batteries

Quick question.more than likely non repairable but I broke the neg terminal trying to undo the battery right where it joins into the plastic.is there a possibility of fixing this or better to just buy a new one?..I've clamped it as much as I could so it still works but went for a spin today on some bumpy roads and could feel it surge a fewtimes showing f1 light so it's prob not safe if ya want o push it around corners etc...

Question for the in-the-know guys that one. If it were me id just get a new one to be on the safe side. Of all the things i thinker with terminals wouldn't be one of them x Happy Trails
