Use for old lifepo4 cell phone batteries?
 

.

I would, if I had any, use them in small electronic projects.

You couldn't use them as a starter battery.

Also, awesome, you use Windows XP still too? :)
Me too, I'm getting great use out of this Laptop made in 2006 by using Windows XP and most apps that I need to use are all 32bit.

Those are Li-Ion by the way, not LiFePO4. If they were stored empty they probably are gone anyway.
