[QUOTE="maylar, post: 8597, member: 541144"] Car batteries are rated in amp-hours over a 10 hour disharge. example: A 75 amp-hour battery will provide 7.5 amps for 10 hours. A 100 amp-hr batt will give 10.0 amps for 10 hrs. etc. The time you get with higher discharge rates decreases exponentially with how much current you draw. A 100 amp-hr battery will NOT give you 100 amps for 1 hour. It's more like 5 minutes. [/QUOTE]
