What is the Best way to connect to Battery FL1 terminal?
Should I just use a nut/bolt/washer or is there a better way?

I installed mine with stainless steel bolts, washers, nuts and lock washers.

So what IS the FL1 terminal....please ??


It's a specific design of battery post (a "flag terminal 1"). Landyacht's picture shows a battery with FL1 terminals. If you prefer technical drawings, see page 5 of this PDF.

Lifeline uses a berrylium copper post and bolt. Mine has turned orangish I suspect from oxidatio.. I will brush it bright and coat it.

And I STILL don't. ?????

You have AGM batteries. The likelyhood of corrosion is MUCH less than with conventional types so just being sure the contact surfaces are perfectly clean should be enough. An appropriately sized star washer can give a little extra piece of mind.

+1 on the thick walled ring terminal held tight with bolt and lockwasher.

Make sure the hole diameter on the lug is no wider than on the FL1 terminal.

Perhaps one could go a step further and acquire silicon bronze bolt nut and washer.

I'd use a ring terminal held on with a bolt and a flat washer/split lock washer/nut. The ring terminal and the battery terminal should be in contact, with no washer intervening, assuming a permanent attachment. For a battery charger or similar temporary connections, I see no reason why the usual alligator clamps would not be perfectly adequate.
