Old laptops has its built-in UPS degraded in most cases.
- pengaru 4y agoI've never had a UPS not need battery service at some point, and they tend to use lead-acid which is especially fragile when it comes to deep discharges vs. LiIon laptop batteries. I think in any case the battery is a wear item that will need servicing. Just make sure you pick a common laptop with plentiful third-party battery replacement options. Preferably ones that can have the battery swapped while online (not a LiPo pouch buried inside a macbook)
- sentientslug 4y agoNot sure of many modern business class laptops that have hot swappable batteries anymore
- pengaru 4y agoThe whole point of this is to put a disused laptop into server duty.
- gymbeaux 4y agoBut laptop batteries typically last several hours, which most UPSes are meant to last a matter of minutes, so even a 5-year-old laptop battery will likely meet or exceed UPS performance.
