How to Live-Swap a UPS Battery; Safely

When an uninterruptible power supply (UPS) battery fails, it often triggers a loud, continuous alarm or displays a flashing battery error icon. In an enterprise environment, shutting down the server rack, NAS, or network switch connected to that UPS just to swap a battery means unwanted downtime.

Fortunately, UPS devices such as the APC Back-UPS Pro 1350 (BX1350M) support hot-swapping. This means you can replace the internal battery cartridge without powering down the unit or interrupting the critical equipment plugged into it.

Whether you are an end-user maintaining your workstation or a deployment technician following company infrastructure protocols, use this step-by-step guide to perform a hot-swap safely.
