The North American Northeast climate is very kind to batteries. Properly
cared for, a quality battery up here will last eight or nine years.
My original Panasonic lasted eleven summers and ten winters. Cranking got
noticeably slow towards the end, so I replaced it with an Interstate. I
just replaced that Interstate after eight years with a second one.
The 8-year-old Interstate could no longer hold a full charge, topping out
at 12.54V. Plus the seal between the positive post and the case had become
compromised, resulting in furry green corrosion, something I've not had
since my '82 Corolla. The post/case break happened in the last few weeks.
Plugs, definitely. Wires, no. I believe this model has a coil pack for each
I'm not sure about "very kind," but you can definitely get good
battery life up here. I average 7 years, as long as I don't do dumb
things like let them die from phantom loads in Winter. Basically, you
want to keep the battery as nearly charged as possible, with only slight
dips in charge to start, but without overcharging. You do that by
keeping the car in good enough tune to start quickly in all conditions.
This prolongs both battery and alternator life.
Yikes. Yes, plugs can fail as early as 60k miles. Wires last much
longer if they don't get baked by excessive heat.

Turn the dome light on. Now crank. Does the dome light dim a LOT?
Does the starter sound like it's actually cranking more slowly than it used
Do your headlights dim at idle, but brighten when you rev the engine?
If the above are true, your battery is probably losing its oomph.
