Re: 98 GRAND CHEROKEE BATTERY BEING DRAINED Part 2
Just to claify a few things.
All batteries have a power curve and it varies from
model to model. Here is one for a standard AA battery. (e91)
http://data.energizer.com/PDFs/e91.pdf
Flip to the second page and look at constant power discharge.
(I went through a lot of this figuring out what batteries
would last longer in my GPS unit) The Energizer and e2
profiles are almost identical so the only thing you got
when paying out the noze for an e2 was a warm fuzzy.
Anyhoo, back on line...
Feel like watching a slide show?
http://nms.csail.mit.edu/fun/battery.ppt
Optima self-discharge curve.
http://www.dcbattery.com/optima_self...rge_curve.html
Hope that helps clear things up.
The only sure way to test a car battery is a load
test. Most PepBoys and probably C-Tire (Tyre?) :)
will have a setup. This is a computer that charges
the battery then does a controlled and timed discharge.
FWIW, I've brought dead cell batteries back to life by
using a charger (high amp) and a volt meter to bring the
battery up to the service maximum 5-10 times in a row
and then using a low amp trickle till all cells bubbled
the same. I don't suggest doing this without eye
protection because you will bubble the cells quite a
bit and that's acid that is popping out even if you can't
see the microsopic drops.

Re: 98 GRAND CHEROKEE BATTERY BEING DRAINED Part 2
Well ----
The garage called and turns out the battery was defective as I indicated and
I was given a new one.
I don't want to flame anyone or blow my own horn, but I have had education
in power distribution for aircraft and lead acid battery maintenance was
part of it so I know what I talking about. When it comes to present day
automotive I am just as ignorant as most with the many different modules and
computers that control systems, that is why I am here to draw on the
experience of others. Now I just have to figure out what is activating the
solenoid, do not have wiring diagrams to follow. Give me a good schematic
not block diagram and a simple meter and I would not have much of a problem
except for the modules and computers.
Seems like this thread is getting out of hand so I will start a new one when
I have the time to continue trouble shooting the fault.
If measuring dead batteries makes you an expert well good for you.

Re: 98 GRAND CHEROKEE BATTERY BEING DRAINED Part 2
Well Matt
Sorry that I have only been an operations director at several
aerospace firms, including General Dynamics and Litton, which included
responsibility for test and calibration labs. Apparently, my
aerospace experience doesn't match your education. Oh, did I mention
that early in my quality engineering career I performed product audits
on spacecraft that landed on the moon? With that background, how
could I possibly know anything about something as simple as a
lead-acid battery?
If you want to learn something, instead of just arguing, pay attention
to the post by DougW above. Pay particular attention to the discharge
curves which show clearly that battery voltage DROPS as it discharges.

that early in my quality engineering career I performed product audits

lead-acid battery?
If you want to learn something, instead of just arguing, pay attention
to the post by DougW above. Pay particular attention to the discharge
curves which show clearly that battery voltage DROPS as it discharges.

Well Matt
Sorry that I have only been an operations director at several
aerospace firms, including General Dynamics and Litton, which included
responsibility for test and calibration labs. Apparently, my
aerospace experience doesn't match your education. Oh, did I mention
