What's the largest battery you can fit under the rear seat?

Largest as in, dimensions and Cold Cranking Amperes?
Or has anybody fitted a pair of batteries either side of the tunnel in parallel?

I’ll have a look to see what battery type I fitted.

Funny you should ask. I was using this recently to find a battery for a car which was proving difficult.

So std fit 063 45ah and 380CCA If you are using original clamps then really the width is pretty limited to the original 175mm. You may get away with a couple more mm. Without getting under there and measuring the floor space to be certain i dont know but length wise 225mm may fit. And height can come up a bit with proper terminal covers fitted.

A 111 might just go in and would be a big capacity increase. I hope that helps

I have no battery holddowns on my floorpans, so I can go a little larger than stock. I'll need to measure the actual flat surface to get a base size.
