The UB may come with a variety of battery terminals, including marine, but that does not make it a deep cycle. Look at the brochure from the UPGI group, and you'll see deep-cycling limited to about 300 cycles:
On the other hand, look at the very bottom of the line from Trojan - at least twice or much more depending on model:
Since 1925 Trojan Battery Company been a leading manufacturer of deep-cycle flooded, AGM, and gel batteries as well as our new Trojan AES and lithium-ion batteries.
Now THESE are for when you advance beyond the typical learner / hybrid battery.Comment

So, my suggestion is for the big box store, marine deep cycle battery, size Group24 or Group27, whatever you can find and is cheap. It's going to most likely die of old age, not cycles, if you are only using on weekends or SHTF usage.
A 100w panel will service it, but not if you run a lot of daytime battery charging or Ham radio usage, that will subtract from the recharge amps, and you may end up in the hole after a couple days of heavy usage. Having a 2nd panel you can bring into service would be handy, or use your car alternator to boost up the battery for 20 minutes.Comment
