Battery....damn it!!

Take £100 off of that as they do their stupid 'massive weekend crazy discount' pricing.

Eurocarparts are the DFS of the car parts world.

Don't use ECP, without discounts they are overpriced. Check Tanya or batterymegastore. If all you purchased was the battery and you did it by card then a bank statement is enough proof of purchase.

Intesting, thank you - it was all I purchased, will give it a try on Thursday.

You may have a bit of a fight, let me know if they give you any grief.

Dear lord

You shouldn't need an AGM unit unless you have stop-start, a good non-AGM battery should be well under £100, keep away from cheap Chinese made stuff and any brand you have heard of are often made in the same factory e.g. Varta are Bosche etc

Guessing I must have put it on credit card & my online banking doesn't go back that far. Looks like I will have to just pay for it then.

Got a friend dropping off a multi meter today, and took the CTEK off yesterday so will see what the charge is like tonight if I get home from work at a decent time. Tempted to just order a battery so that if it is simply the battery, I can get out in the M over Easter.

Surely must be battery rather than alternator, as would a car be able to travel on just its battery for 20 miles without dying?!

I was only going AGM as it was what it came with from the factory.

Found a Bosch AGM one for £130 ish, so not too bad.

also worth looking at the voltage regulator on the alternator. hope you come right mate!

 

[derin100]

Which model of CTEK do you recommend for our cars/batteries in terms of value for money? I could actually do with buying four so cost is a consideration!

A link to a good place to buy would be great.

Many thanks in advance.

I don't even know what an alternator looks like, or where it is....will be googling tonight!

CTEK 5.0 was the one I purchased as it does AGM batteries.

I got mine at a good price from amazon at the time - no idea what the prices are like now

Yeah google FTW!!

a friend of mine also had similar issues with his Z4MR recently, he replaced the battery and still had problems.. turned out to be an old tired voltage regulator on his alternator... he got one off Ebay and fitted it, car was well after that...

Fingers crossed it is just a battery - its only done 25k so id rather have hoped nothing has worn out or got tired yet

Are you sure it was AGM from factory, I don't believe my original battery was AGM.

I only assumed it was based on what I read here - and certainly the one that I removed was....and IIRC the year code seemed to put it aligned to the age of the car (realised at the weekend the car was first registered on my 30th birthday - sad fact, but a special one !)

11.1v and barely able to start after just 24hrs off the CTEK

Once it started, there was a healthy 14.6v across the terminals, which based on my research would suggest it is reasonably safe to say it's not the alternator

 

[mj2k]

So I have the choice between these two

https://www.tayna.co.uk/S5-A08-Bosch-AGM-Car-Battery-Type-096-S5A08-P9809.html

The non AGM has a higher CCA and Ah, so what exactly is the benefit of the AGM???

 

[srhutch]

Save your money and get the non AGM one. The extra £50 will do nothing for you or the car. The alternator charges all the time, we have non electric power steering, no stop start technology so there really is no need for AGM.

 

[pvr]

AGM was only a requirement for start/stop, and I have never seen a Z with an AGM battery. Mine was a 2007, so no idea if they fitted later cars with it? Seems strange to me though as electrically, the M is old technology.

Excellent, thanks gents
