I went into my local Bunnings to get some 1.5V Energizer Max Plus AA (Alkaline) batteries and discovered that the 12 pack is on special when paying. They're usually about $19.
I'm using 1.2V eneloop pro AA batteries for digital multimeters while testing battery chargers but the Bluetooth connections are chewing through them.
Energizer Max Plus seems to have a leak guarantee program (Energizer to replace a damaged device etc).
2023 date was found on the cardboard at the back of the blister pack.
so you'd rather chew through single-use AA batteries instead of rechargeable AAs?
