Searching for good deals on AAA battery for alarm clock, flashlight, alarm, etc. Some of the things are emergency items, so just tuck the battery in and will never use the devices (touch wood).
Not gonna use it for toys or motorized item as I don't have any.
Does buying the cheapest rechargeable AA/AAA for this purpose even make sense? If yes, what model (battery/cell) do you recommend?
Share your best loot.

Sample/reference:


This DoublePow    rechargeable cell reliable? Lots of sale on shopee. I can put my super old GP Rapid PowerBank charger to good use.
