The thing that slides has the same exact technology as any other charger. The reason for the individualized chargers is to make the batteries exclusive to a brand. What's inside the charger is just a wall wart of one shape or another. The port for the battery is what makes it a match to that company's battery. You've got two dead ones... break one open and get the specs off the label of the transformer inside. You could replace both of the insides for very little. I have one transformer/wall wart/charger that came with a dial to select voltage, and sixteen plugs to choose from. It matches everything in terms of spec, but you still need the B&W plastic to engage the battery, so save that and the contacts.
