Thanks to all!
I have some trouble with Varta brand, because I can't find battery with screwed poles.

I find that battery, made by "Fiamm": FG2A007, 100 Ah AGM: do you know something about it?

Datasheet:

I don't know how to interpretare the numbers in diagrams... :)


If You tell me that's ok I'll proceed to buy it!
