Because the 6V 'Deep Cycle' batteries have thicker lead plates that simply last longer. And they cope with the repeated charging/discharging cycles better.

Also.... They will hold in reserve twice the power than the 12v. If you want the most out of your solar system, use 6v true deep cycle.

Your current 12v batteries are hooked up in Parallel fashion which still provides 12v of power. If a pair of 6v batteries are connected in Series, you end up with 12v (6+6=12).

The accepted practice of using 6v golf cart batteries (some folks call them "deep cycle") is they are designed for extended drawdown without being damaged. Just imagine the power demands of a golf cart laden with golfers, beer and clubs bouncing around 18 holes of an expansive course. The average 12v battery is for quick starting of a vehicle engine and then immediate recharge as the vehicle is running. There are deep cycle 12v batteries but most folks experience better performance and life from the paired 6v batteries.

First: There may or may not be an advantage depending on the size 12's you have

Group 24, about 75 amp hours, 2 of them 150
Group 27, around 95
Group 29 around 105
Group 31 around 130

Six volt GC-2, about 230 put two in series and you have 12 volt 230 amp hours. (AKA a D-8 If I'm not mistaken, or a D-4 if I am, in either case you don't want to pick one of those suckers up... Or pay for 'em, the sixes are cheaper by the pair)

12 volt batteries are hooked up like this

-{battery}+ 12 volts

Six volt pairs are hooked up like this.

-{Bat}t{ery}+ 12 volts

(The t in the middle is a jumper cable)

Note that the two of them together make a single 12 volt battery.. Think of them that way, Treat them that way, and many of your questions self-answer

Can I replace just one? Can they be different makes, types, sizes whatever?

Would you replace half a 12 volt battery, would you want one that was half one thing and half another?

Same answer.
