impressed, and relieved (as he was charging it by weighing it down with an IV Bag). So today, we found another and here is my fix, and I'm sharing it with everyone.
