Batteries
TT new to me. Two batteries, dated '08, one is 75 amps, one is 675 amps. Its been awhile to have dealt with this. Should the amps be matched or is it like I have one battery? Both are deep cycle, 24dc...

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) :h 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.
