The exact amp-hour (Ah) rating for the 12-volt battery can vary depending on the manufacturer and model of the battery, but typically, these batteries are in the range of 40 to 70 Ah.

I would go with the CCA which on the old battery is 650. Here is how to change the battery out which will need to be programmed unless you connect a 12 volts power source which we show you how to do in the video.

So, what i should do is get a battery which fits and has 650 CCA, no matter what AH it has? I've seen the same size and CCA battery have different AH, one can have 40 the other 70 , how should i choose one?

The 70 AH will be a better battery and should last longer when cranking for a longer period of time. That will be the difference.
