I was wondering what the difference between the ad-244 alternator and the 140 amp one that NAPA has?

i'm new to this ad244 alt and that napa one won't cut it. i got a used ad 244 last week and it's better, mine is the 130 a . the ad alts puts out more amps at
idle rpms . i had my air at max ,headlights on and it was in drive volt meter stayed at 14 v now with the 105a i had the meter would drop way to the left
in park with it in drive it was worst. thats the diff. i'm going to get the DR44G THATS RATED at 145 a this is the same size as the ad244 the dr44 will

be for my system. i have dual alts
