I just purchased some lithiums to use in my self made remote battery holders.

I could find no records of lithiums horribly going wrong of their own accord (user error or game malfunction is a different matter...).

I just figured it would be easier than changing out alkalines every year and half, then sequestering the still good for many things used alkalines until they are used up in toys etc.

NVRAM was the other option, but at $30 a game I figured Lithium + already installed remote packs seemed reasonable.

One less piece of routine pinball maintenance to do.
