Battery box lid size/biggest battery

Can someone check/tell if a 393mm long battery would fit into the battery box, I have a Numax 019 in there just now which is about 330mm and it fits through the gap, I don't mind if I need to put it in at an angle but I don't want to order it and find it won't fit at all.

I can't check it till the weekend so would be keen to find out what will fit in there so I can order it.

Thanks

If all else fails you could always get the sellotape and cereal boxes out and make a template

HAHA - I've decided to buy a Yuasa 900CCA from Halfords anyway which is an 019 so should be the same size.

I was going to get a Varta 930CCA from Tanya Batteries: 610 200 Varta Silver Dynamic Car Battery 12V 110Ah (Short Code: I1)(Varta DIN: 610 402 092 ) - Car Batteries - Varta Car Batteries but I am not sure if I want it brought via courier, bumped and bashed, one of the no.1 killers for batteries.
