I'v got a question?

First let me start by saying,I live in the boondocks! I also love reptiles.Until recently I resisted the urge to venture past my turtles.The prime reason behind this is our ever present threat of power outages.This past winter we dealt without power for a few weeks off and on.Not a big deal for hibernating turtles.However,I recently acquired a baby Savannah monitor and have grown rather found of this little monster. In order to keep him healthy and happy I need to start preparing for the inevitable.I need any input I can get from members with a similar situation.What kind of inverter do you use.What type of battery will give me the most run time between charging and so on...

Winter will be here shortly and I need to have the proper frame work in place any input would be greatly appreciated.

Thanks,Mike
