I found these batteries a couple of weeks ago selling at Daiso as the batts in my daughter's musical rocker ran out.
I've heard of alkaline, NiMH, NiCd, ZnC, Lithium etc but not Manganese batteries though.
So being curious, I bought a set (it came with 3 batteries - not something that you see everyday) to try them out.
I did a search on Google and found this on a Panasonic website:
"Manganese Battery is ideal for devices that require a small and continuous supply of power such as clocks, remote controls and radio cassette recorder. Manganese Battery is an essential item for most people around the world with the increase of battery-operated devices."
So far, they're still powering the rocker so I guess the above statement holds.
