I have build this charger back in 1993, it its working !!!!!!
Using a fully charged battery adjust the "P" until the Green LED just about start to go ON. ~14v~

This circuit is from Hobby elektronika 1991/11

Good luck

You may get a suitable circuit from National Semiconductor Data Sheet for LM350/150. I've built this and now it is up & running.
