It would be a much better idea to phase it in giving BRCA members a season or two which would enable them to exhaust their existing batteries. Once they are exhausted they can then purchase the batteries on the list.
This would create very little financial impact and reduce the environmental impact of thousands of perfectly good batteries being thrown away.
This would be a much more responsible way of switching over to the new battery ruling,
Maybe as our rep you could put this forward to them Martin.
