I was presented an opportunity test this out at a discount so i confirmed i could provide all types of feedback positivenegativeall in between and since that was the case i was happy to try them out

these are already charged up when they arrive so no need to charge firsti wanted these for low drain devices tv remotes computer mice xboxps4 etc controllers and clocks

Here is what i foundthese seem like any other pack of aa batteries until you open them up and see a small charging port on the side
