difference between bosch s3 & s4 battery

londonTiger

I have two suitable batteries for my mk4 golf, bosch s3 002 & bosch s4 002 - can;'t link as the carparts4less site uses session cookies for the url.

Anyway, just wonder what is the difference between them? they have their own respective 3,4 year warranty. I was wonderin whether they're the same battery but with different warranties? Or are the 4 year warranty batteries designed better?

Price difference is pretty different £44-£61 (price per year the s3 is actually much cheaper at £14.66 per year and £15.25 per year for the s4).

Will you have the car that long or will it be in bits with your tinkering by then?

Check CCA and Ah the S4 are probably higher.

Aslo check tanya and euro car parts for the same/equivilent.


there are discount codes around for both

Bosch data sheets here (although Australian) explain the difference:-

S4 is a higher Ah capacity and a sometimes a higher CCA figure also.
