Vivitar Charge 15 photography charger for NiCad NC-3 battery packs

Vivitar Charge 15 charger for photography batteries, still with the original box. This is for charging Vivitar NC-3 NiCad battery packs. There is the original battery pack included, but it looks like the battery cells have been leaking (there are crystals around the ends of a couple of them). so we are selling this as just the charger.

The box is worn, torn and has been repaired with tape.
