Robin,
I looked at that, but with the Air con pipework, the screen wash pipework and the headlight cover in close proximity, with mild vibration, you stand a very good chance of chafing damage to either or several components.
If you are getting short of room adjacent to the battery, then reverse the bracket and drop the can lower. It will be easily accessible for emptying and further maintenance. With the right OEM clips it will be virtually OEM style too.
