Bare in mind N120/N150/N200 size batteries are physically massive, have thicker plates and a lot more solution inside them, if you look at their low CCA rating in comparison to their size and weight I think there's something in that in comparison to the car type.
If you look at ye olde Century 86, it's a bit bigger than an N70Z size what you'd have in a diesel Hilux but it doesn't have much of a CCA rating, it's much heavier, it's maintenance type and it lasts a very long time.
Everyone's failures here have been latest generation car maintenance free century stuff.
Might be something in this.
For reference to what I'm talking about look at CCA, physical dimensions and weight

There's not much CCA there but there's lots of weight.
