Think I should buy one this weekend. I used to DD my Z but I moved a year ago and only use it on the weekends. Starting it up tonight it barely wanted to turn over, so it seems to not want to hold a charge.

Stock battery.
41k.
2 years and 1 month so far.

I'll probably get the red top Optima.

3years 5months 18,800 miles still cranking.(I got it used 16months ago with 10k miles on it I imagine its the original battery) It's my DD but I don't go far. Take the highway to and from work just to open it once a week.

Well there is a draw on the battery. Blinking dash light. However small, still a draw. And over a few months, it will drain the battery. I used to park my Z for up to 5 months. Yes, winters here suck! Many times, there wasn't enough to even turn on the dome light. After charging, everything worked fine. I only had my Z for 3 years though.

But I do sell batteries and I've always believed that after 5 years, you've gotten your money's worth and are kind of rolling the dice. The oem battery is nothing to write home about, but you should probably get 4 or 5 years out of it as a D.D.. Storing the Z and not giving the battery some kind of maintenance will shorten the life span. And by maintenance, I mean trickle charging with an automatic (shutting off) type of charger. Adding water shouldn't be necessary unless you over charge it. (Thus the automatic charger.)

Mine is 4yrs old and ready to be changed. Daily drive, 32k miles, 2 winters driven and 2 stored. She's on a trickler this year and the charge isn't holding well.

you check your water level at all? im going to be checking mine this summer.

trickle chargers can be bad for the battery as it cant stop charging like a battery manager (tender) which floats after full charge.

was just wondering the same thing about battery life. Have 09 370z Touring w/ 28000 miles on her. Already replaced battery once and this morning on way out the door to golf.....slow cranked twice and then died :P Voltmeter was reading 14.4 yesterday...I'm guessing the OEM battery only lasts about 2 years

kenchan

if going by the car's volt meter, you have to look at it while your car is ON but engine NOT running. otherwise you're only seeing the volts the alternator's cranking out (14.4v).

for the true test, you need to use an ammeter test to get your cca.

Still on the original battery on my 07 HR and I have 2 - 12's so it gets a workout! I've never seen a battery last this long.

My Z is on original battery - 11,700 miles and 2009. Of course it appears to have been parked most of it's life since 11,233 when I bought it divided by 4 years is about 2800 miles a year / 233 miles a month approximately. I opened one of the reservoirs the liquid level was about nominal on the first one anyway. I hesitate to add any distilled water in the fear that I'll accidentally put too much and then have acid splashy issues from sloshing up out the vents.
I wouldn't be shocked at all this summer if it went belly up but for now appears to be fine engine off levels look OK.

my car is around 12K miles an 09 as well.

when i added distilled water to my G's battery (i do this every 2yrs) i use a small squeeze bottle like this. i just peek inside while adding so that i can monitor the plastic indicator inside. the indicator just needs to make contact with the water.



make sure to wear gloves and goggles. just in case.

I wish Nissan used the same OEM batteries that are used in Miatas. My girlfriend's is eight years old and still going strong. She thought about replacing it because of it's age, but doing some investigation it seems 10 years is pretty normal. I'm sure some has to do where you live, but she is here in Chicago which will certainly test a battery. Panasonic makes them.

4 years 50,000 miles finally going out

Mine (09) is still on the original battery and I have noticed recently that it is taking a bit longer to crank.

No winter driving and stock stereo?

What do people recommend for a replacement? Optima?

My original battery ('09, just turned 20k miles) is still going strong. I had to add some water recently (dealer couldn't seem to handle the job even after discussing the fact that, no, my car did not have a maintenance-free battery).

Battery technology has made some major leaps in the last decade or so and even a cheap battery is pretty good nowadays. Use the site search feature for more info and opinions.
