‘06 Odyssey since new
86,000 miles
Battery 2-3 years old

For a few years, battery would simply discharge. Trav mentioned some time ago about a parasitic drain and I only looked into it further this holiday season... at the time, fully charged battery with no drain taking place (25 ma was all the registered)

Been using a portable pack jump starter which has been working well... when car started, made sure to use it/keep it running a long time to get a nice charge. Next day, car would start even during that freeze a week or so ago. If a couple days went by without trying to start, I’d need a jump

Throughout yesterday into today, the car would turn over with the jump pack and start but immediately die out. I mean 100% die out with no dashboard lights or anything. Jump again and would turn over slowly but not start. If I wait a while (60 minutes +), I can do it all over again... fast turn over, start, die

This is a new development as of yesterday

What the heck is going on? What did I break?

Next Christmas, I’m asking Santa for a horse

Why didn't you just disconnect the battery when the car sat, if you knew it had a drain?

Repeated discharges of a car battery is not good for it's longevity.

Sounds like a bad battery connection. Take the battery cables off and clean them with a wire brush.

You need to do a parasitic drain test.

Check the battery connections, test the battery and charging system first.

I'm thinking this is a good test to do in general. So you don't find out you have a parasitic drain when it's too late

There is no mention of voltage. To me that is issue #1. Sounds like a low to medium impedance short in the battery.

While some pple check the battery (+12V red) cable, few check the engine ground (black) cable back to the battery!

Sorry guys... I should have been more thorough in original post

Tested for drain 2 weeks ago with a fully charged battery... 12.xxx volts when test was done

Made sure everything was off... only thing possibly pulling juice would be the clock

Connected multi meter and draw was only 25 ma. Despite low draw, I pulled about 20 fuses just to be sure... nothing made a dent in the 25 ma

Now, there’s every chance that something could have opened after testing so once the car is up and running, I’ll go thru it again

In the meantime, if the battery connections pan out, what’s the next step? What would cause an immediate shut-down and total loss of electric?

Thank you

12.xx isn't good enough. Parasitic drain from the vehicle is irrelevant if the energy is dissipating inside the battery due to an internal short.

A battery with such a short will discharge to 10.5v or lower as the cell is lost.

JHZR2... would that cause an immediate shut down of the vehicle once started.

Just happened again:

* Removed and cleaned the terminals and posts on the battery
* Tested negative connection/ohms across several areas in the engine compartment
* Made certain the absolutely nothing was on inside the car. Even turned off electric side door switch as well as auto light switch when opening any door

- set up jumper pack and car turned over full bore but didn’t start. Give it a few minutes rest, turned it over and it fired right up.

Before I could even depress the gas pedal, immediate shut down. I mean everything on the dash went completely black and turning the key didn’t absolutely nothing

I hear what you’re saying about the potential for an internal battery problem, but once started, the alternator kicks in, right? Pretty much instantaneously...?

Not arguing the point as all because I’m a babe in the woods here, but if the car starts and then dies immediately, doesn’t that point to a problem outside of the battery? The battery did it’s job

How would I check for an impedance short within the battery?

This is starting to get on my nerves

Thank you

IMHO 25mA is too much and will cause the battery to drain. I assume this has happened quite a bit and the battery is probably had it. You all circuits off should be around 5-10 mA.

Had this very same thing happen to me a few years ago on a ford Taurus. It turned out to be one of the circuit boards on the radio face.

Its very hard to tell anymore what the base current draw is as there are so meany timed circuits that are actuated after the car is shut off and doors closed.

Always best to start with pulling the main engine fuse box fuses first.

You need to have the battery and alternator tested. The draw is not the cause.

Besides the obvious battery causes, a bad alternator rectifier diode can cause this. If you can drive it to a store, it can betested for free. A quick home test if you get it running is a multimeter in ac mode (google ripple voltage, alternator, etc).
