Replacement Service Battery AGM 12V/160Ah?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I need to replace my two Service batteries (AGM 2V/160ah). My broker and Boathoom list the Longex AGM 2V/160ah battery as being compatible for Hanse 418s and my boat, a Dehler38. However both of these boats need two batteries with flat terminal heads that protrude far enough for a battery bridge (clamp) to attach them together. I cannot find any AGM 2V/160ah batteries with “flat” not rounded terminals with holes in them to install in these sailboats. Ordering batteries from Germany is also very expensive. West Marine has an AGM 2V/160ah battery but it does not have the flat terminal heads either. What are people using in the US?

	When my AGM 165Ah (x2) bow thruster bank went out, I had similar difficulty. I did go the West Marine route with this one. For clarity, the default picture shows tabs. I didn't get any. Instead, I had just bolts which you'll see if you click on one of the terminal zoom-ins. Those bolts back all the way out. I then bought some copper flat bar. Couldn't find any locally at a variety of electrical supply shops -- thought they would have stock bus bar. Anyway, a company like onlinemetals, speedy metals, etc. I went with 1/4" thick and about an inch wide. Then cut to length, bent a 90 degree, and then drilled holes. Short end to mount to the battery. I think I had to do a few different holes on the longer standing end to accommodate a variety of things hanging off (e.g., voltage monitor, charger and loads etc.). Maybe something like this could work for you. Edited by Lyn - 04 October 2025 at 22:22

	Try looking at Victron AGM’s. I swapped out my factory Q batteries for the Victron 165ah AGM’s and it was an exact fit with the same terminals for the factory joining bars. Didn’t have to modify anything. I bought them from a local supply house that just had them shipped from the Victron warehouse wherever that was - Peterson Marine IIRC, but they were listed at other shops as well online.
