Leaving My Nissans parked 3+ weeks

Postby PalmerWMD » Sun Aug 29, 2021 2:55 pm

Due to an international trip coming up tommorrow I am leaving my vehicles (2008 Pathfinder 4x4 with the V8 and 2011 Xterra PRO4X) parked for 3+ weeks, this is how I prepared:

- Both were due for an oil change anyway, so got an oil change as I hate the idea of dirty oil sitting still in the oil passaged for weeks at a time
- I put one of the anti UV/heat shields into the windshields.
- Put a can of Seafoam into the fuel tanks as a mild stabilizer
- Topped the Pathfinder off with 93 Octane Non Ethanol fuel and the Xterra with 87 Octane non ethanol fuel
- Then drove each enough to make sure this fuel and the Seafoam wasnt just sitting in the tank but got into the fuel lines as well.

One thing I did not do was disconnect the batteries.

Why? I think of it as a test of both vehicle and battery, if it does not start I know I need to replace battery and/or I likely have a draw somewhere.

I am willing to take that chance as one of my vehicles (a 2011 Xterra) has the same size battery as the V8 Pathy (24F) but its oversized for that application (calls for 35) and its an AGM cell to boot.
So I am confident the XTerra will start and I have jumper cables to start the Pathy if need be.

So far the Pathy never given me any indication about being a weak starter so I expect it will start, but I do want to test it.

I understand all what your doing , good , but the battery part is definitely an 'experiment' , I know too , I know you know too :naughty: I gotcha . But 3 weeks is a quite long time , BMW's trash batteries like TEN days!
In any event , my opinion or guess FWIW is at least one , maybe two (perfectly fine?? ) batteries will become trash due to probable too deep or even dead cycle ie < 6 VDC ??

p.s. ANYTHING forming a conductive path for Pos / neg terminals like leaked electrolyte , dust , grease etc. Can & will add several milliamps to your quiescent (car off) draw , killing the batteries faster than if you wiped battery completely clean on ALL SIDES .

Older Bimmers typically draw a lot more standby current than a Nissan, about 3~4x in my experience. Even I-key Nissans draw only about 13 milliamps in hibernation, and keyed models are usually less. The cheapest group 35 is rated 44 amp hours, and lead-acids don't typically fall off the cliff into deep discharge until about 10% capacity. With a usable 39.6 Ah, that means the group 35 can theoretically sustain an I-key Nissan for 39.6 / 0.013 = 3046 hours, 3046 / 24 = 126.9 days before it harms itself. That doesn't mean it will start the vehicle in that state (it definitely won't), but it will still be above 10V and will take a jumpstart readily. More importantly, it won't be harmed significantly when recharged. That starts to occur in earnest at about 8.5V, and in that region anything more than a trickle charge will harm the plates.

For those who may not know, the funny "square white button" in the middle of a Nissan fusebox is an extended storage switch. Pulling it out disconnects backup memories in most of the car's devices and will cut standby consumption by more than half.

"Square white button" info very good info. Not included in owner handbook.

On most cars the only time it will ever be used is on the trip from the factory to the dealer lot. That's what it's intended for, to limit discharge of the brand new battery until the car can go through PDI and be ready for sale. That doesn't mean people laying their car up for months can't avail themselves of it. Just be aware that it kills practically all of the "volatile" memory in the car, radio presets, HVAC settings, vehicle preferences stored in the cluster, etc. Pretty much the only devices that won't lose their brains are the BCM and IPDM, so all that stuff will need to be restored when your trip is over.

I never know of the square white button's purpose. Good stuff. I seem to remember them being flat though, so pulling it might be a little tough. I'll have to look closer next time I'm in there.

Just got back to the US.
Both vehicles started no issue at all.
Hooray for good maintenance! :yesnod

I didn't check the voltage, but I could not discern at all, any difference to normal starting speed/sound of these cars.
(and i paid attention and am also very familiar with my vehicles.)

Both have 24F batteries , which is the stock size for the V8 (Pathfinder) and one step up for the V6.
The battery in the V6 (Xterra) is a Bosch Platinum 24F I bought in germany approx 1.5 years ago (but not a AGM like I posted at first incorrectly)

The battery in the Pathfinder came with the car but has tested out good.
I had it tested at 2 different shops with an eye to replacing with new ( as I tend to do with use cars) but both shops assured me the battery is good. This was in January/Feb.

No excessive draws but Nissan goodness. :yesnod
try this with a lot of other brands with a 10 year and 14 year old SUV and you likely will need a jump.

Well that's a very thorough reply , I Gotcha , I was kinda " Voltage curious " ,
Thanks Palmer ... I'll leave out the Weapons of Mass Destruction ???? ......Part ? LOL

Very well deduced. :yesnod
That was the original reason for those 3 letters due to my work.
The acronym has lost a bit of its common currency since then and CWMD has been in vogue and a return to the old standby of CBRN is also back in common usage.

MeToo late 90's Bechtel-Nevada , went to end of platform , 51 was mile 'o two over next ridge ,we were site seeing there - foreman said , with all our work we do in different "Areas", we don't stay more than 10-15 min , still very 'warm' . What's weird is they had a plaque AT THAT TIME that said the 'yield' was due to 75% Amfo + 25% Atomic (fission) Nuke , many years later that mix showed different in like wiki or youtube ?? I get the Amfo reduced the total radioactive atomic remnants & fallout for " cleaner " canal digs . Now that plaque seems to been " Fake News" ?

I see civilians can take NTS tours now like very limited times ?
