I have just bought a March 2007 Corsa 1.2 petrol "Life". The battery on this car is an RAC 1OO which I have never heard of. It says on the side of the casing that is a Serial number YB1047580. My last car was a 1999 1.2 Corsa and that had the original Vauxhall battery . Why would a 4 year old car need a new battery? Are these RAC 100 batteries any good? It says it is a 47 amp per hour which is slightly higher than the Vauxhall spec( 45). I think it is a maintenance free battery because it has the " green eye" but there are also three plugs which look like they can be unscrewed with a Phillips screwdriver. The previous battery also had the green eye but had no plugs at all on it. Any information on this battery will be much appreciated.
