Battery dying

[Fred Nurk]

One of the problems with the batteries is that since they're generally designed to run in cold climates, they fit additional insulation around the battery to keep it warm (battery capacity goes through the floor under cold enough conditions). However, where I am, it never gets that cold, and the hot temperature gives the battery extra cranking capacity at the expense of its service life.

The mechanic who replaced my Tiguan battery (first one failed just under 3 years old, was replaced under warranty) pulled the thermal insulation from the battery. A mate of mine with a Wolfsburg Golf had RACQ come out and do the same thing when they replaced the battery.

That said, replacement AGM on my Tiguan was quoted at around $350, so its possible to not have to pay $600. If its under warranty I'd be pushing it back to the dealer, regardless of 3 year or 5 year warranty.

There’s no harm from the battery insulation, it may actually shield the battery from the under the bonnet heat generated by engine. Our 2010 Tiguan std battery was almost 9 years old and still starting ok, when I’ve replaced it, had a double layer insulation on it.

what year and model Tiguan is and can you post here from Battery sticker brand and model number ?

Anyone had to have their battery replaced?

It was flagged at our second annual service as needing replaced, but the cost seemed high so I declined.

Our cars keyless entry is only working intermittently now....

What is a reasonable life for a car battery these days?

Usually 3-4years anything above 4years is a bonus. That 3-4 years is from the day the battery was manufactured (or your car).

My previous three cars (non-VW and bought 2nd hand) all required a battery replacement around 7 years.
None had stop/start

I would expect anything less than 3-4 years not acceptable

My non VW SUV lasted 6 years with no S/S functionality.

9 years would have to be a record. I have never had a car battery last that long, especially in an SUV.

Our Polo only used for short shopping trips and 4 trips of 100k a year was new Jan 2011 and still has original battery and starts first kick

In contrast in winter in NZ in an XF falcon taxi I had 2 that lasted 3 months only and they were huge tractor batteries. Heated rear windows killed them

Its a 162 R-Line, picked it up new in March 2017. Intend to give the dealer a ring on Monday to see what they are willing to offer.

Hillbilly, Mazda petrol engines use spark to help initiate cranking, the diesels don’t. My car was a diesel. Also there is still a short time where a bit more fuel is used to increase revs and overcome inertia/friction forces, before an engine is idling efficiently.

It’s also No-ones place to tell another, whether they should or shouldn’t care about something. Please refrain from ever communicating to me your thoughts on my purchasing decisions. It’s just not the place for it.

Please do feel free to correct me- if you see something I’ve said is absolutely wrong. I enjoy learning and improving my understanding of topics. As a previous Mazda employee and vehicle user I am very aware of the systems used (for 2008 to 2018 models)- both advertised and actual. I’m sure you’re aware of the important difference between the two- in many aspects of life.

Cheers.

Is Mazda using STD battery if their system in order to restart doesn’t need to crank the engine using starter motor and battery? Or do they use AGM or EFB battery and why’s that?

I’m just curious, that’s all.
