### What is difference between 18AH and 22Ah battery?

As the dimensions of the 12 Volt 18Ah battery and the 12 Volt 22Ah battery are the same, they are interchangeable. Amp-Hours basically show how much energy a battery holds. As long as the battery you want to replace has the same voltage and dimensions it is okay to substitute it with a different Ah replacement.
