This should be easy but I'm getting different sources including the repair shop. Can the Deus 1 be left on as ac outlet or will leaving it on drain the battery? Ive always left it connected as long as the battery does not need replaciing. My main problem is with the HFelliptical where if show the battery is fine but has a hard time recogning it. Im inclined to think its a connection problem since the battery show normal and it finally comes up. Almosts always on the elliptical coil.
