Cheap Batteries
I bought some AAA batteries, $2 for a pack of 24. At that price you just know they have to suck.
Check out the colour scheme. We wouldn’t be trying to imitate a well known battery brand here by any chance ?
And look! they even have a fake battery tester strip. It’s just printed on the side.
And no, they did not last very long. I don’t think they are even alkalines.
