You bought the unit I had bookmarked! Good to know there's another one still for sale. I'm a bit turned off by the fact that no accessories are included, not even a battery or power adaptor. The shipping details from Keysight are also very vague, which courier? Who does the customs clearance?
I did message Keysight about the battery in the unit you just bought, the reply I got:
"thanks for your message. It should be included but I don't see a comment in the inspection field. So lets assume the battery is not included. If it is it will be a nice surprise for you. Best reg. Oliver"
I just recommend getting a universal charger, that have adjustable voltages in steps (of, usually 12, 15, 17, 19V). They also come with an assortment of DC barrel connectors (meant for most laptops). Quick example of what I mean:

Might have to crack it open to double-check the polarity, or find a high-res picture of the U1574A online so you can see the marking.
The battery replacement might be trickier.. (I'd say, just buy an original one - even at $160)
