Remote Battery holder or NVRAM.
I had similar issues with Duracell. Never seen it with any other brand so quickly. I now use "Varta" if I have to use conventional memory. I use these because most container pins have this brand installed, and to date, I've not seen one single Varta leak. Even though the batteries may have been in the machine for years - and they are flat. They are also VERY cheap, but so far, not nasty !
