Battery failure

That was about the best value out of the premium batteries with 5 years warranty from a well known manufacturer, it also had a higher capacity than most of the others.
All things being equal I usually by Bosch, but on this occasion the Varta looked like a better deal.
Like a lot of other members, I've used Tayna before and it's always a good choice, good prices and fairly quick delivery.

I would also recommend Tayna. I recently fitted a new battery in a Mini for someone, unfortunately it needed a big AGM, got a 5yr Bosch from Tayna for a reasonable price, around 2/3 of what other sources wanted. They package the batteries extremely well and delivery has always been very quick.

Just noticed this old post... for future reference, Bosch and Varta are the same battery, made in the same factory - if you are in the market for either, buy which looks the better deal.

Possibly not, a tired battery can be drawing on the engine all the time.

this is a good article about batteries,  defects from battery makers are an extremely small part of battery failure.  It is the way the battery is treated on a vehicle that decides how long it will last and be reliable.  It is well known that in hot countries batteries last for a very short time compared to temperate or cold countries.   Even when a battery has one of those colour changing windows on the top of case it is only showing the specific gravity of acid in that one cell with a floating plastic ball,  so there could be a problem with any one of the other five cells.

Just had to fit a new AGM battery on the Vauxhall, great big bloody thing! Managed to get a Ford OEM Omnicraft branded Varta battery, identical to the original GM factory battery that's on - cost £135, but still £40 cheaper than the Varta.

There's a saving with these OEM batteries, but being OEM parts, warranty is covered by the supplier and not backed by the manufacturer - the warranty is usually shorter. As the original OEM Varta battery lasted 9 years, I'm not too worried.

9 yrs is good going. You had your moneys worth out of it. With luck the replacement will last as long. £135 is some cost, I imagine it's because of S/Stop?

Yes, it's AGM for the start/stop, and it's big - 25KG, and that's about 3 Jazz batteries...

9 yrs, but I've been nursing it since last winter... start-stop has been more miss than hit, and this winter has finally seen it off altogether, it's not holding charge anymore.

I like that the new battery came with a printout with battery serial number and a cranking amps test result on it.
