In general, an AGM battery of the same physical size will provide more juice than a traditionally constructed battery.

I personally like Optima batteries, but just as with Additives battery loyalists tend to get pretty vocal in their support of a certain brand.

I had an Optima orange top in my '97 Jetta that lasted 3 years until the car was totaled, and then we used it in our garden tractor for 7 years after that. The tractor wasn't started with any degree of regularity like a car, and always started right up in the coldest of conditions when it came time to move snow.

Hmmm...will be interested to have a watch on this. Never had a battery last less than 5 years in any car I have owned. My 2002 VW only had the battery changed once around 2008 before I traded it late in 2013. My wife's 2008 and 2010 Chryslers didn't need a battery change in the 3 years we leased each of them. She's currently in a 2012 Durango and about 40% through a 3 year lease. I HOPE that battery doesn't go, it's an AGM battery mounted under the passenger seat in the car and is a bit on the expensive side. Wouldn't want that extra cost on a lease.

OP: You are NOT the only one. My 2012 Passat TDI 6M battery lasted exactly 2 years. See the thread I started in November here http://forums.tdiclub.com/showthread.php?t=399702

^^^normal? No. Do some batteries fail earlier than others? Yup...it's the luck of the draw...

The OEM battery in our new in '02 Dodge Dakota lasted almost 9 years. When it went, I went to the dealer and asked for a direct replacement. No can do, I was told, and was offered something else. I went someWHERE else and bought an Interstate. Over the years I've never had one of those fail before we got rid of the car. If / when the battery in the Passat goes, I have no reason to believe I'd buy anything else.....

Default battery tender question

Sorry, not trying to hijack the thread. Are our Passats, positive grounded or negative grounded? I was going to start to use a battery tender, since I don't drive my Passat very far in my daily commute, only about 12 miles round trip. Haven't had any battery issues, but I thought I would try to get the most out of this battery. Thanks in advance!

Battery is on it's way out in less than 24 months(approx 48000 miles). Have had issues with the modules not going to sleep too when the car has been parked in the garage with key in close proximity.

Just thought I'd add mine along this thread for anyone else. TDI 2012, with 60,000 miles, battery cell went bad literaly overnight. Way to short a life, must be OEM batch.

The CR cars in general are harder on batteries. They have higher underhood temps, higher electrical loads, and have extended loads AFTER the engine is shut off in many cases. On the NMS they actually went to an even smaller battery. I have no idea why, but we'll see that shorter battery life may just be the norm for these cars.

Yeah, so yours is in the range of getting ready to go south soon. Don't think we'll see too many of these lasting 5+ years like we did with the older ones.

couple other items after you replace the battery, maybe it will help someone else later on:

You will get DTC trouble code and dash lights for: check engine, steering, ESC (deactivated), and TPMS

to correct and save a trip to dealer:

1. reset TPMS from glove box
2. check engine, use scan tool erase (code relates to "low voltage".. duh)
3. power assist steering will reset after you drive a short distance)
4. ESC will reset as above.

Even though labeled maintenance free, flooded batteries usually last a lot longer if you top them up with distilled water once every six months or at least once a year.
I'll have to see if the OEM battery in the Passat has removable caps.
The way the engine compartments are cramped these days the battery is usually somewhere in the cooling air stream instead of being behind a dead air space like they used to be. That doesn't work too well in a hot climate.
Doesn't seem to be brand specific either. I had a Merc and a Honda that had battery life of a little over a year, and a Saturn that was somewhere in between.
I try to replace with gel or AGM where possible, but you can't always find the size you need when you need it.
The Honda had some oddball size, but the flooded battery held up once I topped it up as needed.
Maintenance free my **s
