Car battery

A1404

My car battery seems to be at the end of its life, quick Google search reveals that i need AGM battery for Auto Stop-start system which i have it disabled (annoying thing).

Wondering if anyone know if i could just replace it with Non AGM battery with same capacity?

Anyone have ever ordered car battery from Amazon? Delivery to Ireland, they're quite expensive €200!!

No, you really should stick with a proper AGM battery

For a stop start system you should really keep to the same spec. Have a look on Mick's Garage, they may be cheaper than Amazon. My experience with Amazon is that batteries are a pain to have delivered anyway.

Those batteries charge faster than a normal battery so the alternator is probably different than a non stop start car. Id stick with the proper one.
In saying that it would probably work but may not last as long as it should.

Was in he same boat in the winter months, got a good price from local motor factors which was better than the online prices.

I bought a pair of manufacturer AGM batteries from Amazon fulfillment this past March. They supposedly were sent from the reputable original manufacturer where I've been buying AGM batteries for 20 years.

I believe they were counterfeit. Several things about them didn't look correct. They only lasted about 4 months where I usually get 14 to 15 months before they get weak. It didn't seem worth the hassle to try and ship them back to get a good pair after 4 months so I took the loss and replaced them through a​ non Amazon company.

I'll never buy batteries through Amazon again, there are too many bad reviews and complaints of counterfeit and poor quality reconditioned batteries being sold as new. I recommend you to pay a little more and get quality batteries from a local store, not Amazon.

You should go with same type as car is set to charge an AGM correctly.

I would not buy online unless you are 100% sure. There are many battery shapes, sizes, terminal arrangements, mounting types. Instead I recommend driving to local motor factors. Most will install the battery for you if you need them to, and you can be sure it will fit. It will also be faster if car is off the road.

Halfords have a good range of batteries. Check price on-line and with your local motor factors.

Yes to both of the above and local tyre outlets often sell batteries to.

Always good to buy local and might be a lot easier to get a warranty issue resolved if needed

Motor factors and spend the extra few quid to get a decent brand with a 3yr warranty. It's the most vital part of your car as nothing works without it... There is also some serious crap out there when it comes to batteries

Also depending on the car you may need diagnostics to tell the car it has a new battery, what model is it?

Yes car will need coding, my friend might be able to do that for with Vcds, looking at Tayna.co.uk seems to be cheaper AGM battery's.

Rang few locals, asking for +€200!

Car is Golf Mk7 2.0 tdi

Personally I would only go for established battery companies like Bosch or Varta. It not worth the hassle when it decides to go.

I agree go with a local supplier selling a reputable brand, it's just one of the costs of ownership

Wife's 2018 stop/start Polo has a system that seems to charge at a constant 13.3/13.5V when idling and driving with accelerator depressed, while coasting in any gear then the charging voltage is increased to 14.8V. All my previous VWs charged at a constant 14.3V which gave very long battery life.

True, its just bad timing for me and kinda low on money!, but all my locals were asking for +€200, i found online cheaper and top brand also.

I stick to getting mine from Halfords, whenever I had a battery fault on a battery from local motor factors they would quibble about the warranty because of it being a taxi, never had that problem with Halfords, it shows faulty they replace it as long as you have proof of purchase.

In fact had to replace one just last month, happy days my 3 year warranty is now a 5 year warranty as they replaced it with a better warrantied battery

I wouldn't be confident on that. Warranty doesn't reset if they replace the defective item. You can get lucky and the company might not notice but if they do you only have whatever is left from the original purchase.

Happened to friend of mine, AA replaced his BMW battery with a 4 year? warrantry battery, had to be renewed again 2 years later (failed cell) but he only got the remaining warranty period.

Ah I'll just have to see but AFAIK, they look at the battery for the length of warranty sticker, and look at the receipt for date of purchase, the receipt doesn't give any other details other than type of battery.

So first battery 3 year warranty would have expired 2021 new battery 5 years expires 2023.

Staff would have to be really on the ball I think to spot it, anyway time will tell.

Your 5 year warranty expires in 3 years! I hope you made a typo or else they have reset the warranty period from your original battery

I don't doubt that you will most likely get a warranty replacement in 5 years, but if you don't you have no come back

Yeah! that's what I said, instead of it having a 3 year warranty it has a 5 year warranty, 2 extra years if they don't spot it and I think highly unlikely they will, checked the shop codes and they are the same so unless there's a bright spark who says well all the batteries we had before that date only had 3 years, I think I'm safe.

Last battery I bought for a start/stop was BMW AGM and over €250 new. I ended up getting it secondhand off €bay for £50. You'll see certain sellers selling lots of them and they'll show a photo of the manufacture date. It was a gamble for £50 but turned out good in the end and still going strong 2 years later.

How long did the original stop/start battery last?, just interested to see what the "average" life span of a stop/start system/battery vs non stop/start, I know battery life can be like a piece of string but if one has driven the same make of car for years then a trend should quickly emerge.

Well mine was a 141 reg I assume it was the original battery when I brought it, first replacement was in 2019, warranty claim on that replacement this year
( battery was still fine as long as I didn't leave the car standing for longer than 2 days) but would take forever to get back to full charge, new battery even when it's low after not being used for a week will start the car and gets back to full charge in a 1/3 of the time the old one did.

My battery was stop/start and lasted approx 5-6 years and driven about 220k k/m on the clock.

In my experience against cars with no stop/start it's about the same on average.

patrickc

I just replaced mine it was 7 years old and had 220k on it

John.G

That's quite OK, be interesting to see how long the Polo's lasts in view of its eccentric charging pattern.

My yard truck is a 2003 Toyota Tacoma that I bought new in 2003.

The first battery, the OEM battery that it came with when I bought the truck new in 2003, lasted 12 years. The second battery I bought cheap lasted 2+1/2 years. I'm now on the third battery since 2003.

Why the original battery lasted 12 years I have no clue but, as long as it was working, I saw no reason to replace it.
