Yes, they have different voltages and charging charateristics... however if you are buying a battery with a charging system, the charger should be designed for the battery. Don't try to charge a battery with with a charger built for different type of battery... at best it won't charge, at worst you may end up with "rapid disassembly" a trade term for "explosion."
Now all that said, lets suppose that you need a 12 volt battery, for your 12 volt lighting system... well chances are your lights don't care about the actual source of the power, so any battery that delivers the right voltage and has the right milliamp-hour rating should work. A bit of a caveat to that... if you don't have the right milliamp-hour rating, again you may find your battery failing unexpectedly.
