My 2010 Sedan still has the OEM battery in it, Seems to be working fine I have topped of the cells with distilled water last year but other than that it seems fine. But with winter coming up and it's stored in a very Hot garage 5 days a week only driven onthe weekends. Do you all think I should replace it before it craps out this winter. And if so which battery would you use Die Hard, Red Top etc... ? Thanks' ahead of time.

 

Good point. My brother had an 09 coupe that left him stranded 3 times due to the battery.

 

get a vmeter and check regularly..
08 coupe here still with oe battery... northeast winters

 

I too have a 2010, and last summer my battery died while playing the radio with the ignition turned off in a parking lot waiting for a meeting to start. I have almost never been so embarrassed in my life. I had owned the car for about three months at that point. I had it jump started, drove it to a Dealer who tested the charging system and pro-rated me a battery for $95. I couldn't quite understand the pro-rated part, but at least I didn't have to pay full price.

 

2011 OE battery, garaged kept . . . .

 

I'd replace it. I just had the battery replaced in my 2010 because it's five years old now. But it's up to you.

 

My OE battery died at about 3 years.

 

Take it to your trusted neighborhood mechanic and have them do a load test on the system. That's the only reliable way to determine the capacity of the battery. A voltmeter only gives half of the information. The load test shows how much current (amperage) the battery will supply under demand.

I just replaced the OE battery in my 2010 a few months ago. A visual inspection while checking the water level in the cells showed that several of the plates in the cells had warped. There were no performance problems apparent. I had it checked by my local mechanic and it was below 50% capacity on a load test, so it was replaced. Remember, it's usually not the cold that kills the battery, it's the summer heat. FWIW, I put in an Optima Red Top.

 

Replaced my OEM battery on my 2010. Bought the car in March of that year so I am sure it was built in 2009. Had to get jumped a few times after just 10 minutes of running in Accessory mode. Replaced with an Exide 24FX from Home Depot. $100.

 

2010 G Mine just crapped out on me a few months ago.

 

2010 sedan here. Still with original battery, yes its died on me 2-3 times but it was nothing out of the ordinary (me leaving the lights on for a few hours), once over night. Never had problems starting up. One time though when it died (a week ago), it was near impossible to get it jumped, 3 diff friend's cars and a bunch of diff cables and it just would half-start, iwas sure it was gone for good, but then it kicked back up, and still been good since. Does extreme difficulty in jump starting a dead battery indicate poor health?

 

Yes and do it today before you get stranded as others have mentioned

 

What he said. Ounce of prevention and what not.

 

I have a 2011 G37 Sedan - although I only bought it a year ago and it came CPO with a warranty to 100k - think I should just replace it or assume it's been replaced since they did the Certified Pre-owned stuff..

I also carry this in my trunk so I am not worried about getting stranded.

 

This will help if you're unsure how old your battery is.



I'm not a proponent of replacing items which are still functioning. However, a battery will only last for so long. I would say the average expectancy on OEM spec batteries for our vehicles is 3-4 years. That isn't a hard rule. YMMV. When a battery begins getting long in the tooth, it is one of the exceptions I make to purchasing a replacement part for prevention purposes.

Informative Note: A battery charger doesn't help much when you have a dead cell(s).
