I have a few 440MHz Ultra 10's which have batteries which have finally worn out as that they no longer boot. I have battery replacements, but they are of the same age as the originals, so their lifetimes can't be expected to be extensive.
So I'm asking this list. What are you doing to prolong the life on these vintage machines? Yeah, they're slow & perhaps power-hungry compared to present-day amd64 machines, but I would like to think that there is still usage left -- especially for nominal PostgreSQL use. Any insights/experience shared would be appreciated.
