APC BE400-UK - BACK-UPS ES 400VA 230V No battery Boxed. Powers up but continuous beep from faulty battery (not included). May have other issues because occasionally it would start beeping for no reason I could find and need rebooting. Hence sold as spares or repairs. I had it in use until the battery seemed to fail and decided to buy a higher rated APC instead of new battery.
