A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I have 2 UPS' that have expired batteries. The manufacturers want crazy amounts of money to replace them, and a friend recommended I look online to see if I can get them elsewhere. However, the sites all seem so sketchy. Have any of you had good luck with third party battery sites? Obviously a bit nervous about safety.

I've used local supplier for years who has spesifically selection for UPS batteries. Even APC ones tend to be pretty standard, just rip the APC stickers off and get the actual battery model number and ask from your local shop for replacement. I got a pair for new-for-me UPS a few weeks ago. Official APC kit would've been several hundred euros, the ones I got were ~50 with postage. They might not last quite as long as 'brand name' ones and power output is a slightly lower even on spec sheet, but that unit is running at around 15% load anyways, so in my case it doesn't really matter.
