Largest battery for an eg hatch

[ultravioletvtec]

Hi all,
I'm getting someone to pick me up a replacement battery for my EG.
I just wanted to know what the largest dimensions I could fit are.
I know of many websites that tell you of batteries that fit, but I'm really after the measurements of the bay.

Thanks

Thanks, but am no where near my car.
