End of story : I bought another battery directly from a Nissan dealer instead of the one I bought from à generic store, my MO restarted at first attempt

"I bought another battery directly to a Nissan dealer"
Yes, there is a special security chip in Nissan batteries. <VBG>

All kidding aside (and hoping no one at Nissan decides to take up my idea!) here in the US, a dealer-branded battery comes from one of the major battery makers, and the local distributor slaps on the dealer lable (for many brands) before delivering it. So there is nothing special about "genuine" batteries.

There is also a general problem in the battery business with batteries sometimes sitting too long on the shelf, either in transit or in the stores. Something like five years ago, JCI had their premium Optima AGM batteries on sale because they had some sitting in channel for over a year. With conventional batteries, even two months in channel will cause problems. Or, you might have simply gotten a defective one.

Without the special Nissan security chip in it. <G>

Weak or dead batteries cause a lot of problems that folks sometimes spend a lot of time and resources trying to track down. It's generally wise to check the battery when problems start cropping up.

I agree that guenuine batteries can stay for a while on a shelf, the good thing with the Nissan dealer is that they test the battery before giving it to you with a charge report, simple but shows the quality of the service...and the Nissan battery was cheaper of 10€!!!

they may test the battery, but based on reports here, I have concluded that the life expectancy of a Nissan battery is about 3 years; four if you're lucky. We have read more reports of battery problems on this forum than any other forum I have ever participated in.

I don't ever plan to buy a Nissan battery as a replacement - waste of money IMO. I can buy better batteries with more cranking power for the same or less money.

I don't know the average price in the US, in France I paid 140€ for the new one (Nissan). The Nissan guy confirmed me that I can't expect more than 4 years with the new one, to be compared with the 7 years of the old one ! (everything was in japanese on the previous battery).

From what I understand, the replacement batteries offered by Nissan are made by a different source as compared to the OEM batteries. That makes sense to me, because the OEM battery is most likely sourced from Japan, and the replacement batteries made in the USA.

when the day comes to make that change, I'll be taking it to my local shop and letting them struggle!

Struggle? As with most cars, changing the battery on a Murano is simple - no struggle at all. That's why many car parts places these days do it for free. Paying a shop to do it is (IMHO, of course) wasted $$.

 

[Pilgrim]

If someone thinks changing a battery is a struggle, I assume they have a shop do everything possible to a car. There are few things easier to do yourself. OTOH, it's not a labor-intensive process so you don't save a ton of money doing it yourself.

And if the poster asking the question had read some of the battery-related threads on this forum, he would be aware of (1) how terrible the Nissan OEM batteries seem to be, and (2) how incredibly sensitive to poor battery performance that the Murano seems to be.

Changing a battery should be a 10 minute operation

It WAS on my 04. Hard to believe it's that much different on an 09.

It's not. It just depends on the planning and mechanical skills of the person doing the operation. When i replaced my battery, I doubt if it was disconnected for 90 seconds. But I laid everything out, and it was easy to be quick.

If you think Murano batteries are a big deal....we have it easy:

On my wife's '09 BMW, when changing a battery you need to take the car to a BMW dealer (or a shop with a $300 tool) and have the battery "registered" with the car. The BMW system monitors every cell in the battery and must be introduced to the battery properly to carry out its intended monitoring function.

I'm dreading (actually, more like anticipating) eventually needing this on my 08 335xi, Pilgrim. Especially since the build date was 7/08 and the original battery is now 5 years old. They say if you can afford these cars, you should be able to afford maintaining them - but I'm so used to Nissans, some typical bimmer quirks like the battery registration still seem strange to me.

Just changed the battery in my 2010 MO, very easy to do. I hooked up a battery charger to the positive cable and the chassis to keep the memory settings. I had to remove the fresh air intake housing (2 screws) to gain full access to the battery. Used a Duracell series 35 from Sams club.

You definitely don't have to use anything to retain settings OR remove anything else to change a Gen. 1 battery.

Not that big a deal to me. If I have to pay for the battery registration once every 5+ years, I can manage. I'd prefer not to, but wottheheck. For that matter, I'd like to have a dipstick on her 328iX too, and the Ubergruppenfuhers at BMW have decided that the car doesn't need one.
