Is it worth changing http external backlinks to https?

[ChristianRdz]

A client's website is fully secure (https) but I noticed some backlinks are still pointing to the http version of the site. Those links redirect just fine so we aren't losing any traffic, my question is should I try and get those changed with that webmaster? Is there significant SEO value there?

At one time a 301 redirect was reported as loosing 10%-15% of link authority, then Google more recently said nothing would be lost. 301 Redirects Rules Change: What You Need to Know for SEO Personally I would update any links on my own website and moving forward make sure I was referencing the new https url. I would not bother getting old external links fixed unless it was really easy to do so.
