Is it possible to have too many cold cranking amps? I mean, can it
harm a starter motor?

NRMA guy replaced my dead 700CCA one with an 850, and it kicks over so
quickly now I practically flinch at turning the key. But I was
thinking of getting something similar for the V6 petrol Jackaroo,
since it's battery has probably almost had it too (bought at the same
time as the Hilux one).

The only reason is just the obvious advantage of having
interchangeable car batteries. But not if it's going to cause
potential harm to the starter motor in the Jackaroo.

No harm at all, if anything supplying a starter with more than it needs
will be better because it won't struggle to do its job, more starter rpm
means the engine will start more easily so less work for the starter.
Only issue with a bigger battery is you are carrying extra weight which
I don't think is big issue, as long as the bigger battery fits and can
be secured then do it.
When the battery in my 03 petrol Hilux failed it happens across the road
from a 4WD workshop so I didn't have much choice about where to buy the
new battery, they suggested fitting a diesel size battery which was much
bigger than the original and it worked very well till I traded it in in
the new Lux.

Not unless it's got a fault to begin with (highly unlikely)!

Unless you plan on replacing the cars in the near future do yourself a
favour and spend a bit extra for calcium techology... Delkor or Alco.
The same size battery will have an even higher cranking current.

I've got well over twenty batteries in service (haven't done an exact
count lately) and the replacement rate has more than halved since
they've all been changed over to calciums (including the lawnmower).
The main reason for the exceptionally longer life is the vastly lower
failure rate... I've only ever had one calcium battery fail at less
than three years old. For premium brand lead acid the under 2 year
failure rate was over 30% (cheapies are worse).

Other advantages are the complete absence of external corrosion and
their low discharge rate (unlike lead acid, they take forever to go
flat when not in regular use).

Cool, sounds good to me :)

I don't think we'll have the Jackaroo anymore after this year, but
since it is the primary child transporter, I do like to keep it in the
best running order possible.

Well here's the thing. Last time (3 years ago) I tried to do exactly
that. Rang up about them and was told that they do have them, but when
I arrived the response was told "well, there really isn't such a thing
as 'calcium batteries'." So without any technical knowledge of them
myself, I wasn't able to argue about it.

But now you've mentioned Delkor and Alco, I can at least look them up
and hopefully have more luck this time.

Sounds great to me. This last battery only lasted 3 years and 11 days.
