Your alternator is NOT a chargerThe alternator’s job is to supply the power needed for all electrical items on the vehicle, plus replenish the battery from the last start up. The alternator is not a battery charger so much as it is a battery maintainer. If the alternator has to recharge an overly discharged battery, the alternator will become over-worked, which will shorten its life.If you use your alternator to charge your dead battery, you will overheat the alternator during its charging process. The greater the amperage flowing through it, the higher the heat an alternator creates.Maximum Alternator Output Only Occurs at high RPMSAfter you start your car with jumper cables, the voltage regulator sees a discharged battery and commands maximum field in the rotor. But at 600 RPM, the alternator can only provide about 1/4th of its rated output. Let it idle for a long period and all you’ll do it overheat the rotor windings and burn up your expensive alternator. A 110-amp alternator can only output 110-amps at RPMS of 2,500 or more. So don’t even think about letting it idle to recharge the battery.A battery charger costs $40. A new Alternator $350Not exactly brain surgery, is it?The correct way to deal with this situation is to jump the battery (using a jumper pack is much safer than jumper cables) and driving it to a place where you can place a REAL battery charger on the battery.

This was much more of an issue a generation ago, when your ‘74 Chevy Nova or ‘69 Ford F-100 had a 35 amp alternator. Any car made in the last 15-20 years will have a 75 amp alternator as a bare minimum, and ratings well north of 100 amps are common in larger vehicles.There’s dozens of amps of headroom to charge the battery at idle speed, especially if you turn off the lights, stereo, HVAC, etc. That said, it’ll charge even more quickly if you drive the car.

This will KILL your alternator. You should get a battery charger or a trickle charger. Alternators go through hell when trying to recharge a fully depleted battery.

The docs say: "When using Rails and Sprockets in development mode, no assets are concatenated."

But ActiveModel doesn't support out of the box argument parsing, e.g. having a datetime attribute be a datetime attribute and a boolean attribute be a boolean attribute.
