I have the necessity to leave the car unused for long periods... and, as I had installed anti-theft satellite localization wich use power also with car off, I'm worried it will drain the battery...

As I don't like to disconnect battery cables, I tried to use a battery manteiner (original from Porsche, I use it for a Boxter and works well) wich plugs into the lighter socket, with a tiny cable that exits from closed door and connect it to the manteiner plugged in the power.

But... it doesn't works... Thelight on the manteiner don't turn on...

I think it is because The RX-8 give no power under off key's position... Is it right???

And, if yes, there is a way to mantein battery charget without disconnecting cables???

Thanks and sorry for my english...
