 Unfortunately hard disk prices are still high and I'm currently not able to afford two new drives.

 So for now I'm making sure I have a [working backup](2022_06_06_hetzner_storage_box.html) and hope for the best 😅

+## UPS Battery Dead (May 2023)

+To operate the server more safely I bought an [APC Back-UPS 700](https://www.apc.com/de/de/product/BX700U-GR/apc-backups-700-va-230-v-avr-schukoausg%C3%A4nge-batterie-12v-7-0ah-wird-ersetzt-durch-bx750migr/) back when I built it.
185
+Sometime in 2022 I started getting alerts from the APC daemon that the battery needs to be replaced.
186
+So this was after just four years, with the UPS actually running from the battery once for less than two hours.
187
+
188
+As I was getting quite used to ignoring any warnings popping up, I did the same here 😔
189
+
190
+Now yesterday there was a planned electricity outage at my flat.
191
+When power returned, the UPS did not come back online again.
192
+
193
+The outlet that's only surge protected was still working, but the main battery-backed outlets did not work, and the UPS itself did not turn on.
194
+
195
+So I ordered a [replacement battery](https://amzn.to/3MDC43Z) 🔋 and also [two new drives](https://www.galaxus.de/de/s1/product/seagate-ironwolf-10-tb-35-cmr-festplatte-16278068?supplier=2705624). 🖴

+Getting out the old battery 🪫 took a lot of convincing.

+Turns out the battery was very swollen and actually ruptured in multiple places.
208
+Some graphite-looking pieces fell out.
209

210
+So please replace your UPS batteries more often!

+I don't think the charging cuircitry in the UPS is taking good care of healthy battery management...
