Looks OK, but it is quite cheap. Personally, I would go with a known brand, something like Yuasa or Varta.
I have Yuasa on the boat. All 7 of them. They have been good.
Their electrolyte impregnated mat motorbike batteries don't like going flat, it kills them stone dead.
Mine aren't impregnated mat. But no battery much likes going flat. Doubt if any of mine have ever been below 50% charge.
theres no guarantee either
if you look at, for example...

you get a 4 year guarantee
Same issue with an eBay seller?
My limited experience with their batteries, they don't always seem to look after them and don't know what a new, healthy battery should look like. While i hope that's not usual, i won't buy a battery from them again
If you buy cheap, you will probably end up buying twice. As you say, it will likely be tested by a Disco.
Cheap vs good value doesn't always work out the same
Second that, I've got on as recommended on here, cannot complain.theres no guarantee either
if you look at, for example...

I had exactly that problem and got around it by rerouting the standard earth, so should be OK.
