The 9200 charges lead acid batteries (AGM, flooded wet cell, gel )
When I had an AF , I had the same converter and I added the plug in charge wizard . It acts like a brain to monitor the whole charging process. Some converter models have it built in, others like the 9200 have a plug in additional wizard that you have to buy.
charge wizard Read #7....if you have a 9200.
9200lead acid battery sub divisions are wet cell (flooded) gel and agm .BTW...I paid $190 for my AGM Deka and the chart in my link (previous post) shows CCA 800. You mentioned you needed a high CCA for the genny starting.
