Default Battery replacement - Is venting necessary?

2013 Golf TDI

Battery completely dead on a Sunday. Need it for work, cant wait until Monday to get an oem dealer battery.

Went to wally world and bought a EverStart Maxx Lead Acid Automotive Battery, Group Size H6. Borrowed neighbors socket and after much fumbling around I got it plopped in.

New battery had a plastic pouch taped to the side of it with a couple plastic pieces for venting.

Unless I missed it I didnt see anything attached to original OEM battery when removing.

My automotive skills are nonexistent. Am I supposed to do something to vent the new battery?

On a side note, the battery gave no indication of failing. Driving around yesterday no issues. Today dead as a doorknob. Car 3yrs and 5 months old, 34k miles. Do they normally go dead with no prior indications?

Thanks for the help!

Some batteries are mounted inside the car.. like under the back seat of my buick.. these batteries MUST be vented through the little tube, to the outside of the car.

I believe the Toureg also has a battery under the drivers seat, however its a Sealed battery and has NO vent,,, if I understand it correctly from what I have been told.

If yours is under the hood, no problem.

It has been my experience, and the experience of others on this forum, that modern batteries do act this way. Works fine one day, then will not start the car the next.

I think part of the issue is that modern cars have a constant electrical draw, even when the car is locked and the modules are "sleeping". The module or modules need to be have awake to listen for that key click to unlock or to monitor the car for break-ins. And if there is an electrical problem (broken wire, module with a short), there is more of an electrical drain without any indication.

3 1/2 yrs is premature failure which can happen ,but isn't the norm. My 09 JSW TDI battery is original and fine. I will probably change it this yr just to be safe.

Did you get the 615CCA (2 Yr warranty) or 725CCA (5 Yr warranty). CCA=
Cold Crank Amps. I have had two WalMart batteries, great value and
work great. The first was the H6 Size 615CCA, got it because that is all
they had stock, however the 725CCA with longer warranty is far better.
Difference in price $107 vs $117 makes the 725CCA version a winner.
SAVE YOUR RECEIPT... and photo copy it. The thermal printer paper
receipts self erase after a few years, especially if you leave in car.

I am happy with Everstart batteries, except in my research some people
complained store gave them a hard time about warranty return. Non issue,
if you remember your receipt and this tip. Call the "Everstart Battery Hotline"
at 1-888-387-8278, while at the store. They will be instructed to get the
be instructed how to get it done.

You are good, these "sealed" batteries (vented but has a cap/cover that
recycles the gas off when it charges. Gas by the way is hydrogen.. aka
Hindenburg.

That is normal and par for the course. The failure mode is often sudden
death, normal. My OEM battery did that. My first H6 from Walmart got weaker;
it did not fail suddenly. I have a battery tester and the CCA capacity was going
down, and it seemed to lose too much volts after a few days of inactivity. Replaced
the 615 WalMart with the 725 WalMart Battery, excellent. I noticed the difference.
I left my parking lights on for 6 hours recently by accident in very cold weather. No
problem. Nothing like a strong battery, gives you reserve power.

Thanks for the help everyone! Started right up this morning and codes were cleared by the time I got to work.

I bought the 730CCA version with 5 yr warranty it was the only model in the size I needed they had in stock. As long as it lasts me until 2018 I'll be more than satisfied.

Thanks for the tip regarding receipt and warranty return, much appreciated.

That battery will last 5 years.... the OEM Bosh battery is designed to self destruct at 3 years.

I found 3 1/2 years was about normal for the batteries in my 2010 Jetta. Most recent replacement was just out of the window for no-cost replacement, but still was less than half price after pro-rated. And, very little warning...maybe one or two sluggish starts.

My battery only last about 2 years in harsh Central FL weather. I'm on the 3rd battery as the car is about to turn 7 this August. Last battery died on me in Aug. Just right on time.

I hate shopping at Walmart, but they are there when needed. I bought my battery there several years ago when it died suddenly while shuttling the daughter around about 10 pm the evening before leaving on a trip early the next morning. It died at the daughters friends apartment 2 blocks from a Walmart. Guess I was thankful it happened then and not the next night while out of town. Bought the best one they had on the chart for the TDI and its been good for 3 years so far. I remember it being about $120

Before the failure, the wife complained once of a slow start, but she has left dome lights on in the past so didn't think much of it when it seemed fine the next morn. that was just a day or two before the failure. So my OEM lasted 4.5 years. Sep '09 to May '14

Battery manufacturing plants are not on every street corner, and stickers can be stuck to any battery case so brand names are not so relevant as you think.
Last time I looked there were very few manufactures selling to everyone.

Exide, a very old name in cheaper batteries. Tire store and used car lot favorites. Will get down the road just long enough...

Johnson controls, over half the batteries are made by them under some famous names as Interstate, Delco, Costco, Some Sears, etc. Pretty good overall, my only complaint about them is acid leakage around the posts and acid gassing under the hood eating battery cables and holddowns and cars in general, but not near as fast at that as Exide.

I use a brand marketed by a parts store chain with their name on it but is deep down a company called East Penn. They seemed to really grow about the time Delco quit manufacturing batteries so I surmise they must have bought their old factories. Good quality with NO leakage or excessive gassing which are my top concerns long range.

Ask someone who knows, who made the battery to be sure, but if it isn't East Penn or JC I really don't want anything to do with it.

I believe the Toureg also has a battery under the drivers seat, however its a Sealed battery and has NO vent,
The Toureg drivers seat battery, at least the OEM does use a vent as does the rear battery. DIY battery replacement and save about 500 bucks or more.

Another thing to keep in mind is that later model VW and BMW have to have the battery registered after replacement to reset battery management.

On those cars we have learned that the factory battery is the best choice regardless of price. Use the exact same part number to be sure. Sure the internet says you don't have to, and i always trust internet info.

We had a gentleman who needed a battery for his 7 series. He called up the dealer and got an exact replacement battery but didn't know to register it. We saw the car a year later and it had overvoltage codes. We replaced the defective alternator and registered it. Yes we had to register the alternator too. We also had to replace his one year old battery that was cooked.

We tried to get it warrantied from BMW for him since it was indeed a factory battery. BMW told us it was no problem to warranty as long as he had documentation showing that the battery had been registered at replacement.

Very expensive mistake, and he was not trying to cheap it out in the first place, he had bought the original factory battery.

On late model cars we will not use anything but dealer original batteries.

Ugh - No start Saturday night. 7yrs, not too shabby out of the OEM battery I guess. A quick trip to Wallyworld and the "Replacement Computer" sent me home with a 47N which is about 70% of the physical size of the OEM battery...

Once installed it was seated well enough but hardly satisfactory - seemed like the fender side lip didn't quite fit. I guess I'll go back tonight with the OEM one and compare what they have on the shelf in hopes of getting something closer.

Stopped at Cambodian Tire on the way home and grabbed the the right size with 850 CCA for $17 less... Took it back to Walmart, no questions asked.
