Hi all- looking to change the battery on my E89 2012 2.0 m-sport manual and getting confused with what size it needs - its got stop start so I know it needs the AGM type. Haven't got any means of registering it myself so will have to get it fitted by someone who knows what their doing - checked ECP and it says i need 096 AGM -( the spec seems to match with the original BMW battery thats fitted that is made by exide) - cost of the replacement exide battery is circa £170 delivered with discount but then need fitting. Checked AA and RAC websites and they say it needs a larger battery 115AGM and are charging in the region of £250 fitted. Checked tanya batteries and can get the same exide battery for £120 delivered with fitting at a local garage for £15 through their website ! Anyone recently fitted a new battery to their 2.0 e89 and what size did you fit - anyone used tanya batteries as it seems very cheap compared to other websites/garages. Many thanks in advance G
