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.
I'd prefer not to. But the Bluetooth connection is being a bit unreliable after measuring the voltage and current of a charger for 3 hours. It cuts out toward the end and then I have to restart the test.
2x 1.2V NiMH isn't quite cutting it for these digital multimeters with Bluetooth.
I'll try to modify the multimeter to accept DC input from the wall later. But for now, I want to get through a few dozen tests to complete two battery charger reviews by mid-March.
