To go back to the original point of this thread, since the Optimas have been ruled out (rightly or wrongly), need to find some batteries. This one: Numax CXV24MF Heavy Duty Maintenance Free Leisure Marine Battery 86 Ah 900 CCA | eBay that DHD recommended on another thread looks good and fits in the red box which is what I want. Perfect for the starter battery, but what about the house...is that not sacrificing Ah for CCAs? Can anyone recommend a 110ah that fits in a red battery box?

I doubt you'd get a 110Ah battery to fit in a red box. You could run 2 of the CXV24MF batteries, in which case you'd have a decent starter back-up, should your main one fail. Nice bit of insurance. Do you anticipate much deep cycling of the aux battery, eg running an anchor light overnight, or lazing around at anchor with a cool box running off 12v? (don't ask how I know about the latter.......)

Not really..but it will be used for powering the bilge pump on the mooring

Yes. Generally the plates are larger and thicker to cope with high CCA which reduces their surface area and therefore Ah.

IIRC I have a basic leisure battery (squadron SFL) in my console which sits happily in a red box. Pretty sure it's 100 or 110Ah. Never been a problem yet with it sitting on the mooring operating the bilge pump and also starting the engine.

Finito!

It has been very well done except the batterys are mounted to port thanks to a loss in translation

Will be interesting to see if it will be worth the hassle of moving them during a sea trial tomorrow.

"Batterys"? People in glass houses. Here's me thinking that you're effluent in several langue
