Both are 75 amps.. On one you are reading Amp hours (75) and on the other cranking or cold cranking amps. That is about right for a Group 24
Second: Batteries in parallel need not be the same
Batteries in SERIES do need be the same
You have about 60-70 usable amp hours there
Easist upgrade... IF you wish and have the HEIGHT (They are taller) woudl be a pair of GC-2 (5 volt) in series.. These batteries have around 220 amp hours and you can use 110 of them..That's over 50% more capacity with the same footprint.
