So I have a 24v trolling motor. The batteries I have are junk so I'm looking to replace them. They are old and I can't read the info on them. I have a 70lb Minn kota on a 18ft boat. 


Can anyone tell me if these will work? I'm tight on cash at the moment but obviously want to get something that will work.

If anyone else has suggestions that are under 100 each to buy please let me know. I saw with shipping these are like 75 each. Would just a deep cycle marine set work? I guess I'm not sure on what AH they should be and any other size recommendations.

Thanks

Mike
