Great question for discussion.

A lead acid battery is an electrochemical energy storage device and "generally" speaking since they use lead n acid to do so, the more lead n acid which also amounts to the more size n weight can store more energy. One advantage of two batteries in paralell is that the available cranking amps and amp/hr ratings is additive, where two in series that isnt true (only the voltages add). HOWEVER, batteries may be more prone to feed n cannibalize off each other in paralell versus them being in series.

Regardless if in series or paralell you wanna use matched batteries to lessen one feeding off the other in my opinion

In the old days they sold batteries rated in Amp/Hrs which gives a good indication of their energy storage capacity while nowadays its more CCA.

For good diesel starting fast cranking to help raise the cylinder temperature and avoid compression leak off is important so those initial CCA'a are needed. Another battery may actually be able to store more energy and could provide more amp/hrs to crank the engine longer but nottttttttt have the high initial CCA to crank it faster. Looks like for a gas engine the longer crank time may be more important but in a diesel its that initial good fast crank over thats needed (even if not as long) i.e. a high CCA rated battery.

I also used to buy those 1050 to 1000 CCA batteries but havent seen them around as much lately?????
