Battery replacement for euro standard — logbook Toyota Corolla Levin 1998

Because I have a Japanese car, the battery, respectively, too, i.e. small narrow 45Ah. He served me an honest 2 years. Let down only 2 times, last winter. But this winter, even at -5, I was deeply disappointed in it - the starter barely turned, I had to wake up at night and warm up the car with an auto start, and this is extra fuel consumption. In general, today I got tired of it and I went to buy a new battery, but already the euro standard, at 60Ah, with a starting current of 600A. also replaced the terminals. With the installation, in principle, there were no problems, but he went in with a stretch. I think I'll make it through this winter.
One of these days I’ll come up with something with its fastening - most likely I’ll redo it from the old one so that it doesn’t jump (in principle, it sits so tight)
PS: in the future, the plans were to install music - a subwoofer, amps, everything. and my last "small" akum would hardly have exported all this and whether it exported at all)
