As part of my CentOS-to-Ubuntu system migration struggles, I also repaired my UPS (Uninterruptable Power Supply). The ancient 12V/7Ah SLA (Sealed Lead Acid) battery gave up the ghost years ago. While I am "under the hood", I will add UPS interface software to my desktop systems, so I need to get the UPS working again.
Rather than spend $20 on a replacement SLA, I purchased a form-factor-compatible 12V/8Ah LiFePOâ‚„ battery for $40. Slightly more capacity, no liquid, no acid, no toxics, and a third of the weight. Internal electronic battery management system. In theory, it can last decades, outlasting a dozen SLA batteries. Charging the new UPS battery now. I will shut down the computers and add it to the power circuit Real Soon Now. Keith -- Keith Lofstrom [email protected]
