Panel battery swap vs. full board replace, took the cheap route on a 70 year old house

Went to swap a dead backup battery on a DSC panel in a 1940s row home last Tuesday and the terminals were so corroded the board traces were peeling. I had maybe $30 worth of parts for the battery and a $140 board on the van, but the owner just wanted it working before their inspection Friday. I cleaned the terminals with baking soda paste, replaced the battery, and it held up through the weekend, but now I'm wondering if that fix is just a ticking clock. Any of you ever walk away from a patch job like that and actually feel good about it later?

That battery will probably outlast the panel anyway, those old boards are tougher than people think.
