Question about Avalon PowerExpert PT450M UPS System
Recently My avalon pt-450m failed.when plugged in the lights are all lit correctly and I have 120 vac from the surge side,but nothing from the back up side.any questions comments or suggestions???
Your battery is dead. As with all economy UPS units, these batteries are NiCad technology, meaning a usable life of 2 years average. Due to its weight and disposal issues with dead batteries, your best option is to go with an APC BC or BR series UPS.
