Sudden dead battery - Is this common?

by Larry Coh » Mon, 01 Sep 2003 08:49:22

Hi,

Everything was going along fine; I parked my car for a few hours.
Never left anything electrical on, and when I got back and tried to
start the car the battery was completely (And I mean completely - no
dome lights, dashboard lights, etc.) dead [The battery is 7 years
old]. I got a jump and with the alternator supplying electricity
everything was fine. After driving for an hour when I got home the
battery was just as dead. I put a voltmeter across the terminals and
it only registered 7.5 volts (I would have tested it with a
hydrometer, but the battery is completely sealed). I have since put in
a new battery and everything works fine.

I thought batteries died gradually. How does a battery die suddenly,
and does this happen often? With any other battery I owned it
gradually deteriorated.

It WAS deteriorating; you just didn't notice it. You lost a couple of cells.

Actually, you got about 2 more years than I ever get with a battery. Keep
the terminals clean, and don't sweat it for another 4 years or so. <g>

I have had two die on me in the summer. Car running fine, then go back to
start it and
either nothing, or a small click. I think what happens is a internal lead
bridge between
the cells opens up or gets a high resistance contact. They don't make them
like they used
to.

Yep.  They die quick and right now with cars running scads of electrical
items: computers, electric pumps, injectors, always-on driving lamps, etc.
Mine, in sunny (read hot!) CA, only lasts about 2-3 years and it doesn't
matter how many months they guarantee it for, they just the pro-rate
warranty exchanges for another.  Last one died between first and second gear
crossing an intersection.  Just shut down completely and had to push car out
of intersection.  There is little, or no warning now when they go.

Oh yes, always charge up a new one too, else you will never achieve full
charge.  Supposedly the Hawker Odyssey batteries are the best going now for
high heat environments - but very pricey.

Seven years is about all the warning a guy can expect. What makes a
person that owns a volt meter and a hydrometer go seven years on a
battery? I would bet that a check of that battery a month ago or a
year ago would have shown low voltage and low capacity. We'll never
know.

Yes.  Since it happened to me a couple times 20+ years ago, I just replace
the battery on a schedule every 4-5 years as a maintenance item.  Best to
replace it on my terms than on it's term.  Since I started doing that, it
was the last time I was ever srtanded by a dead battery.
