My present Yuasa cargo 640SHD 115A/H 1000A on the old S2 is coming to the end of it's useful life after only about 4 years.

Any recommendations for a good quality, long life replacement battery, preferably with a reasonable guarantee.?

Thanks Steve
 
+ 1 on Tayna, They've always got a good range of makes / guarantees to fit different budgets.
I've always gone for options with 5 year warranties & always had the battery outlive that by many years.
Always get the biggest that will fit the battery tray by checking the actual dimensions, never what's recommended by the likes of Halfords etc

Varta batteries are lasting well, have just replaced two that were 10 years old, and one of those is still good !

Maybe those which were made 10 years ago were good, for the last 6 years i really doubt they do the same job, i binned a Varta and a Bosch which both lasted only 2 winters and got weak on the 3'rd then bought a Bullet from Tanya https://www.tayna.co.uk/car-batteries/bulletbatt/c31-1000/ which is far better
 
Thanks guys, there's a wealth of knowledge out there and I appreciate your assistance.

Let me clarify a little more the questions which was more about technology and original manufacture as opposed to good dealers. Today there are a number of alternative technologies available as opposed to the good old lead acid cell known as the "flooded" battery, such as AGM (Absorbent Glass Mat) and even LiOn. The AGM battery used a lot in Stop/Start applications, offers a low discharge in passive states ( sat in the drive all week) and can offer a longer (two to three times) service life as opposed to the normal flooded type. It should be a direct replacement for a flooded battery and needs no specially charging technology, just what's on the car.

Regarding our friends Halfords, they offer at £116 (includes trade discount) a slot in exact size replacement 80 A/H 800 amp cold crank AGM replacement for the S2 with a 5 year warentee (replace with new over the local counter). Halford batteries if I understand it correctly are badged Yuasa batteries.

The prices for the C31-1000 series of batteries on Tanya look competitive, but all the S2 series offerings are wet technology and 3-4 year max guarantee.

So any thoughts regarding AGM as opposed to flooded and the Halfords offering?
 
80 A/H 800 amp cold crank AGM
First of all never fit lower AH battery than it was factory fitted which means 110AH/850CCA also for the AGM to last it needs a temperature sensitive smart charging system while the D2 has a rudimentary one which can also suffer due to the AGM's lower resistance. Any C31 -1000 from tanya would be the best choice for a Td5 just accept the fact that nobody makes batteries to last more than 4 - 6 years these days, especially if you make short trips and dont charge it to full at least twice a year.

With your obvious knowledge about all this, why not fit the 80AH one you mentioned and then let us all know how you get on?
It might make an interesting thread all on its own.
 
I can tell you on the D4 you have to tall the car what type of battery is fitted so it can change its charging algorithm, so you may find the agm might not do well with a std alternator frying its arse off?

My knowledge of batteries over the years is as follows, bigger is better!

+ 1^^^, here's the gist of it: As with all gelled and sealed units, AGM batteries are sensitive to overcharging. A charge to 2.40V/cell (and higher) is fine; however, the float charge should be reduced to between 2.25 and 2.30V/cell (summer temperatures may require lower voltages). Automotive charging systems for flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell); a direct replacement with a sealed unit could overcharge the battery on a long drive. source https://batteryuniversity.com/learn/article/absorbent_glass_mat_agm ,

the D2's alternator is not suitable for AGM battery that's a fact

Quite often see my D3 charging at 15.1 volts.
 
I have Varta Blue Dinamic 95Ah 830A in my td5 for about 3 years now and so far it works fine. The only reason why i have chosen this is that NO other alternative were available here in hungary that time (and I did not think that i can order it from the UK).
But next time i will try to get Tayna or similar.

As my battery needs replacing & after looking at this thread I googled the p/no of mine & it comes up with this one, see pic, which in your opinion would be better ? Not sure if the genuine battery fitted to mine is the original, cheers.

My money is on the enduroline if you want to choose between these two otherwise my recommendation remains the same as before
 
Well, I managed to keep this battery ticking over for another 3 years, which is amazing.
As you guys kindly recommended I went to Tanya Batteries for a replacement yesterday and what a company! They have a great web site, easy to navigate and offer a choice of batteries for your particular vehicle. I placed my order for an Enduroline 31-1000 at 1326 yesterday and today at 1130 she arrived superbly packed using Yodel who regularly kept me informed of expected delivery time.
The price at £97 was without doubt the most competitive available and she comes with a 4 year warrantee as well.
All in all I highly recommend Tanya Batteries, you wont get a better battery service. It remains to be seen how long it lasts and just to complete the picture, the previous battery was a Yuasa which lasted 7 years over some 12,615 miles which in itself is a very good performance.
