This format 9V home supplies musical instruments including an electric acoustic bass that I do not often branch on which amp stack, thus remains in place for very long. Never cast, never lost power despite months "without working!" As to the reliability and durability so absolutely perfect for anything and I would not take the risk of using a low-end cell that may damage electrical circuits flowing.
However, between the Plus Ultra etc, for all battery sizes, colors Duracell should review its code and its data. Obliged to scrutinize each package to try to understand whether this is what I seek. I even in the past, thrown by mistake rechargeable batteries as they looked disposable batteries.
