If you still want them let me know. You can come by and look at them if you want. I opened the one I'm keeping, but the other 2 are still in their package.
Yes, they use 2 "D" cell batteries and I think they last 1-2 days. Mine lasted at least 1 day. That is all I needed it for.

CORRECT, when you put the extra battery in they run in parallel and you get around 2 days on two duracells.

Another low-cost option: I had the air hose from my Penn-Plax battery air pump feeding into the base of a small, 12w powerhead. The powerhead was attached to a 750va UPS. The powerhead fractionated the air, keeping the DO high for many hours. It would run for about 10 hours on the UPS.
This was a budget set-up; UPSs like this can be Ebayed with new battery for about $60.
It's also an automatic system; everything turns on even if the power fails while you're gone.
