Happened to notice that the Battery Tie-Down (The piece that traverses the center of the battery) was getting coated with what one would typically associate with "battery terminal" corrosion (The flakey white type.) The battery terminals/cables themselves are clean.

Other than cleaning and coating with something like "No-Ox" (a product us techy types use in our station battery plants) was just curious of anyone else has experienced this type of (for me) rather unusual bit of oxidiation. It appears Nissan coated the terminals and lugs but not the tie down bar itself.

 

I have had this type coating form on both battery terminals and battery tiedown bars on previous Maximas, but so far, I haven't seen it on my '09 which was assembled 15 months ago.

 

Thanks Light,
I am assuming that the difference is the amount of time my charging system is running (3+ hours a day) generating a corresponding increase in gassification from battery charging that may take others years to develop (like on your previous Max's although from what I'm able to gleen you tend to trade up quite often!)

You are exactly correct that this powder accumulation is more a function of hours under charge (car running) than it is age of car. I have noticed this powder on all my cars from sixty years ago until this '09 Maxima (which will probably begin forming powder soon). It became particularly bad on the cars I drove over 200K miles.

I trade in the first year of each new Maxima generation, and, being retired, as well as splitting miles between the Maxima and the truck, I don't accumulate mileage on my car the way most folks do (less than 1K a month). Low miles plus keeping my car in perfect condition means my trade-in gets a 'certified' rating, and a larger trade-in value. For instance, I got over $14K trade in on my '04 SL about a year ago.

With your very high miles, you have no choice but to trade in reasonably often.
