Hy, I have AGM batteries on the boat and I know what that was like at that time for a HickHack, for example charger ect. Now my in the car is not so great anymore, and I still have a suitable good AGM over. Can I just install and connect them? If you ask yourself what exactly the difference is, to my knowledge, you can charge the AGM faster and higher, and these would have sealed chambers like a kind of gel, instead of liquid. The newer cars already have many AGM inside, which I also have Wondering if I’m gonna break something on the on-board electronics or something like that!? THANK YOU in advance lg
