Winch battery problem was created by Mraz
I finally fitted the control box and wired my winch so I tought I'd gove it a try. And bummer, it worked fine for a minute or so and then car almost died when spooling the wire back on the drum. My battery is tiny and weak and old (45Ah, 330Amps). So my question is, what's the biggest battery one can fit in place of original one without too much "improvisation". Would a regular 55-60Ah battery (500-550 Amps) be OK for ocassional winching or should I look at Exide Maxxima?

Really depends on your budget.

But a decent quality agm battery with 700+ cca is preferable.

The are better options than the Exide Maxxima. Like odyssey or optima. Or perhaps a Varta AGM. Numax if on a budget.

If you want a good winching battery that doesn't take up a lot of space, an Optima red top is great :)

Would this work?

eshop.wurth.sk/Product-categories/Starte...3143.cgid/en/US/EUR/

There's a 40% discount on batteries in a nera-by shop and this looks I could somehow fit. I assume it being a D+ is not that big of a problem.

IF you decide to purchase the Optima battery..... the red top is a rough use battery designed for Off Roading; the yellow top is a deep cycle battery better suited for winching.

Optima Red
Optima Yellow

Not exactly.

The red top battery is a starter battery, suitable for most vehicles. But especially big diesels that require lots of amps to crank the engine. Nothing special about it other than lots of CCA's compared to its size.

The Yellow top is correctly a deep cycle battery which is good for many things that draws amps over time. That's not exactly what a winch does even though many use yellow tops for winching, myself included.

But I've seen tests where the red top performs better winching than a yellow top does.
And a winch motor is more or less just a big starter motor.

A couple of things worth mentioning regarding Optima red vs yellow. The yellow top Optima's I have are the big tall 75 Ah/ 975 CCA ones, quite bigger than the 50 Ah/ 850 CCA red tops. A Yellow top battery of the same size as a red top is only 765 CCA and 55 Ah. I also believe the red top is the cheaper option. The test I saw was between the red top and the small yellow top.

So if space is an option, I'd go for the red top.
