Has any one changed their car battery yet?
 

I'm thinking of changing my car battery before winter arrives. I've had my 2010 G37x for 4.5 years. It only has 30k on it. I usually only drive on the weekends for about 100-150 miles.
I had my mechanic check my battery and he said it's still good. But I don't wanna get caught guard and it dies out on me. I've read around online that car batteries should be changed before 5 years. I'm planning on changing it on my own since I saw a DYI on YouTube . What brands or type should I purchase? Any suggestions? Thanks.

I put in an Optima Yellow top about three weeks ago. Fit perfectly, no problems, looks nice. Works well with my audio system. Amazon has the cheapest price on it, at $169, but I got mine locally from Advance. This is the one that I put in:

Just take out the battery

On my previous 06 G35 when I priced batteries the dealer was only $20 higher so I had it replaced there. Everything worked when they were done.
I also had them install a 900CCA battery vs the 550CCA battery that comes with the car
If you keep your vehicle outside on the street and only use it once a week you may want to consider a higher rated battery as well.
I lived in Queens many years ago

I rebuilding a totaled '11 G37XS Sedan for my wife. Amongst the things stolen at Copart was the battery. The local Infiniti dealer had the best battery price I could find at $110. Even with the current coupon code Advance was $130.

Thanks for the advice guys.

I've had batteries last for 8 years, so why change it if it's still good. Don't throw your money away. If your car won't start one day, get a charge and then go out and buy a new battery.

i had to replace the one in my 2007 2yrs ago...

I've had mine replaced by the dealership while under warranty. I took the car in for another reason and they checked the battery and said it needed to be replaced.

2011 G37x. The battery was a little over 3.5 years old.

In my old car however I only changed the battery when it was on its last legs. 5+ years of use or longer.

i changed mine after ~5 years to a Optima red top. noticed slower cranks, and if i didn't drive it for a few days it would almost not start. the red top has lightning quick cranking. tons of juice. hopefully it holds up.

Did you need a height adapter for the Optima Red Top? Online stores had notes under the description that it was needed for the installation.

I uSed it when I installed mine.

Does the adapter come with it or do I Have to purchase it separately?

Just changed battery on wife's 2009 yesterday. Did it myself, only took like 10 minutes tops, easiest job there is other than changing air filter. Also advanced auto parts gives 20% discount if you order online and use code EXCM4, you still pick it up from the store, just get additional 20% off.

No & I live in the east coast and my car is a 2009. Getting my winter tires put on tomorrow and will have them check the battery since winter is coming.

I absolutely LOVE Advance Auto. I've been doing this trick for the past few years. I NEVER buy anything in the store anymore, unless it's like $5.

I recenly bought a $27 socket set for removing rounded bolts for $17 (with $10 coupon) and picked up in store the same day.

Advance Auto always has really good coupon codes...I happened to use the $10 off any $25 item coupon. There are some even nicer ones if you're spending right at $100.

Just do a search for Advance Auto coupon code, and most often Retail Me Not is the website with them.

I changed mine out at around June. I used AAA so they drive to wherever I am and installl an Interstate battery for me for around 140. And they have pro-rated replacements similar to that of Costco. If the battery dies within the first three years it's completely free and they come to your house to exchange it.

I have a '08 G35s 70k miles still running on original battery. The dealer checked it out and said it was good. And I am experiencing on slow crank yet.

I will never buy an optima battery again. The last 3 or 4 I put in my talon were absolute crap.

From here on out I'm only buying normal batteries and using the advance auto coupon "trt41". That's $40 off a $100+ battery.

Is this an ever-lasting coupon? Also, is it battery specific, or $40 any $100 purchase?

Just had the original battery replaced in my 2011. The car was still starting OK but the battery voltage dropped to about 11.9 V very quickly with the ignition off. Load test result was "needs charge"... This was the longest lasting battery I've ever had. Here in South Florida the heat usually kills them off in 2 years. Get it changed - it's not worth the aggravation of getting stuck somewhere.

Sorry for the late reply. It does come included with the battery.

Just changed mine yesterday. It died on me early Friday morning, and had been recharged every time tmit was at the dealership for the past couple of months. I guess the cold weather did it in.

I replaced the battery on my 2009 G37x last month since the original was getting weak. I don't want to begin the winter with a weak battery.

I live in South Florida too, and I have never had a battery last only 2 years. Mine last at least 4 years and a few even longer. I also have a 2011 G and the original battery is fine.

I wound up replacing my battery. My cranking power was low. Probably my own fault since due to my own stupidity this past summer I had to jump start my car one day. I had an Interstate Megatron Plus installed.

I had my 2009's battery replaced last winter. Car just wouldn't start, and after a jump and driving around for forever, it would not hold a charge. I also had my dealer do it with an upgraded cold starting amps because the cost difference was negligible.
