I managed to get (3) cans (12 oz) to charge. the 4th one was taking forever, and i think there is still a little left. the site glass is still cloudy and lots of bubbles so I think I need more.

How many cans do I need for a complete re-charge for a 560 SEL?

I found it quite long for one can to charge. I had to use hot water to get the process going. And even with hot water, I was not able to get the 4th can totally consumed with more than 2 hours trying.

Capacity should be around 2.9lbs.

so should I go by the capacity spec or the site glass. it is impossible to measure how much actually got charged.
