I just had to pass along kudos to [APC][]. I use one of their BackUPS battery backup systems. It’s been flawless for most of the past 3 years. In the past 3 days the overload light has tripped and it shuts off power to everything. Not what you want.
I called tech support. They picked up the phone after only 2-3 rings, ran me through some diagnostics, told me there was probably 18 days left on my warranty. Then they told me they were shipping me a new unit.
They are my customer service heroes.
