I know that many people tend to disregard older versions of lenses because they're less sharp or have fewer features, but that usually means that I can get them for a good price, now. I'll rue the day that I can no longer find batteries for my 5D III.
It's going to be a LONG time before there aren't batteries available for a 5D III. You can still get replacement BP-511's today from third party makers, and the last camera that used that battery was the 50D in 2008. Considering the LP-E6 form factor is still used today on cameras like the R5 II and R6 III, and even the latest LP-E6P is compatible with the 5D III, I would imagine you'll be able to get LP-E6 batteries, new, for at least another 15-20 years, and likely longer. There are SO many cameras that use that battery (Every 5D from the 5D II, every XXD from the 60D through the 90D, The 6D and 7D cameras, every R6 and R5 series mirrorless body and the R7...26 total cameras) that they'll be making replacements for ages.
