Thanks in advance for any help.
I doubt that they are still in production, as I haven't seen them in over 10 years. Plus, technology has progressed rapidly over that time and you would probably be better off getting a simple PWM controller with 3-stage charging and temperature compensation like the Morningstar Sunsaver-10 for around $50.
