That little handle, while a nice idea, would very likely fail an inspection, for the simple reason that you'd need to convince the inspector that the battery sidewall is structurally strong enough to support a 14 lb load (i.e. the battery), without risking spilling gel electrolyte all over you, and dropping the battery on your foot.

Also, the resistance of the battery wires will increase greatly because of the sharp bends—while tidy, they may hinder performance.
