I did one too and this is ALL that I found? Is this it? You will need to look down the web page a little bit to find it.

Funny thing about it is there is a $0.00 price? Maybe you can call this "Ward Electronics" and ask.
When our 12v rechargeable failed that came with the rig, we went to a hardware store and bought a new 110v rechargeable. This way it only recharged when plugged in to shore power (like when stored at home). It also does not run down the house batteries over time and is documented to last 6-8 hours on a single charge!
On edit: I used "audiovox avf-1 flashlight" in the brower's search field and got a lot more links listed for it. Don't forget the quotes!
Good luck!
