I use it for wireless mouse. Because it is a specification of two AA batteries, it feels slightly less fatigue feeling with a slightly lighter manganese dry battery compared to an alkaline dry cell, and it may be suitable for work like a mouse because it is a structure that does not leak easily. . It is worse than alkaline dry batteries (although alkaline dry batteries had a year in dry cell batteries, they had only three months with manganese dry batteries), but price and lightness are attractive.
When manganese batteries are not used, it is said that the electromotive force recovers, depending on the application, it seems better than alkaline batteries. However, I do not really understand how to actually use it.
