After reviews of past posts on RFI reflector for RFI free UPS units, I've
narrowed down possible replacement for my old discontinued APC Back-UPS 650
which has been fairly clean for me in the RFI category but has a dead
battery.

Wonder if anyone has tried the following Tripp Lite Standby UPS models
recently?
Looking at either ECO series, ECO750UPSTAA (TAA compliant);

ving-standby-ups-usb-port-12-outlets~ECO750UPSTAA
or the Internet Office series, Internet650U1 for a replacement UPS.

I noticed the Tripp Lite units both weigh much less than the old APC unit
which probably means switch mode power supply for the charger/inverter or
smaller battery or both. APC weight is 14.33lbs vs. 7.22lbs (ECO) and
3.96lbs (Internet).
I've seen RFI posts saying the Internet UPS was clean in the ham shack, but
those posts were some years ago so it may've had a power supply design
change making it noisy today.
The ECO model stresses all outlets are "Noise Protected Outlets", but that
does not mean RFI free on HF.
Or should I just order the APC replacement battery cartridge for $45 and
keep the clean UPS? Perhaps both JIC?
Thanks for any advice or suggestions.
