Bosch or Varta AGM Battery?

[Alfa1750]

Hi
I want to get a Bosch or Varta AGM
They seem the same
Which makes to generally though the most popular(maybe newer then) and best?

thank you

Buy whichever is cheaper

[Alfa1750]

Good advise

[normalbloke]

Buy it from Tayna batteries, cheaper still.

[AlexGSi2000]

Both good brands, either.

[shtu]

Bosch and Varta are the exact same same batteries.

eg, this,
https://www.tayna.co.uk/car-batteries/bosch/s4001/

is identical to this,
https://www.tayna.co.uk/car-batteries/varta/b18/

There are different ranges, but each range has a direct equivalent in the other brand.

I buy whichever has the longest warranty. From Tayna.

I just replaced my R8 V10 battery. £118 delivered, and it took about an hour to swap ("Frunk" out job). My M3 V8 CS owning neighbour was aghast. He let BMW change his. £680. "its stop start mate, and it needs "coding" thats why"..... lol.

Put mine in and then ran VAGcom to clear all the faults (R-Tronic system got in a strop when trying to start the car with a flat battery). Put a like for like battery in (capacity) so no need to "code" anything (though I of course had to clear fault codes - which I believe would have self cleared eventually)

Bloody hell, thats steep!
Just needs a battery registration or type change if going from AGM to standard - all doable with a £40 cable and some, ahem, software found on the net.

Personally prefer Yuasa.

[stevemcs]

Varta for us, never a fan of Yuassa.

I bought an Exide one for my 2006 BMW Z4 from Tayna for just over £100, because Exide were OE as Z4s of that era were built in Spartanburg, SC.

I bought AGM because it looked like it would work better for a car that isn't a daily, and it didn't need coding.

When I bought an AGM in 2012 for my 2007 BMW123d with stop/start that needed coding it cost over £250 - Sytner quoted over £300!

They've become mush more affordable thankfully.

Varta for me as well. We had problems with Yuassa in the HGV fleet, but it could have been a bad batch.
