Largest battery for R51 Pathfinder

[floatingkiwi]

Hi Folks

My Dad has a 2010 Spanish Ti 450 pathfinder, and the battery is stuffed. The batt tray seems quite small for the place it's in, and it's too small to get a 305mm battery in. Whats the largest battery I can get in the thing or is there another tray that will fit?

R20 Spanish assembled mistral tray. I had 305x200 mm 8 cell 770cca batteries. One each side.

A 305mm battery is a 27 box size, so if that wont fit you will be stuck using a 24 box size. The grunt winner in that size is a red top optima at 1000cca. Bit pricey but very good batteries.

I was thinking of trying one of the exide orbitals (supercharge brand). He will have a winch shortly too.

Here we are again with My dad's 2010 pathfinder. The 4 yr old MF66 has died many times and tests badly now. What is the biggest sucker I can get in that size? Diff battery trays are not an option right now. Is there a dual batt kit? Seems no room for a second battery anywhere.
