Your comment about the battery is noted. I have some more arriving this week, and can't wait to compare.
Dennis, thank you for your reply, and your links. That generator looks way cool[!], as do the server power supplies. I never realised how many choices there were in this field! I'm off to do some more reading.
Thanks again, guys - I appreciate you taking time out to help a noob...
Or, if you want to buy brand new with a two year warranty, check out this Jameco unit. Jameco has been around for decades and will sell to anyone with a credit card. These units are designed to operate 24 hours a day, 365 days a year.
The Jameco Meanwell power supply has simple terminal screw connections. (The AC input requires three wires, hot, neutral, mechanical ground, and, isolated 12 Volts DC output, with three screw connections for 12 Volt negative, and three more screw connections for 12 Volt positive.) Meanwell is a major supplier of these type power supplies.
If you have any small children around, you'll need to cover the 120 VAC terminals with some short of non-metalic shield.
3 AM? you stay up later than I do!
