Help!
I installed new batteries into the UPC (very low voltage output from the two-batteries, roughly 1.3V). After that, I get no response from the UPS. No lights on or flashing, no beeping... nothing.
If I re-install the old batteries (roughly 13v between them), then this constant chirping and green LED flashing continues indefinitely.
Here are two very short YT video that shows the beeping / flashing:

The beeping / flashing is slowing down over time, fyi...
Thank you!
John

With "new" batteries sitting at 1.3 volts you can consider those batteries dead, gone, kaput. Basically that's saying that five of the six cells in the battery are gone totally flat. The UPS would not even be able to consider the "new" batteries installed at that point. Replace the batteries with known good ones.
