Well, the voltage is the same. But the 80 mAh is only 1/7th of the capacity of the 550 mAh. Or the 550mAh is 7 times greater than the 80mAh.
Meaning that size-wise the bigger is unlikely to fit where the smaller went. And if you replace the bigger with the smaller, runtime of the whatever it's supposed to power will be a lot shorter.
You need a DC power supply in order to connect a 24v DC motor to household power.
Use a fuse
multiplies source voltage, two 12v dc batteries in series become a 24v circuit; also multiplies resistence
smps out voltage is 12volt.. A switch mode power supply can have an output voltage of any value. However, common values are 5, 12 and 24V.
It depends. The 2A current, did you measure that while the soldering iron was on? Or is it rated at 2A current consumption on the device itself (on the powercable or the stem of the soldering iron). Generaly speaking you can calculted the real power consumption by using P=V*I (thus 2A*24V = 48W). But do remeber that this power consumption is in the steady state, that is, after its switch on and all transient effects have died down. To be safe allow for 3A-4A switching currents that occurs at power on.
You don't need anything. A 24v system is the cranking volts. The accessories are done for 12 volts.
No its not. Its for 24v security cameras.
You don't. 2 12v panels together don't make 24v - doesn't work that way. If you need 24v you need to get 24v panels.
To determine the amperage for a 24V 200AH battery, you use the formula: Amperage = Capacity (AH) / Voltage (V) So for a 24V 200AH battery: Amperage = 200AH / 24V = 8.33 amps
Of course it is bad, whether it`s humming or not.
A 24V transformer plug-in typically requires an input voltage of 120V AC and outputs 24V AC. It should be compatible with devices that require a 24V power supply. Make sure to check the wattage and current ratings to ensure compatibility with your device.
Apply 24v and listen for click Ck coil for open with ohmmeter Clean contacts if possible
The recommended voltage requirement for a thermostat compatible with a 24V transformer is 24 volts.

You need a 24v to 12v converter. Truck stops either keep them in stock or can get you one.
