Cayman 2.7 Battery.

[Chrisp5782]

Well it's finally happened, the battery on my 2.7 Cayman has finally given up the ghost.

I'm not going to moan about it as it's lasted 7 years without ever giving any dramas but it's as flat as they come now and won't take a charge.

Due to the age of the car I'm not going to go down the Porsche battery route and was thinking of getting a Bosch replacement.

Has anyone got any other recommedations for after market batteries before I buy?

[mrdemon]

nope I would go Bosch

As long you get approximately the same Ah and CCA rating, I don't think there's much difference.

Bosche & Varta both seem to give 5 year warranties on batteries for Boxsters / Caymans, Exide only 3.

Mine is a Moura (more expensive than Bosch and 4 yrs!) but was on the car when I bought it.

Bosch here in a 987 2.7 Boxster as a replacement for the original batter - just can't remember whether it was an S3, S4 or S5.

I bought a Varta from this lot for my Golf Gti It was a painless transaction with free delivery next day and I saved 40% on any other quote. Fitting took me 10 minutes.

I buy quite a few batteries from Manbat, they are "own brand" but last perfectly well. If you're anywhere near me drop me a PM - I buy at trade price..

Edit - you're in Dorset, so nowhere near me. Numax is the brand name if that helps.

Eurocarparts often do good deals on Bosch batteries.

[Chrisp5782]

Thanks very much everyone. I think I'll go with the Bosch, I can get a good deal and pick it up just down the road.

Thanks again all.

Bosch Silver. Can't remember which, got it from EuroCarParts. You did really well to get 7 years out of the Porsche POS.

Bosch S5 is a great battery, 5 year warranty and very powerful, you will notice a big difference in how it starts!!

[Chrisp5782]

It's the Bosch S5008 I'm going for - slightly higher CCA and 77Ah compared to the 70Ah of the original Moll Kamina Porsche battery fitted but it's one of the few available that match the case size of the original battery exactly.

A five year warranty can't be sniffed at either!

Careful! According to my dealer, bigger batteries make the alternator explode and kill baby kittens:

That's mint from your OPC! What utter crap, 7Ah larger won't do any damage to the alternator at all, it doesn't have to work any harder. The average car battery is topped up (depending on state of original charge) within about 9 miles of driving.

I went for Yuasa (75Ah 650CCA) in the end £70 and 3 year guarantee from the local auto parts store. If it lasts a couple of years I'll be happy I will invest in a Ctek conditioner now though as the car doesn't get used much any more.

Is there a consensus on which Bosch will do, S3/S4/S5?

Think mine could do with replacing, went flat when the Boxster was in the garage for a week and a half.
