I'm thinking of installing the Bosch H6/L3/48 in my r55 since it has 70Ah like my original battery, but is 1.25" longer (10.8" total length). Pepboys says it'll go in there, but it looks tight. Have any of you installed a battery that size? Did you have to do anything special?

 

You can always return it if it doesn't fit. Take measurements if you dont want to go through the hassle of returning.
