After I installed the Tri-Metric battery monitor I realized how little those indicator lights really mean.
Your charging system and actual state of discharge will be the biggest determining factors on your re-charge time. I'm not familiar if they are putting advanced converter/charging systems as standard equipment or not. Some will give you the option to use a plug in module to gain the advanced capabilities. Regardless, if you are at 11 volts now you are more than likely below 50%.
