Slow starting is a good sign of a weak battery.
For more modern cars: If you're in the 4-7 year range and the electronics
start acting up, failure is imminant. Typically, the ABS/TCS and Air Bag
lights will come on first, all other warning lights will follow, then the
speedometer may read wrong., the radio may turn off and on, etc. etc. If
this starts to happen, go directly to the shop, do not pass GO, do not
collect $200 and get a new battery.
I've learned to replace my battery every five years.
I had 'sudden' battery death in a two year old
Corvette C5. It wasn't from old age... the
positive terminal inside the battery case was
cracked and broke---looked like it had been
over-torqued at the factory.
Nevertheless, several of Steve's symptoms had
been present for a couple of weeks before this
left me...in the boondocks.
Most other Delco batteries I've have lasted well
beyond warranty (So Cal climate) but died
suddenly. If you value reliability, replacing
at the end of warranty is a good idea.
Back years ago (early 1970's) I was changing a battery on my car. I was
installing a new Die Hard. As I tightened the positive terminal the battery
exploded. The entire top came off hitting me in the face. The fluid covered
me and started to burn. The top hit me and prevented any fluid from entering
my eyes. My father lead me into the house and in the shower I went with my
cloths still on. I was very lucky I was not hurt but my shirt and jeans had
holes in them from the fluid. I took it back to Sears and they said the
positive post must of broke and shorted the battery. I still have fears when
I do anything with a battery.

Yeah, mine last about 25 years too. Ain't it great?
About as long as the warranty. Most are 60 to 72 months. You hear of
exceptions both diredtions, but the majority are pretty close to the rated
Slow cranking. New batteries don't seem to give the warnings as they did
I do it. In fact, my '01 LeSabre has a series 100 battery with an 84 month
"life" so just over a week ago I replaced it at 82 1/2 months. Cold weather
is here and I'm not taking chances of my wife getting stuck. I've done the
same on other cars too. If you can get to a shop for a free install, not a
big deal, but if you DIY, far better to do in on a 65 degree October day
than a 2 degree January day.
I have four fork lift trucks in the shop. Two were bought at the same time.
Batteries in both died within two weeks of each other, right at the expected
life of them.
There's a spirited discussion in another newsgroup
Summer heat here eats batteries (summer = april - november).
Five years is really pushing it. Mine last about 3-4 years.
When the headlights substantially dim when turning off the engine,
then it is time to replace the battery.
Don't know about pre-emptive strikes. There is a battery
place on almost every commercial corner so am not worried.
Probably 10-20 within 1 mile of my house.
In other words you never stray far from your house. Never far from home in a
snow storm or rain storm. Never in a high crime area in the city. I prefer
reliability over longevity. After all a battery only costs about $15 a year.
Nah, I don't worry about those things. I carry jumper cables.
There seems to be a Wal-Mart, O'Reillys, etc about every 5 miles in
nearby cities and towns. No reason to turn my car off in the middle of
