The battery supplied is branded "Malt Max" and has the date 11-2026 printed on it. While AA batteries are readily available, it could cause difficulties in remote areas, and in disaster recovery areas. I suggest it would be prudent to provide a spare AA battery and battery test instructions with the kits. The kit has a manufacturing date of 2021-11-15, Lot SA211111 Use by date 2022-11-12 and bar-code 8 60006 49853 5.
I have reported the problem to the Australian Therapeutic Goods Administration, as well as letting Hough Pharma, and the supermarket know.
