As everyone has said all along, if you're building a charger do it properly with a transformer - if you're "throwing together" something in an emergency, then you could always use the crude bulb method, but you certainly shouldn't be thinking of building one for permanent use!.
1 It is a poor way to charge a battery.
2 It is bad from a personal safety viewpoint.
3 Depending on the current, you will overcharge any battery if you leave it long enough.
4 If the devil is biting at your arse and you have to charge the battery, this method will get you going.
