Could I use one of these connected to a 12volt lead acid battery to run my Arduino UNO? so I don't bypass the internal regulator.
That's just a bit of wire, no more, no less.
Why would you not want to bypass the internal regulator (which itself wastes more current than the MCU does in sleep mode)? If you want to run from a 12V (14V) battery, you really should use a 5V switchmode regulator designed for automotive input voltages.
