I'm using a 25 amp boost charger at the mo and it is a little overkill on the small parts I am doing, however a 50 minute session gets a good depth of ano....your average 4-6 amp charger will do it in 4-6 hrs .....easiest way to do it is trial and error,,,,although if you needed some No's just ask...and I know red does it for you Ronnie
