I've got a 120d 2008 with start stop technology, I'm after a new battery, can anyone point me in the right direction of a decent battery at a reasonable price.. Does anyone know the manufacturers recommendations?
Oh and what are the best brands to look for?
Have a look at the battery and find the CCA and AH. It'll be written on the top and something like 80AH and probably around 850CCA.
As a minimum you need to replace it with one of the same specs, yours will be AGM type and will need to be coded to the car.
Once you have found a battery with the same specs, make a note of the number. (It'll probably be something like 110 in your case). Mine was 096.
Head over to justcarbatteries.co.uk and have a look on there. I've just bought a Bosch S6 096 from them for £123 delivered, which is AGM and an exact match to my original battery (70AH 760CCA) and comes with a 6 year guarantee.
Fitted and coded myself using the carly app. Find someone local who's got the app, chuck em a tenner for the battery add on and bobs your uncle.
