Look at the back of it, there's a red and black plastic connector on
the back panel, intended for attaching an expansion battery pack

This looks like the same connector...

Thank you! I knew someone would know if I could just find a good enough
picture.

I agree that it looks like a Powerpole connector. There are several
differant sizes of them. Often a connector for the positive and another for
the negative and you use a small pin to connect them together.

You are talking about 12 volt devices, doesn't that connector have 24
volts on it ?

Inverters are often ran on other than 12 volts.



Dangit you're right!

I was getting the Tripp-Lite unit confused with the last one I replaced
the battery in... which was an old APC unit with a single typical 12V
7AH security battery... the TL unit uses TWO batteries... and sure
enough they're in series! And the other two UPSes that I still have
also use two batteries as well, I gave the old one to a friend of mine a
while back.

Well there goes a perfectly good idea.

I do have a 12VDC benchtop power supply as well as a CTEK battery
charger with a "power supply" mode so it's not like I can't make my
stuff work. I was just thinking that since the UPS was powered up all
the time anyway I could avoid adding any more transformer losses to the
power bill... but c'est la vie
