I'd expect a battleship to stay in operations for a very long time without spare part and replacements available. The battery will long be dead by the time they'll need it.

Wouldn't that depend on how often the batteries were actually needed? That is, if the system is primarily externally powered and only alternately powered by a battery (under various conditions), it shouldn't exhaust those charges too rapidly. Or like some systems I worked on, the batteries were strictly for things like maintaining a clock and some volatile memory, very slow discharge rates, when the aircraft were totally shutdown.

Why? What will kill it before then? What kind of a battery would have a long enough shelf life?

  Missiles tend to have molten salt batteries which have an excellent inert life: https://en.wikipedia.org/wiki/Molten_salt_battery https://en.wikipedia.org/wiki/Molten_salt_battery

An aircraft carrier needs resupply with avgas every three days when operating up-tempo. Warships use up resources like crazy, they're not going off on five year missions like Star Trek.

  ...avgas? I'd hope it get refilled with JP-5, unless the naval aviation field has suddenly moved back to piston aircraft when I wasn't looking.

    Indeed, although the article I found in Quora (from a carrier guy) actually used the term avgas and I didn't parse it :-)
